Besides to develop the precursor of cocoa flavour, it also induce the colour changes in the beans.The fermentation process is reported to be influenced by duration of pod storage and fermentation. Therefore, this study was conducted to evaluate colour of Malaysian cocoa beans and how the pods storage and fermentation duration using shallow box technique will effect on it characteristics. There are two factors being studied ie duration of cocoa pod storage (0, 2, 4, and 6 days) and duration of cocoa fermentation (0, 1, 2, 3, 4 and 5 days). The experiment is arranged in 4 x 6 factorial design with 24 treatments and arrangement is in a Completely Randomised Design (CRD). The produced beans is inspected for colour changes under artificial light during cut test and divided into four groups of colour namely fully brown, purple brown, fully purple and slaty. Cut tests indicated that cocoa beans which are directly dried without undergone fermentation has the highest slaty percentage. However, application of pods storage before fermentation process is found to decrease the slaty percentage. In contrast, the percentages of fully brown beans start to dominate after two days of fermentation, especially from four and six days of pods storage batch. Whereas, almost all batch have percentage of fully purple less than 20%. Interestingly, the percentage of purple brown beans are scattered in the entire beans batch regardless any specific trend. Meanwhile, statistical analysis using General Linear Model showed that the pods storage has a significant effect on the colour characteristic of the Malaysian dried beans compared to fermentation duration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocoa%20beans" title="cocoa beans">cocoa beans</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20box" title=" shallow box"> shallow box</a> </p> <a href="https://publications.waset.org/abstracts/34006/colour-characteristics-of-dried-cocoa-using-shallow-box-fermentation-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">491</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">360</span> A Chemical-Free Colouration Technique for Regenerated Fibres Using Waste Alpaca Fibres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Abdullah%20Al%20Faruque">M.

However, the toxic effect of some synthetic colorants due to long-term exposure can cause several health threats including cancer, asthma and skin diseases. Moreover, in colouration process, these colourants not only consume a massive amount of water but also generates huge proportion of wastewater to the environment. Despite having the environmentally friendly characteristics, current natural colourants have downsides in their yield and need chemical extraction processes which are water consuming as well. In view of this, the present work focuses to develop a chemical-free biocompatible and natural pigment based colouration technique to colour regenerated fibres. Waste alpaca fibre was used as a colourant and the colour properties, as well as the mechanical properties, of the regenerated fibres were investigated. The colourant from waste alpaca was fabricated through mechanical milling process and it was directly applied to the polyacrylonitrile (PAN) dope solution in different ratios of alpaca: PAN (10:90, 20:80, 30:70). The results obtained from the chemical structure characterization suggested that all the coloured regenerated fibres exhibited chemical functional groups of both PAN and alpaca. Furthermore, the color strength was increased gradually with the increment of alpaca content and showed excellent washing fastness properties. These results reveal a potential new pathway for chemical-free dyeing technique for fibres with improved properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alpaca" title="alpaca">alpaca</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical-free%20coloration" title=" chemical-free coloration"> chemical-free coloration</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20colorant" title=" natural colorant"> natural colorant</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylonitrile" title=" polyacrylonitrile"> polyacrylonitrile</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20consumption" title=" water consumption"> water consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20spinning" title=" wet spinning"> wet spinning</a> </p> <a href="https://publications.waset.org/abstracts/96356/a-chemical-free-colouration-technique-for-regenerated-fibres-using-waste-alpaca-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96356.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">359</span> Untargeted Small Metabolite Identification from Thermally Treated Tualang Honey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lee%20Suan%20Chua">Lee Suan Chua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the effects of thermal treatment on Tualang honey sample in terms of honey colour and heat-induced small metabolites. The heating process was carried out in a temperature controlled water batch at 90 °C for 4 hours. The honey samples were put in cylinder tubes with the dimension of 1 cm diameter and 10 cm length for homogenous heat transfer. The results found that the thermal treatment produced not only hydroxylmethylfurfural, but also other harmful substances such as phthalic anhydride and radiolytic byproducts. The degradation of honey protein was reported due to the detection of free amino acids such as cysteine and phenylalanine in heat-treated honey samples. Sugar dehydration also occurred because fragmented di-galactose was identified based on the presence of characteristic ions in the mass fragmentation pattern. The honey colour was found getting darker as the heating duration was increased up to 4 hours. Approximately, 60 mm PFund of increment was noticed for the honey colour with the colour change rate of 14.8 mm PFund per hour. Based on the principal component analysis, the chemical profile of Tualang honey was significantly altered after 2 hours of heating at 90 °C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=honey%20colour" title="honey colour">honey colour</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxylmethylfurfural" title=" hydroxylmethylfurfural"> hydroxylmethylfurfural</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20treatment" title=" thermal treatment"> thermal treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=tualang%20honey" title=" tualang honey"> tualang honey</a> </p> <a href="https://publications.waset.org/abstracts/39448/untargeted-small-metabolite-identification-from-thermally-treated-tualang-honey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39448.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">358</span> The Effect of Transparent Oil Wood Stain on the Colour Stability of Spruce Wood during Weathering </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eliska%20Oberhofnerova">Eliska Oberhofnerova</a>, <a href="https://publications.waset.org/abstracts/search?q=Milos%20Panek"> Milos Panek</a>, <a href="https://publications.waset.org/abstracts/search?q=Stepan%20Hysek"> Stepan Hysek</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Lexa"> Martin Lexa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays the use of wood, both indoors and outdoors, is constantly increasing. However wood is a natural organic material and in the exterior is subjected to a degradation process caused by abiotic factors (solar radiation, rain, moisture, wind, dust etc.). This process affects only surface layers of wood but neglecting some of the basic rules of wood protection leads to increased possibility of biological agents attack and thereby influences a function of the wood element. The process of wood degradation can be decreased by proper surface treatment, especially in the case of less naturally durable wood species, as spruce. Modern coating systems are subjected to many requirements such as colour stability, hydrophobicity, low volatile organic compound (VOC) content, long service life or easy maintenance. The aim of this study is to evaluate the colour stability of spruce wood (Picea abies), as the basic parameter indicating the coating durability, treated with two layers of transparent natural oil wood stain and exposed to outdoor conditions. The test specimens were exposed for 2 years to natural weathering and 2000 hours to artificial weathering in UV-chamber. The colour parameters were measured before and during exposure to weathering by the spectrophotometer according to CIELab colour space. The comparison between untreated and treated wood and both testing procedures was carried out. The results showed a significant effect of coating on the colour stability of wood, as expected. Nevertheless, increasing colour changes of wood observed during the exposure to weathering differed according to applied testing procedure - natural and artificial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colour%20stability" title="colour stability">colour stability</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20and%20artificial%20weathering" title=" natural and artificial weathering"> natural and artificial weathering</a>, <a href="https://publications.waset.org/abstracts/search?q=spruce%20wood" title=" spruce wood"> spruce wood</a>, <a href="https://publications.waset.org/abstracts/search?q=transparent%20coating" title=" transparent coating"> transparent coating</a> </p> <a href="https://publications.waset.org/abstracts/73590/the-effect-of-transparent-oil-wood-stain-on-the-colour-stability-of-spruce-wood-during-weathering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73590.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">357</span> Radio Frequency Identification Chips in Colour Preference Tracking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Ballard">A.

Recently the emergence of radio frequency identification (RFID) technology has enabled this better than ever before. However, a significant problem exists in that RFID technology depends on the quality of the information stored for each tagged product. Because of the profusion of names for colours, it is very difficult to ascertain that stored values are recognised by all users who view the product visually. This paper reports the findings of a study in which 50 consumers and 50 logistics workers were shown colour swatches and asked to choose the name of the colour from a multiple choice list. They were then asked to match consumer products, including toasters, jumpers, and toothbrushes, with the identifying inventory information available for each one. The findings show that the ability to match colours was significantly stronger with the color swatches than with the consumer products and that while logistics professionals made more frequent correct identification than the consumers, their results were still unsatisfactorily low. Based on these findings, a proposed universal model of colour identification numbers has been developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20preferences" title="consumer preferences">consumer preferences</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20logistics" title=" supply chain logistics"> supply chain logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency%20identification" title=" radio frequency identification"> radio frequency identification</a>, <a href="https://publications.waset.org/abstracts/search?q=RFID" title=" RFID"> RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=colour%20preference" title=" colour preference"> colour preference</a> </p> <a href="https://publications.waset.org/abstracts/126493/radio-frequency-identification-chips-in-colour-preference-tracking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126493.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">356</span> The Relationship of Anthocyanins with Color of Organically and Conventionally Cultivated Potatoes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Murniece">I.

Srivastav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rohu (Labeo rohita) is an Indian major carp and highly relished freshwater food for its unique flavor, texture, and culinary properties. It is highly perishable and, spoilage occurs as a result of series of complicated biochemical changes brought about by enzymes which are the function of time and storage temperature also. The influence of storage temperature (5, 0, and -5 °C) on colour and texture of fish were studied during 14 days storage period in order to analyze kinetics of colour and textural changes. The rate of total colour change was most noticeable at the highest storage temperature (5°C), and these changes were well described by the first order reaction. Texture is an important variable of quality of the fish and is increasing concern to aquaculture industries. Textural parameters such as hardness, toughness and stiffness were evaluated on a texture analyzer for the different day of stored fish. The significant reduction (P ≤ 0.05) in hardness was observed after 2nd, 4th and 8th day for the fish stored at 5, 0, and -5 °C respectively. The textural changes of fish during storage followed a first order kinetic model and fitted well with this model (R2 > 0.95). However, the textural data with respect to time was also fitted to modified Maxwell model and found to be good fit with R2 value ranges from 0.96 to 0.98. Temperature dependence of colour and texture change was adequately modelled with the Arrhenius type equation. This fitted model may be used for the determination of shelf life of Rohu Rohu (Labeo rohita) Fish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=first%20order%20kinetics" title="first order kinetics">first order kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=biochemical%20changes" title=" biochemical changes"> biochemical changes</a>, <a href="https://publications.waset.org/abstracts/search?q=Maxwell%20model" title=" Maxwell model"> Maxwell model</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=texture" title=" texture"> texture</a>, <a href="https://publications.waset.org/abstracts/search?q=Arrhenius%20type%20equation" title=" Arrhenius type equation"> Arrhenius type equation</a> </p> <a href="https://publications.waset.org/abstracts/57115/kinetic-modeling-of-colour-and-textural-properties-of-stored-rohu-labeo-rohita-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57115.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">354</span> Enhancing the Dyeability and Performance of Recycled Polyethylene Terephthalate with Hyperbranched Polyester</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haroon%20Abdelrahman%20Mohamed%20Saeed">Haroon Abdelrahman Mohamed Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongjun%20Yang"> Hongjun Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to examine the impact of hyperbranched polyester (AA-Ph) on the dyeability and color fastness of recycled poly (ethylene terephthalate) (RPET) fabric. AA-Ph was synthesized through single-step melt polycondensation of adipic acid (AA) and phloroglucinol (Ph) and then incorporated into RPET before spinning. The addition of AA-Ph significantly improves the dye uptake of recycled PET when dyed with disperse dye blue 56 due to the introduction of polar groups and aromatic rings. The blends RPET-3 and RPET-5 show strong abrasion resistance, dyeability, and washing fastness. Furthermore, these blends exhibit high moisture absorbance owing to the polar groups and aromatic structures, as demonstrated by exhaustion tests, which enhance perspiration absorption for added comfort in apparel. Overall, RPET-3 and RPET-5 blends are well-suited for various textile applications, especially in garment manufacturing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycled%20poly%20%28ethylene%20terephthalate%29" title="recycled poly (ethylene terephthalate)">recycled poly (ethylene terephthalate)</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbranched%20polyester" title=" hyperbranched polyester"> hyperbranched polyester</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeability" title=" dyeability"> dyeability</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20blue" title=" dye blue"> dye blue</a> </p> <a href="https://publications.waset.org/abstracts/194927/enhancing-the-dyeability-and-performance-of-recycled-polyethylene-terephthalate-with-hyperbranched-polyester" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194927.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">353</span> Reactive Dyed Superhydrophobic Cotton Fabric Production by Sol-Gel Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuddis%20B%C3%BCy%C3%BCkak%C4%B1ll%C4%B1">Kuddis Büyükakıllı</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The pretreated and bleached mercerized cotton fabric was dyed with reactive Everzol Brilliant Yellow 4GR (C.I.

Blanching and steaming processes on cauliflower retained most of the ascorbic acid content (AAC) compared to those of boiling. As for the total phenolic content (TPC), blanching process retained a higher TPC in cauliflower compared to those of boiling and steaming processes. There were no significant differences between the TPC of boiled and steamed cauliflowers. As for the colour measurement, there were no significant differences in the colour of the cauliflower at different lead time (after processing to the point of consumption) of 30 minutes interval up to 3 hours but there were slight variations in L*, a*, and b* values among the thermal processed cauliflowers (blanched, boiled and steamed). The cauliflowers in this study were found to give a desirable white colour (L* value in the range of 77-83) in all the three thermal processes (blanching, boiling and steaming). There was no significant difference on the effect of lead time (30-minutes interval up to 3 hours) in raw and all the three thermal processed (blanched, boiled and steamed) cauliflowers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid" title="ascorbic acid">ascorbic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=cauliflower" title=" cauliflower"> cauliflower</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolics" title=" phenolics"> phenolics</a> </p> <a href="https://publications.waset.org/abstracts/17263/the-effects-of-blanching-boiling-and-steaming-on-ascorbic-acid-content-total-phenolic-content-and-colour-in-cauliflowers-brassica-oleracea-var-botrytis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17263.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">351</span> Effects of Plumage Colour on Measurable Attributes of Indigenous Chickens in North Central Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joseph%20J.%20Okoh">Joseph J.

The overall average body weight of the chickens was 1.95 ± 0.03kg. The body weights of black, white, black/white, brown, black/brown, grey and mottled chicken however were 1.87 ± 0.04, 1.94 ± 0.04, 1.95 ± 0.03, 1.93 ± 0.03, 2.01 ± 0.04, 1.96 ± 0.04 and 1.94±0.14kg respectively. Only body length did not vary by plumage colour. The others; body weight and width, shank, comb and breast length, breast height (p < 0.001), beak and wing lengths (p < 0.001) varied significantly. Generally, no colour was outrightly superior to others in all body measurements. However, body weight and breast height were both highest in black/brown chickens which also had the second highest breast length. Body width, shank, beak, comb and wing lengths were highest in grey chickens but lowest in those with white colour and combinations. Egg quality was on the other hand mostly lowest in grey chickens. In selection for genetic improvement in body measurements, black/brown and grey chickens should be favoured. However, in view of the known negative relationship between body weight and egg attributes, selection in favour of grey plumage may result in chickens of poor egg attributes. Therefore, grey chickens should be selected against egg quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20weight" title="body weight">body weight</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous%20chicken" title=" indigenous chicken"> indigenous chicken</a>, <a href="https://publications.waset.org/abstracts/search?q=measurements" title=" measurements"> measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=plumage%20colour" title=" plumage colour"> plumage colour</a> </p> <a href="https://publications.waset.org/abstracts/101953/effects-of-plumage-colour-on-measurable-attributes-of-indigenous-chickens-in-north-central-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">350</span> Polypropylene Fibres Dyeable with Acid Dyes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20M.%20Wang">H.

In order to reduce the consumption of petrochemical raw materials and reduce carbon emissions, low-carbon fiber materials have become key materials in the future global textile supply chain. This project uses polyolefin raw materials to modify through synthesis and amination to develop low-temperature dyeable polypropylene fibers, endow them with low-temperature dyeability and high color fastness that can be combined with acid dyes, and improve the problem of low coloring strength. The color fastness to washing can reach the requirement of commerce with 3.5 level or more. Therefore, we realize the entry of polypropylene fiber into the clothing textile supply chain, replace existing fiber raw materials, solve the problem of domestic chemical fiber, textile, and clothing industry's plight of no low-carbon alternative new material sources, and provide the textile industry with a solution to achieve the goal of net zero emissions in 2050. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acid%20dyes" title="acid dyes">acid dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeing" title=" dyeing"> dyeing</a>, <a href="https://publications.waset.org/abstracts/search?q=low-temperature" title=" low-temperature"> low-temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene%20fiber" title=" polypropylene fiber"> polypropylene fiber</a> </p> <a href="https://publications.waset.org/abstracts/165653/polypropylene-fibres-dyeable-with-acid-dyes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165653.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">349</span> Natural Dyeing of Textile Cotton Fabric and Its Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Almas">Rabia Almas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today’s world is demanding natural and biological colorants on priority bases as an alternative to toxic and unsustainable synthetic dyes. Sustainable natural colors from plants and/or living organisms such as bacteria's and fungi attracted the world research scholars and textile industries recently due to the excitement and opportunities they covered. So, in the present study, natural colors from food waste, such as orange peels and peanuts, were extracted and applied to cotton fabric. The dyeing recipes were optimized in terms of dye concentration, processing temperature and time for higher color strength. The characterization of the dyes and fabric, such as Fourier transform infrared spectroscopy, Scanning Electron Microscopy, and fastness properties were measured for the identification of the chemical groups involved for a better understanding of the dyeing behavior. The results revealed that proper mordanting and concentration of dye on cotton fabric could give high color strength and good fastness to wash and light and these natural dyes can be used as an alternative to synthetic toxic colorants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=textile" title="textile">textile</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20dyes" title=" textile dyes"> textile dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dyes" title=" natural dyes"> natural dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=bio%20colors" title=" bio colors"> bio colors</a> </p> <a href="https://publications.waset.org/abstracts/162104/natural-dyeing-of-textile-cotton-fabric-and-its-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162104.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">348</span> PMEL Marker Identification of Dark and Light Feather Colours in Local Canary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mudawamah%20Mudawamah">Mudawamah Mudawamah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Z.%20Fadli"> Muhammad Z.

The interesting phenomenon of the canary market is the feather colours become one of determining factor for the price. The advantages of this research were contributed to the molecular database as a base of selection and mating for the Indonesia canary breeder. The research method was experiment with the genome obtained from canary blood isolation. The genome did the PCR amplification with PMEL marker followed by sequencing. Canaries were used 24 heads of light and dark colour feathers. Research data analyses used BioEdit and Network 4.6.0.0 software. The results showed that all samples were amplification with PMEL gene with 500 bp fragment length. In base sequence of 40 was found Cytosine(C) in the light colour canaries, while the dark colour canaries was obtained Thymine (T) in same base sequence. Sequence results had 286-415 bp fragment and 10 haplotypes. The conclusions were the PMEL gene (gene of white pigment) was likely to be used PMEL gene to detect molecular genetic variation of dark and light colour feather. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canary" title="canary">canary</a>, <a href="https://publications.waset.org/abstracts/search?q=haplotype" title=" haplotype"> haplotype</a>, <a href="https://publications.waset.org/abstracts/search?q=PMEL" title=" PMEL"> PMEL</a>, <a href="https://publications.waset.org/abstracts/search?q=sequence" title=" sequence"> sequence</a> </p> <a href="https://publications.waset.org/abstracts/39620/pmel-marker-identification-of-dark-and-light-feather-colours-in-local-canary" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39620.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">347</span> Colour Formation and Maillard Reactions in Spray-Dried Milk Powders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelin%20Zhou">Zelin Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Langrish"> Timothy Langrish</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spray drying is the final stage of milk powder production. Traditionally, the quality of spray-dried milk powders has mainly been assessed using their physical properties, such as their moisture contents, while chemical changes occurring during the spray drying process have often been ignored. With growing concerns about food quality, it is necessary to establish a better understanding of heat-induced degradation due to the spray-drying process of skim milk. In this study, the extent of thermal degradation for skim milk in a pilot-scale spray dryer has been investigated using different inlet gas temperatures. The extent of heat-induced damage has been measured by the formation of advanced Maillard reaction products and the loss of soluble proteins at pH 4.6 as assessed by a fluorometric method. A significant increase in the extent of thermal degradation has been found when the inlet gas temperature increased from 170°C to 190°C, suggesting protein unfolding may play an important role in the kinetics of heat-induced degradation for milk in spray dryers. Colour changes of the spray-dried skim milk powders have also been analysed using a standard lighting box. Colourimetric analysis results were expressed in CIELAB colour space with the use of the E index (E) and the Chroma (C) for measuring the difference between colours and the intensity of the colours. A strong linear correlation between the colour intensity of the spray-dried skim milk powders and the formation of advanced Maillard reaction products has been observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colour%20formation" title="colour formation">colour formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Maillard%20reactions" title=" Maillard reactions"> Maillard reactions</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a>, <a href="https://publications.waset.org/abstracts/search?q=skim%20milk%20powder" title=" skim milk powder"> skim milk powder</a> </p> <a href="https://publications.waset.org/abstracts/120841/colour-formation-and-maillard-reactions-in-spray-dried-milk-powders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120841.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">346</span> Optimisation of Wastewater Treatment for Yeast Processing Effluent Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shepherd%20Manhokwe">Shepherd Manhokwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheron%20Shoko"> Sheron Shoko</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuthbert%20Zvidzai"> Cuthbert Zvidzai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the interactive effects of temperature and cultured bacteria on the performance of a biological treatment system of yeast processing wastewater were investigated.

However, few data are available on the effects of boiling temperatures and time on quality of the meat. In this study, colour, texture and sensory characteristics of Volutharpa ampullacea perryi meat during the boiling cooking processes (75-100 °C, 5-60 min) were investigated by colors analysis, texture profile analysis (TPA), scanning electron microscope (SEM) and sensory evaluation. The ratio of cooking loss gradually increased with the increase of temperature and time. The colour of meat became lighter and more yellower from 85 °C to 95 °C in a short time (5-20 min), but it became brown after a 30 min treatment. TPA results showed that the Volutharpa ampullacea perryi meat were more firm and less cohesive after a higher temperature (95-100 °C) treatment even in a short period (5-15 min). Based on the SEM analysis, it was easily found that the myofibrils structure was destroyed at a higher temperature (85-100 °C). Sensory data revealed that the meat cooked at 85-90 °C in 10-20 min showed higher scores in overall acceptance, as well as color, hardness and taste. Based on these results, it could be constructed that Volutharpa ampullacea perryi meat should be heated on a suitable condition (such as 85 °C 15 min or 90 °C 10 min) in the boiling cooking to be ensure a better acceptability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Volutharpa%20ampullacea%20perryi%20meat" title="Volutharpa ampullacea perryi meat">Volutharpa ampullacea perryi meat</a>, <a href="https://publications.waset.org/abstracts/search?q=boiling%20cooking" title=" boiling cooking"> boiling cooking</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory" title=" sensory"> sensory</a>, <a href="https://publications.waset.org/abstracts/search?q=texture" title=" texture"> texture</a> </p> <a href="https://publications.waset.org/abstracts/74170/effects-of-boiling-temperature-and-time-on-colour-texture-and-sensory-properties-of-volutharpa-ampullacea-perryi-meat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">281</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">344</span> Contribution of Electrochemical Treatment in Treating Textile Dye Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Usha%20N.%20Murthy">Usha N.

Considering both discharge volume and effluent composition, wastewater generated by the textile industry is rated as the most polluting among all industrial sectors. The pollution load is mainly due to spent dye baths, which are composed of unreacted dyes, dispersing agents, surfactants, salts and organics. In the present investigation, the textile dye wastewater was characterized by high colour, chemical oxygen demand (COD), total dissolved solids (TDS) and pH. Electrochemical oxidation process for four plate electrodes was carried out at five different current intensities, out of which 0.14A has achieved maximum percentage removal of COD with 75% and 83% of colour. The COD removal rate in kg COD/h/m2 decreases with increase in the current intensity. The energy consumption increases with increase in the current intensity. Hence, textile dye wastewater can be effectively pre-treated by electrochemical oxidation method where the process limits objectionable colour while leaving the COD associated with organics left for natural degradation thus causing a sustainable reduction in pollution load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20treatment" title="electrochemical treatment">electrochemical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=COD" title=" COD"> COD</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20engineering" title=" environmental engineering"> environmental engineering</a> </p> <a href="https://publications.waset.org/abstracts/6293/contribution-of-electrochemical-treatment-in-treating-textile-dye-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6293.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">278</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">343</span> Colorful Textiles with Antimicrobial Property Using Natural Dyes as Effective Green Finishing Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahid-ul-Islam">Shahid-ul-Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Faqeer%20Mohammad"> Faqeer Mohammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to investigate the effect of annatto, teak and flame of the forest natural dyes on color, fastness, and antimicrobial property of protein based textile substrate. The color strength (K/S) of wool samples at various concentrations of dyes were analysed using a Reflective Spectrophotometer. The antimicrobial activity of natural dyes before and after application on wool was tested against common human pathogens Escherichia coli, Staphylococcus aureus, and Candida albicans, by using micro-broth dilution method, disc diffusion assay and growth curve studies. The structural morphology of natural protein fibre (wool) was investigated by Scanning Electron Microscopy (SEM). Annatto and teak natural dyes proved very effective in inhibiting the microbial growth in solution phase and after application on wool and resulted in a broad beautiful spectrum of colors with exceptional fastness properties. The results encourage the search and exploitation of new plant species as source of dyes to replace toxic synthetic antimicrobial agents currently used in textile industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=annatto" title="annatto">annatto</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agents" title=" antimicrobial agents"> antimicrobial agents</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dyes" title=" natural dyes"> natural dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20textiles" title=" green textiles "> green textiles </a> </p> <a href="https://publications.waset.org/abstracts/42793/colorful-textiles-with-antimicrobial-property-using-natural-dyes-as-effective-green-finishing-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42793.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">342</span> The Colouration of Additive-Manufactured Polymer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abisuga%20Oluwayemisi%20Adebola">Abisuga Oluwayemisi Adebola</a>, <a href="https://publications.waset.org/abstracts/search?q=Kerri%20Akiwowo"> Kerri Akiwowo</a>, <a href="https://publications.waset.org/abstracts/search?q=Deon%20de%20Beer"> Deon de Beer</a>, <a href="https://publications.waset.org/abstracts/search?q=Kobus%20Van%20Der%20Walt"> Kobus Van Der Walt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The convergence of additive manufacturing (AM) and traditional textile dyeing techniques has initiated innovative possibilities for improving the visual application and customization potential of 3D-printed polymer objects. Textile dyeing techniques have progressed to transform fabrics with vibrant colours and complex patterns over centuries. The layer-by-layer deposition characteristic of AM necessitates adaptations in dye application methods to ensure even colour penetration across complex surfaces. Compatibility between dye formulations and polymer matrices influences colour uptake and stability, demanding careful selection and testing of dyes for optimal results. This study investigates the development interaction between these areas, revealing the challenges and opportunities of applying textile dyeing methods to colour 3D-printed polymer materials. The method explores three innovative approaches to colour the 3D-printed polymer object: (a) Additive Manufacturing of a Prototype, (b) the traditional dyebath method, and (c) the contemporary digital sublimation technique. The results show that the layer lines inherent to AM interact with dyes differently and affect the visual outcome compared to traditional textile fibers. Skillful manipulation of textile dyeing methods and dye type used for this research reduced the appearance of these lines to achieve consistency and desirable colour outcomes. In conclusion, integrating textile dyeing techniques into colouring 3D-printed polymer materials connects historical craftsmanship with innovative manufacturing. Overcoming challenges of colour distribution, compatibility, and layer line management requires a holistic approach that blends the technical consistency of AM with the artistic sensitivity of textile dyeing. Hence, applying textile dyeing methods to 3D-printed polymers opens new dimensions of aesthetic and functional possibilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer" title="polymer">polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=3D-printing" title=" 3D-printing"> 3D-printing</a>, <a href="https://publications.waset.org/abstracts/search?q=sublimation" title=" sublimation"> sublimation</a>, <a href="https://publications.waset.org/abstracts/search?q=textile" title=" textile"> textile</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeing" title=" dyeing"> dyeing</a>, <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title=" additive manufacturing"> additive manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/176518/the-colouration-of-additive-manufactured-polymer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">341</span> Morphological Properties of Soil Profile of Vineyard of Bangalore North (GKVK Farm), Karnataka, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harsha%20B.%20R.">Harsha B.

Water absorption and swelling capacities of the samples ranged from 0.89 to 1.80 ml/g and from 5.81 to 6.99 respectively. Pasting viscosity ranged from 870.33 RVU to 4660.67 RVU with the sample produced through the incorporation of full fat moringa seed flour during souring stage and 100% ogi flour having the least and highest values respectively. Stage of moringa seed inclusion also had effect on the trough, breakdown and final viscosity of the samples. The range of values obtained for these pasting parameters were 599.33-2940.00 RVU, 271.00-1720.67 RVU and 840.00-5451.67 RVU respectively. There was no significant difference (p≥ 0.05) in L*(a measure of whiteness) among the co fermented, blend of ogi and full fat moringa flours, blend of ogi and defatted moringa flour and 100% ogi flour samples.

The robust object boundaries detection in an image is demanded in numerous applications of human computer interaction and automated surveillance systems. Many methods and approaches have been developed for automatic object detection in various fields, such as automotive, quality control management and environmental services. Inappropriately, to the best of our knowledge, object detection under illumination with shadow consideration has not been well solved yet. Furthermore, this problem is also one of the major hurdles to keeping an object detection method from the practical applications. This paper presents an approach to automatic object detection in images under non-standardized environmental conditions. A key challenge is how to detect the object, particularly under uneven illumination conditions. Image capturing conditions the algorithms need to consider a variety of possible environmental factors as the colour information, lightening and shadows varies from image to image. Existing methods mostly failed to produce the appropriate result due to variation in colour information, lightening effects, threshold specifications, histogram dependencies and colour ranges. To overcome these limitations we propose an object detection algorithm, with pre-processing methods, to reduce the interference caused by shadow and illumination effects without fixed parameters. We use the Y CrCb colour model without any specific colour ranges and predefined threshold values. The segmented object regions are further classified using morphological operations (Erosion and Dilation) and contours. Proposed approach applied on a large image data set acquired under various environmental conditions for wood stack detection. Experiments show the promising result of the proposed approach in comparison with existing methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title="image processing">image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=illumination%20equalization" title=" illumination equalization"> illumination equalization</a>, <a href="https://publications.waset.org/abstracts/search?q=shadow%20filtering" title=" shadow filtering"> shadow filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20detection" title=" object detection"> object detection</a> </p> <a href="https://publications.waset.org/abstracts/77157/object-detection-in-digital-images-under-non-standardized-conditions-using-illumination-and-shadow-filtering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">338</span> Dyeing of Polyester/Cotton Blends with Reverse-Micelle Encapsulated High Energy Disperse/Reactive Dye Mixture </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Wai%20Kan">Chi-Wai Kan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanming%20%20Wang"> Yanming Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Yiu-Lun%20%20Tang"> Alan Yiu-Lun Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Hao%20Lee%20%20Lee"> Cheng-Hao Lee Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dyeing of polyester/cotton blend fabrics in various polyester/cotton percentages (32/68, 40/60 and 65/35) was investigated using (poly(ethylene glycol), PEG) based reverse-micelle.

Comparison of reverse micellar-based and aqueous-based (water-based) dyeing was conducted in terms of colour reflectance. Experimental findings revealed that the colour shade of the dyed fabrics in reverse micellar non-aqueous dyeing system at a lower dyeing temperature of 98°C is slightly lighter than that of conventional aqueous dyeing system in two-step process (130oC for disperse dyeing and 70°C for reactive dyeing).

This resource is not suitable for the production of decorative products, principally due to low grades of wood and “dull” appearance but many trials have been already undertaken for the production of veneer and veneer-based engineered wood products, such as plywood and laminated veneer lumber (LVL). The manufacture of veneer-based products has been recently identified as an unprecedented opportunity to promote higher value utilisation of plantation resources. However, many uncertainties remain regarding the impacts of inferior wood quality of young plantation trees on product recovery and value, and with respect to optimal processing techniques. Moreover, the quality of veneer and veneer-based products is far from optimal as trees are young and have small diameters; and the veneers have the significant colour variation which affects to the added value of final products. Developing production methods which would enhance appearance of low-quality veneer would provide a great potential for the production of high-value wood products such as furniture, joinery, flooring and other appearance products. One of the methods of enhancing appearance of low quality veneer, developed in Italy, involves the production of multilaminar veneer, also named “reconstructed veneer”. An important stage of the multilaminar production is colouring the veneer which can be achieved by dyeing veneer with dyes of different colours depending on the type of appearance products, their design and market demand. Although veneer dyeing technology has been well advanced in Italy, it has been focused on poplar veneer from plantation which wood is characterized by low density, even colour, small amount of defects and high permeability. Conversely, the majority of plantation eucalypts have medium to high density, have a lot of defects, uneven colour and low permeability. Therefore, detailed study is required to develop dyeing methods suitable for colouring eucalypt veneers. Brown reactive dye is used for veneer colouring process. Veneers from sapwood and heartwood of two moisture content levels are used to conduct colouring experiments: green veneer and veneer dried to 12% MC. Prior to dyeing, all samples are treated. Both soaking (dipping) and vacuum pressure methods are used in the study to compare the results and select most efficient method for veneer dyeing. To date, the results of colour measurements by CIELAB colour system showed significant differences in the colour of the undyed veneers produced from heartwood part. The colour became moderately darker with increasing of Sodium chloride, compared to control samples according to the colour measurements. It is difficult to conclude a suitable dye solution used in the experiments at this stage as the variables such as dye concentration, dyeing temperature or dyeing time have not been done. The dye will be used with and without UV absorbent after all trials are completed using optimal parameters in colouring veneers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eucalyptus%20globulus" title="Eucalyptus globulus">Eucalyptus globulus</a>, <a href="https://publications.waset.org/abstracts/search?q=veneer%20colouring%2Fdyeing" title=" veneer colouring/dyeing"> veneer colouring/dyeing</a>, <a href="https://publications.waset.org/abstracts/search?q=multilaminar%20veneer" title=" multilaminar veneer"> multilaminar veneer</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20dye" title=" reactive dye"> reactive dye</a> </p> <a href="https://publications.waset.org/abstracts/61643/mechanism-of-veneer-colouring-for-production-of-multilaminar-veneer-from-plantation-grown-eucalyptus-globulus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61643.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">336</span> Transparency Phenomenon in Kuew Teow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Heikal%20Ismail">Muhammad Heikal Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Law%20Chung%20Lim"> Law Chung Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hii%20Ching%20Lik"> Hii Ching Lik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In maintaining food quality and shelf life, drying is employed in food industry as the most reliable perseverance technique.

Therefore, we can see their appearance in many areas, such as storing web pages/websites, business phone numbers, redirecting to an app download, business location, social media. The popularity of the QR Code is mainly because of its many advantages, such as it can hold a good amount of information, is small, easy to scan and read by a general RGB camera, and it can still work with some damages on its surface. However, there are still some issues. For instance, some areas needed to be kept untouched for its successful decode (e.g., the “Finder Patterns,” the “Quiet Zone,” etc.), the capability of built-in auto-correction is not robust enough, and it is not flexible enough for many application such as Augment Reality (AR). We proposed a new Colour Quick Response Code that has several advantages over the original ones: (1) there is no untouchable area, (2) it allows up to 40% of the entire code area to be damaged, (3) it is more beneficial for Augmented Reality applications, and (4) it is back-compatible and readable by available QR Code scanners such as Pyzbar. From our experience, our Colour Quick Response Code is significantly more flexible on damage compared to the original QR Code. Our code is believed to be suitable in situations where standard 2D Barcodes fail to work, such as curved and shiny surfaces, for instance, medical blood test sample tubes and syringes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=QR%20code" title="QR code">QR code</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20barcode" title=" 2D barcode"> 2D barcode</a> </p> <a href="https://publications.waset.org/abstracts/148450/colour-quick-response-code-with-high-damage-resistance-capability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">334</span> Effectiveness of Jackfruit Seed Starch as Coagulant Aid in Landfill Leachate Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Suffian%20Yusoff">Mohd Suffian Yusoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Aina%20Mohamad%20Zuki"> Noor Aina Mohamad Zuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Faiz%20Muaz%20Ahmad%20Zamri"> Mohd Faiz Muaz Ahmad Zamri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, aluminium sulphate (alum), ferric chloride and polyaluminium chloride (PAC) are the most common coagulants being used for leachate coagulation-flocculation treatment. However, the impact of these residual’s coagulants have sparked huge concern ceaselessly. Therefore, development of natural coagulant as an alternative coagulant for treatment process has been given full attentions. In this attempt jackfruit seed starch (JSS) was produce by extraction method. The removal efficiency was determined using jar test method. The removal of organic matter and ammonia were compared between JSS used in powder form and diluted form in leachate. The yield of starch from the extraction method was 33.17 % with light brown in colour. The removal of turbidity was the highest at pH 8 for both diluted and powdered JSS with 38% and 8.7% of removal. While for colour removal the diluted JSS showed 18.19% of removal compared to powdered JSS. The diluted JSS also showed the highest removal of suspended solid with 3.5% compared to powdered JSS with 2.8%. Instead of coagulant, JSS as coagulant aid has succeed to reduce the dosage of PAC from 900 mg/L to 528 mg/L by maintaining colour and turbidity removal up to 94% and 92 % respectively. The JSS coagulant also has decreased the negative charge of the leachate nearly to the neutral charge (0.209 mv). The result proved that JSS was more effective to be used as coagulant aid landfill leachate treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landfill%20leachate" title="landfill leachate">landfill leachate</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20coagulant" title=" natural coagulant"> natural coagulant</a>, <a href="https://publications.waset.org/abstracts/search?q=jackfruit%20seed%20starch" title=" jackfruit seed starch"> jackfruit seed starch</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulant" title=" coagulant"> coagulant</a> </p> <a href="https://publications.waset.org/abstracts/17307/effectiveness-of-jackfruit-seed-starch-as-coagulant-aid-in-landfill-leachate-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17307.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">504</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">333</span> A Comparative Study on the Phenolics Composition and Antioxidant Properties of Water Yam Landraces in Kerala, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anumol%20Jose">Anumol Jose</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajana%20Nazar"> Sajana Nazar</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Vishnu"> M.

There is an inverse relationship between the risk of chronic human diseases and the consumption of polyphenolic rich diet. Dioscorea alata is a plant species with several undocumented landraces. In this study, several landraces of water yam with distinct morphological features were collected from all over kerala. Distinct variation in morphological feature among landraces was tuber colour and only those landraces which expressed consistent morphological characters for constitutively two growing seasons were included in the study. Plants were categorized according to the L*a*b* colour attributes of tuber extracts. There were five categories, red, pink, orange, yellow and white. Total phenol, flavanoid and anthocyanin content of the tuber extracts were measured spectroscopically and correlated with antioxidant properties determined by 2,2-diphenyl-1-picryl-hydrazyl-hydrate free radical method and ferric reducing antioxidant power assay. Landraces showed statistically significant difference in all the parameters studied and strong correlation were observed between total phenol and antioxidant activity. Out of the five categories orange coloured tubers showed relatively high phenol and flavanoid content.Colour variations of tuber extracts correlated with anthocyanin quantity and polymeric nature of anthocyanins. This study helps to identify and categorize landraces of D.alata with potential health benefits and commercial applications. Distinct colour characteristics of tuber could be useful in the field of natural colorants. This study also aimed to document and preserve landraces of water yams for further study and research in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20antioxidant%20property" title="the antioxidant property">the antioxidant property</a>, <a href="https://publications.waset.org/abstracts/search?q=anthocyanins" title=" anthocyanins"> anthocyanins</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20yam" title=" water yam"> water yam</a> </p> <a href="https://publications.waset.org/abstracts/97322/a-comparative-study-on-the-phenolics-composition-and-antioxidant-properties-of-water-yam-landraces-in-kerala-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">332</span> Indian Brands Speak Through Colors That Is ‘Culturally Vibrant’</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ranjana%20Dani">Ranjana Dani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brand communication narratives in India has evolved today to reflect the vibrant and intriguing tone of voice inspired by a rich cultural heritage while addressing the culturally alert attitude of the contemporary global Indian. Brands are strongly associated with the organization's values, vision, and mission and portray this through specific ‘look and feel’ and ‘tone of voice’. It is within the brand’s visual language that COLOUR has evolved to become a most powerful weapon in the designer’s arsenal. Color is big business in Brand Design! A brand is a ‘collection of perceptions’, meaningful brand connect is about striving to occupy head and heart space in consumers. The persona of the young Indian reflects a deep attachment to cultural roots as seen through the characteristic of ‘Indie Pride,’ blended with the ambitious, aspirational traits of a modern ‘global citizen’.Studies on ‘Color Perceptions’ indicate a trend that amplifies this, and hence brands reflect a GLOCAL palette, a Global and Local Blend. This paper establishes this through case studies that expand the inspirations, selection processes, and use of innovative color palettes crafted by some dynamic brand designers. This throws light on the role of color as it generates visual impact and recall for successful brands. <p class="card-text"><strong>Keywords:</strong> <a
