extraction has attracted great interest among the researchers. The main virtue of the microwave technique is cost-effective, time saving and simple handling procedure. Castor beans was chosen because of its high content in fatty acid, especially ricinoleic acid. The purpose of this research is to extract the castor oil by using the microwave assisted extraction (MAE) using ethanol as solvent and to investigate the influence of extraction time on castor oil yield and to characterize the main composition of the produced castor oil by using the GC-MS. It was found that there is a direct dependence between the oil yield and the time of extraction as it increases from 45% to 58% as the time increase from 10 min to 60 min. The major components of castor oil detected by GC-MS were ricinoleic acid, linoleic acid and oleic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microwave%20assisted%20extraction%20%28MAE%29" title="microwave assisted extraction (MAE)">microwave assisted extraction (MAE)</a>, <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title=" castor oil"> castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=ricinoleic%20acid" title=" ricinoleic acid"> ricinoleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=linoleic%20acid" title=" linoleic acid"> linoleic acid</a> </p> <a href="https://publications.waset.org/abstracts/10844/microwave-assisted-extraction-mae-of-castor-oil-from-castor-bean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10844.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">503</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">193</span> Effects of Different Sowing Dates on Oil Yield of Castor (Ricinus communis L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zden%20%C3%96zt%C3%BCrk">Özden Öztürk</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6zde%20P%C4%B1nar%20Gerem"> Gözde Pınar Gerem</a>, <a href="https://publications.waset.org/abstracts/search?q=Ay%C3%A7a%20Yenici"> Ayça Yenici</a>, <a href="https://publications.waset.org/abstracts/search?q=Burcu%20Haspolat"> Burcu Haspolat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Castor (Ricinus communis L.) is one of the important non-edible oilseed crops having immense industrial and medicinal value. Oil yield per unit area is the ultimate target in growing oilseed plants and sowing date is one of the important factors which have a clear role in the production of active substances particularly in oilseeds. This study was conducted to evaluate the effect of sowing date on the seed and oil yield of castor in Central Anatolia in Turkey in 2011. The field experiment was set up in a completely randomized block design with three replication. Black Diamond-2 castor cultivar was used as plant material. The treatment was four sowing dates of May 10, May 25, June 10, June 25. In this research; seed yield, oil content and oil yield were investigated. Results showed that the effect of different sowing dates was significant on all of the characteristics. In general; delayed sowing dates, resulted in decreased seed yield, oil content and oil yield. The highest value of seed yield, oil content and oil yield (respectively, 2523.7 kg ha-1, 51.18% and 1292.2 kg ha-1) were obtained from the first sowing date (May 10) while the lowest seed yield, oil content and oil yield (respectively, 1550 kg ha-1, 43.67%, 677.3 kg ha-1) were recorded from the latest sowing date (June 25). Therefore, it can be concluded that early May could be recommended as an appropriate sowing date in the studied location and similar climates for achieved high oil yield of castor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20bean" title="castor bean">castor bean</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricinus%20communis%20L." title=" Ricinus communis L."> Ricinus communis L.</a>, <a href="https://publications.waset.org/abstracts/search?q=sowing%20date" title=" sowing date"> sowing date</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20yield" title=" seed yield"> seed yield</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20content" title=" oil content"> oil content</a> </p> <a href="https://publications.waset.org/abstracts/2642/effects-of-different-sowing-dates-on-oil-yield-of-castor-ricinus-communis-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2642.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">383</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">192</span> RAPD Analysis of Genetic Diversity of Castor Bean</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Vivod%C3%ADk">M.

Leaf samples from castor bean plants with leaf curl and vein thickening were collected from areas around Okara (Pakistan) in 2011. PCR amplification using diagnostic primers showed the presence of a begomovirus and subsequently the specific pair (BurNF 5’- CCATGGTTGTGGCAGTTGATTGACAGATAC-3’, BurNR 5’- CCATGGATTCACGCACAGGGGAACCC-3’) was used to amplify and clone the whole genome of the virus. The complete nucleotide sequence was determined to be 2,759 nt (accession No. HE985227). Alignments showed the highest levels of nucleotide sequence identity (98.8%) with Cotton leaf curl Burewala virus (CLCuBuV; accession No. JF416947) No. JF416947). The virus in castor beans lacks on intact C2 gene, as is typical of CLCuBuV in cotton. An amplification product of ca. 1.4 kb was obtained in PCR with primers for betasatellites and the complete nucleotide sequence of a clone was determined to be 1373 nt (HE985228). The sequence showed 96.3% nucleotide sequence identity to the recombinant Cotton leaf curl Multan betasatellite (CLCuMB; JF502389). This is the first report of CLCuBuV and its betasatellite infecting castor bean, showing this plant species as an alternate host of the virus. Already many alternate host have been reported from different alternate host like tobacco, tomato, hibiscus, okra, ageratum, Digera arvensis, habiscus, Papaya and now in Ricinus communis. So, it is suggested that these alternate hosts should be avoided to grow near cotton growing regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricinus%20communis" title="Ricinus communis">Ricinus communis</a>, <a href="https://publications.waset.org/abstracts/search?q=begomovirus" title=" begomovirus"> begomovirus</a>, <a href="https://publications.waset.org/abstracts/search?q=betasatellite" title=" betasatellite"> betasatellite</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a> </p> <a href="https://publications.waset.org/abstracts/21282/isolation-and-characterization-of-cotton-infecting-begomoviruses-in-alternate-hosts-from-cotton-growing-regions-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21282.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">531</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">190</span> Potential of Castor Bean (Ricinus Communis L.) for Phytoremediation of Soils Contaminated with Heavy Metals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Violina%20Angelova">Violina Angelova</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Perifanova-Nemska"> Mariana Perifanova-Nemska</a>, <a href="https://publications.waset.org/abstracts/search?q=Krasimir%20Ivanov"> Krasimir Ivanov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research was to investigate the potential for the use of Ricinus communis L. (castor oil plant) to remediate metal-polluted sites. This study was performed in industrially polluted soils containing high concentrations of Zn, Pb and Cd, situated at different distances (0.3, 2.0 and 15.0 km) from the source of pollution - the Non-Ferrous Metal Works near Plovdiv, Bulgaria. On reaching commercial ripeness, the castor oil plants were gathered and the contents of heavy metals in their different parts – roots, stems, leaves and seeds, were determined after dry ashing. Physico-chemical characterization, total, DTPA extractable and water-soluble metals in rhizospheric soil samples were carried. Translocation factors (TFs) were also determined. The quantitative measurements were carried out with ICP. A soxhlet extraction was used for the extraction of the oil, using hexane as solvent. The oil was recovered by simple distillation of the solvent. The residual oil obtained was investigated for physicochemical parameters and fatty acid composition. Bioaccumulation factor and translocation factor values (BAF and TF > 1) were greater than one suggesting efficient accumulation in the shoot. The castor oil plant may be preferred as a good candidate for phytoremediation (phytoextraction). These results indicate that R. communis has good potential for removing Pb from contaminated soils attributed to its fast growth, high biomass, strong absorption and accumulation for Pb. The concentrations of heavy metals in the oil were low as seed coats accumulated the highest concentrations of Cd and Pb. In addition, the result of the fatty acid composition analysis confirms the oil to be of good quality and can be used for industrial purposes such as cosmetics, soaps and paint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20bean" title="castor bean">castor bean</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title=" phytoremediation"> phytoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=polluted%20soils" title=" polluted soils"> polluted soils</a> </p> <a href="https://publications.waset.org/abstracts/42571/potential-of-castor-bean-ricinus-communis-l-for-phytoremediation-of-soils-contaminated-with-heavy-metals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42571.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">241</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">189</span> Chemical and Sensorial Evaluation of a Newly Developed Bean Jam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raquel%20P.%20F.%20Guin%C3%A9">Raquel P.

Three different jams were produced: bean and carrot, bean and apple and bean, apple and cinnamon. The developed products underwent a sensorial analysis that revealed that the bean, apple and cinnamon jam was globally better accepted. However, with this study, the consumers determined that the bean and carrot jam had the most attractive color and the bean and apple jam the better consistency. Additionally, it was possible to analyze the jams for their chemical components, namely fat, fiber, protein, sugars and antioxidant activity. The obtained results showed that the bean and carrot jam had the highest lipid content, while the bean, apple and cinnamon jam had the highest fiber content, when compared to the other two jams. Regarding the sugar content, both jams with apple revealed similar sugar values, which were higher than the sugar content of the bean and carrot jam.

For this purpose, different plant oils such as soybean oil, castor oil and linseed oil are extensively used. Moreover, the isocyanate used for the synthesis of polyurethane is derived from petroleum resources. In this present work attempts have been made for the successful synthesis of biobased isocyanate from castor oil with partially biobased isocyanate in presence of catalyst dibutyltin dilaurate (DBTDL). The goal of the present study was to investigate the thermal, mechanical, morphological and chemical properties of the synthesized polyurethane in terms of castor oil modification. The transesterified polyol shows broad and higher hydroxyl value as compared to castor oil which was confirmed by FTIR studies. The FTIR studies also revealed the successful synthesis of bio based polyurethane by showing characteristic peaks at 3300cm-1, 1715cm-1 and 1532cm-1 respectively. The TGA results showed three step degradation mechanism for the synthesized polyurethane from modified and unmodified castor oil. However, the modified polyurethane exhibited higher degradation temperature as compared to unmodified one. The mechanical properties also demonstrated higher tensile strength for modified polyurethane as compared to unmodified one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title="castor oil">castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=partially%20biobased%20Isocyanate" title=" partially biobased Isocyanate"> partially biobased Isocyanate</a>, <a href="https://publications.waset.org/abstracts/search?q=polyurethane%20synthesis" title=" polyurethane synthesis"> polyurethane synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a> </p> <a href="https://publications.waset.org/abstracts/20628/biobased-polyurethane-derived-from-transesterified-castor-oil-synthesis-and-charecterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20628.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">352</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">187</span> Bioethanol Synthesis Using Cellulose Recovered from Biowaste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Faisal%20Najmuldeen">Ghazi Faisal Najmuldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Noridah%20Abdullah"> Noridah Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mimi%20Sakinah"> Mimi Sakinah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bioethanol is an alcohol made by fermentation, mostly from carbohydrates, Cellulosic biomass, derived from non-food sources, such as castor shell waste, is also being developed as a feedstock for ethanol production Cellulose extracted from biomass sources is considered the future feedstock for many products due to the availability and eco-friendly nature of cellulose.

The pretreatment process began with the removal of other extractives from CS, then an alkaline treatment, bleaching process with hydrogen peroxide, and followed by a mixture of acetic and nitric acids. CS cellulose was analysed by infrared absorption spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The result showed that the overall process was adequate to produce cellulose with high purity and crystallinity from CS waste. The cellulose was then hydrolyzed to produce glucose and then fermented to bioethanol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioethanol" title="bioethanol">bioethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=castor%20shell" title=" castor shell"> castor shell</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose" title=" cellulose"> cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=biowaste" title=" biowaste"> biowaste</a> </p> <a href="https://publications.waset.org/abstracts/45623/bioethanol-synthesis-using-cellulose-recovered-from-biowaste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45623.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">233</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">186</span> Comparative Analysis of White Bean Cake and Soybean Cake through Sensory Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ijeoma%20Chinyere%20Ukonu">Ijeoma Chinyere Ukonu</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Ojeyokan"> Linda Ojeyokan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study produced and compared the acceptability of white bean cake (akara) and soy bean cake (akara) through sensory evaluation. Two varieties of beans were used; white (haricot) beans and soy beans; processed in the wet (paste) form and dry (flour) form. They were all used in the production of samples of bean cake (akara) under the same condition. Sensory evaluation was carried out on the products; 100% white beans cake paste was labeled (A1), 50% white bean and 50% soya bean cake paste was (B1), 100% white bean cake flour was (A2); 50% white bean cake flour and 50% soya bean cake flour (B2). A five (5) point hedonic scale rating, very good (5), good (4), fair (3), poor (2) and very poor (1) was administered on the ten panel of judge. 40 questionnaires were administered to the general public to access their knowledge of soya beans akara. Correlation analysis was carried out to determine which product is more acceptable. Table, percentages and mean score were methods employed in analyzing data collected. The analysis revealed that soya bean (akara) is generally acceptable except for sample B1 that was rated poor with 2 points, white beans cake was rated very well with 5 points. It was recommended that the hospitality industry could introduce soya bean cakes in the breakfast menu. Families can also include these products in their breakfast. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=akara" title="akara">akara</a>, <a href="https://publications.waset.org/abstracts/search?q=bean%20cake" title=" bean cake"> bean cake</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20bean" title=" white bean "> white bean </a> </p> <a href="https://publications.waset.org/abstracts/54338/comparative-analysis-of-white-bean-cake-and-soybean-cake-through-sensory-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54338.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">267</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">185</span> Utilization of Sorghum and White Bean Flour for the Production of Gluten Free and Iron Rich Cookies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahra%20Elobeid">Tahra Elobeid</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmerich%20Berghofer"> Emmerich Berghofer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to find innovative approaches for the production of iron rich foods using natural iron sources. The vehicle used for fortification was sorghum whereas the iron fortificant was white bean. Fortified sorghum cookies were produced from five different mixtures; iron content, iron bioavailability, cookie texture and acceptability were measured. Cookies were prepared from the three fortified flours; 90% sorghum + 10% white bean (S9WB1), 75% sorghum + 25% white bean (S3WB1), 50% sorghum + 50% white bean (S1WB1) and 100% sorghum and 100% white bean. The functional properties gave good results in all the formulations. Statistical analysis of the iron content in the five different cookies showed that there was significant difference at the 95% confidence level (ANOVA). The iron content in all the recipes including the 100% sorghum improved, the increase ranging from 112% in 100% sorghum cookies to 476% in 100% white bean cookies. This shows that the increase in the amount of white bean used for fortification leads to the improvement of the iron content of cookies. The bioavailability of iron ranged from 21.3% in 100% sorghum to 28.6% in 100% white bean cookies. In the 100% sorghum cookies the iron bioavailability increased with reference to raw sorghum due to the addition of eggs. Bioavailability of iron in raw sorghum is 16.2%, therefore the percentage increase ranged from 5.1% to 28.6%. The cookies prepared from 10% white bean (S9WB1) scored the lowest 3.7 in terms of acceptability. They were the least preferred due to their somewhat soft texture. The 30% white bean cookies (S3WB1) gave results comparable to the 50% (S1WB1) and 100% white bean cookies. Cookies prepared with high percentage of white bean (50% and 100% white bean) gave the best results. Therefore cookie formulations from sorghum and white bean are successful in improving the iron status of anaemic individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sorghum" title="sorghum">sorghum</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20bean" title=" white bean"> white bean</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20content" title=" iron content"> iron content</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailable%20iron" title=" bioavailable iron"> bioavailable iron</a>, <a href="https://publications.waset.org/abstracts/search?q=cookies" title=" cookies"> cookies</a> </p> <a href="https://publications.waset.org/abstracts/18687/utilization-of-sorghum-and-white-bean-flour-for-the-production-of-gluten-free-and-iron-rich-cookies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18687.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">414</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">184</span> Relaxation Behavior of Biorenewable Waterborne Castor Oil-Based Polyurethane-Lignin Thin Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samy%20Madbouly">Samy Madbouly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relaxation behavior of biorenewable castor oil-based polyurethane-lignin thin films synthesized in homogenous waterborne dispersions was investigated as a function of concentration at different temperatures and frequencies using broadband dielectric relaxation spectroscopy (BDRS). The molecular dynamics of the glass relaxation process and the local relaxation process of the PU-LS thin films were studied over a wide range of temperatures (-70 to 30 ℃) and frequencies (5 × 10−2 to 0.5 × 107 Hz) for different lignin concentration. Four relaxation processes have been observed namely; ?-, β-, γ-relaxations and ionic conductivity for pure castor oil-based PU and castor oil-lignin-based PU thin films at different temperatures and frequencies ranges. The Vogel-Fulcher-Tammann equation was found to be well described the temperature dependence of the characteristic relaxation times of the ?-relaxation process. However, on the other hand, the molecular dynamics of both β- and γ-relaxation processes were given by the Arrhenius equation. The incorporation of lignin into the castor oil-based PU significantly increased the glass transition temperature and primitivity of the thin films. In addition, the broadness, intensity, and molecular dynamics of the only observed ?-relaxation process were found to be strongly dependent on lignin concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title="castor oil">castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=lignin" title=" lignin"> lignin</a>, <a href="https://publications.waset.org/abstracts/search?q=polyurethane" title=" polyurethane"> polyurethane</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric" title=" dielectric"> dielectric</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersions" title=" dispersions"> dispersions</a> </p> <a href="https://publications.waset.org/abstracts/140796/relaxation-behavior-of-biorenewable-waterborne-castor-oil-based-polyurethane-lignin-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140796.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">204</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">183</span> Microwave Assisted Thermal Cracking of Castor Oil Zeolite ZSM-5 as Catalyst for Biofuel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Faisal%20Najmuldeen">Ghazi Faisal Najmuldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Abdul%20Rahman%E2%80%93Al%20Ezzi"> Ali Abdul Rahman–Al Ezzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tharmathas%20A%2FL%20Alagappan"> Tharmathas A/L Alagappan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this investigation was to produce biofuel from castor oil through microwave assisted thermal cracking with zeolite ZSM-5 as catalyst. The obtained results showed that microwave assisted thermal cracking of castor oil with Zeolite ZSM-5 as catalyst generates products consisting of alcohol, methyl esters and fatty acids. The products obtained from this experimental procedure by the cracking of castor oil are components of biodiesel. Samples of cracked castor oil containing 1, 3 and 5wt % catalyst was analyzed, however, only the sample containing the 5wt % catalyst showed significant presence of condensate. FTIR and GCMS studies show that the condensate obtained is an unsaturated fatty acid, is 9, 12-octadecadienoic acid, suitable for biofuel use. 9, 12-octadecadienoic acid is an unsaturated fatty acid with a molecular weight of 280.445 g/mol. Characterization of the sample demonstrates that functional group for the products from the three samples display a similar peak in the FTIR graph analysis at 1700 cm-1 and 3600 cm-1. The result obtained from GCMS shows that there are 16 peaks obtained from the sample. The compound with the highest peak area is 9, 12-octadecadienoic acid with a retention time of 9.941 and 24.65 peak areas. All these compounds are organic material and can be characterized as biofuel and biodiesel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title="castor oil">castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuel" title=" biofuel"> biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title=" biodiesel"> biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20cracking" title=" thermal cracking"> thermal cracking</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave" title=" microwave"> microwave</a> </p> <a href="https://publications.waset.org/abstracts/39975/microwave-assisted-thermal-cracking-of-castor-oil-zeolite-zsm-5-as-catalyst-for-biofuel-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39975.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">232</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">182</span> Assessment of Relationships between Agro-Morphological Traits and Cold Tolerance in Faba Bean (vicia faba l.) and Wild Relatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisa%20Ertoy%20Inci">Nisa Ertoy Inci</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Toker"> Cengiz Toker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Winter or autumn-sown faba bean (Vicia faba L.) is one the most efficient ways to overcome drought since faba bean is usually grown under rainfed where drought and high-temperature stresses are the main growth constraints. The objectives of this study were assessment of (i) relationships between cold tolerance and agro-morphological traits, and (ii) the most suitable agro-morphological trait(s) under cold conditions. Three species of the genus Vicia L. includes 109 genotypes of faba bean (Vicia faba L.), three genotypes of narbon bean (V. narbonensis L.) and two genotypes of V. montbretii Fisch. & C.A. Mey. Davis and Plitmann were sown in autumn at highland of Mediterranean region of Turkey. All relatives of faba bean were more cold-tolerant than the faba bean genotypes. Three faba bean genotypes, ACV-42, ACV-84 and ACV-88, were selected as sources of cold tolerance under field conditions. Path and correlation coefficients and factor and principal component analyses indicated that biological yield should be evaluated in selection for cold tolerance under cold conditions ahead of many agro-morphological traits.

Curing time has been studied by observing at the time of reaction, which can be confirmed by AT-FTIR. DSC has been studied to monitor the reaction between CO & Isocyanates using non Isothermal process. Curing kinetics have also been studied to investigate the catalytic effect of the NCO / OH ratio of Polyurethane. Adhesion properties were evaluated from Lapshear test. Tg of the PU polymer was evaluated by DSC which can be compared by DMA. Surface Properties were studied by contact angle measurement.

This gap stifles initiatives on the evaluation of the suitability of the methods used and the invention of new and better methods. The study; therefore, assesses activities of processors in domestication/conservation and processing of oil bean (Pentaclethra macrophylla) Enugu State, South East Nigeria. Three agricultural zones, three blocks, nine circles and seventy-two respondents that were purposively selected made up the sample for the study. Data were presented in percentage, chart and mean score. The result shows that processors of oil bean in the area were middle-aged, married with relatively large household size and long years of experience in processing. They sourced oil bean they processed from people’s farmland and sourced information on processing of oil bean from friends and relatives. Activities involved in processing of oil bean were boiling, dehulling, washing, sieving, slicing, wrapping. However, the sequence of these activities varies among these processors. Little or nothing was done by the processors towards the conservation of the crop while poor storage and processing facilities and lack of knowledge on modern preservation technique were major constraints to processing of oil bean in the area. The study concluded that efforts should be made by governments and processors through cooperative group in provision of processing and storage facility for oil bean while research institute should conserve and generate improved specie of the crop to arouse interest of the farmers and processors on the crop which will invariably increase productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation" title="conservation">conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=domestication" title=" domestication"> domestication</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20bean" title=" oil bean"> oil bean</a>, <a href="https://publications.waset.org/abstracts/search?q=processing" title=" processing"> processing</a> </p> <a href="https://publications.waset.org/abstracts/27406/activities-of-processors-in-domesticationconservation-and-processing-of-oil-bean-pentaclethra-macrophylla-in-enugu-state-south-east-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27406.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">308</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">176</span> Synthesis of Epoxidized Castor Oil Using a Sulphonated Polystyrene Type Cation Exchange Resin and Its Blend Preparation with Epoxy Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20S.%20Sudha">G.

Larval duration during spring season was maximum in all strains in all food plants; however minimum for all strains was recorded during summer season on Castor, Kesseru and Tapioca. Cocoon weight was recorded to be minimum (2.8 ± 2 0.55 gm) in YP on Kesseru and maximum (4.06 ± 0.68 gm) in GBZ on Castor during spring season; shell weight fluctuated between 0.34 ± 0.08 gm during spring in GBS on Kesseru and 0.58 ± 0.09 gm during summer in YZ on Castor and percentage of silk ratio was found to be minimum and maximum in YP on Payam during spring (11.37 ± 1.29) and in GBS on Castor during summer (16.05 ± 1.59) respectively. The variation in larval duration and cocoon parameters reflected variation in nutrient composition of food plants and dynamic environment conditions prevailing in different seasons of the year. Payam and Tapioca plants could be fed either singly or alternately with Castor or Kesseru to attain the commercial advantage to ensure more value added production. While there were differences in the productivity parameters with respect to strains and seasons, the present study shows that all the strains on four host plants expressed adaptability and suitability for commercial rearing under Nagaland climatic condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20food%20plants" title="alternative food plants">alternative food plants</a>, <a href="https://publications.waset.org/abstracts/search?q=Larval%20and%20cocoon%20parameters" title=" Larval and cocoon parameters"> Larval and cocoon parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=Nagaland%20Inia" title=" Nagaland Inia"> Nagaland Inia</a>, <a href="https://publications.waset.org/abstracts/search?q=six%20strains%20of%20Samia%20ricini" title=" six strains of Samia ricini"> six strains of Samia ricini</a> </p> <a href="https://publications.waset.org/abstracts/55798/effect-of-varietal-feeding-on-larval-duration-and-cocoon-parameters-of-six-strains-of-eri-silkworm-samia-ricini-donovan-in-nagaland-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55798.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">209</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">174</span> Different Tillage Possibilities for Second Crop in Green Bean Farming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yilmaz%20Bayhan">Yilmaz Bayhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20G%C3%BCzel"> Emin Güzel</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Bar%C4%B1%C5%9F%20%C3%96zl%C3%BCoymak"> Ömer Barış Özlüoymak</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20%C4%B0nce"> Ahmet İnce</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Sessiz"> Abdullah Sessiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, determining of reduced tillage techniques in green bean farming as a second crop after harvesting wheat was targeted. To this aim, four different soil tillage methods namely, heavy-duty disc harrow (HD), rotary tiller (ROT), heavy-duty disc harrow plus rotary tiller (HD+ROT) and no-tillage (NT) (seeding by direct drill) were examined. Experiments were arranged in a randomized block design with three replications. The highest green beans yields were obtained in HD+ROT and NT as 5,862.1 and 5,829.3 Mg/ha, respectively. The lowest green bean yield was found in HD as 3,076.7 Mg/ha. The highest fuel consumption was measured 30.60 L ha<sup>-1 </sup>for HD+ROT whereas the lowest value was found 7.50 L ha<sup>-1</sup> for NT. No tillage method gave the best results for fuel consumption and effective power requirement. It is concluded that no-tillage method can be used in second crop green bean in the Thrace Region due to economic and erosion conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20bean" title="green bean">green bean</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20tillage" title=" soil tillage"> soil tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetative" title=" vegetative"> vegetative</a> </p> <a href="https://publications.waset.org/abstracts/68586/different-tillage-possibilities-for-second-crop-in-green-bean-farming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68586.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">373</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">173</span> The Effects of Drying Technology on Rehydration Time and Quality of Mung Bean Vermicelli</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20P.%20Tien">N.

The preparation process involves several steps, including drying, which affects the structure and quality of the vermicelli. This study aims to examine the effects of different drying technologies on the rehydration time and quality of mung bean vermicelli. Three drying technologies, namely hot air drying, microwave continuous drying, and microwave vacuum drying, were used for the drying process. The vermicelli strands were dried at 45°C for 12h in a hot air dryer, at 70 Hz of conveyor belt speed inverter in a microwave continuous dryer, and at 30 W.g⁻¹ of microwave power density in a microwave vacuum dryer. The results showed that mung bean vermicelli dried using hot air drying had the longest rehydration time of 12.69 minutes. On the other hand, vermicelli dried through microwave continuous drying and microwave vacuum drying had shorter rehydration times of 2.79 minutes and 2.14 minutes, respectively. Microwave vacuum drying also resulted in larger porosity, higher water absorption, and cooking loss. The tensile strength and elasticity of vermicelli dried using hot air drying were higher compared to microwave drying technologies. The sensory evaluation did not reveal significant differences in most attributes among the vermicelli treatments. Overall, microwave drying technology proved to be effective in reducing rehydration time and producing good-quality mung bean vermicelli. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mung%20bean%20vermicelli" title="mung bean vermicelli">mung bean vermicelli</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20air" title=" hot air"> hot air</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20continuous" title=" microwave continuous"> microwave continuous</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20vacuum" title=" microwave vacuum"> microwave vacuum</a> </p> <a href="https://publications.waset.org/abstracts/170532/the-effects-of-drying-technology-on-rehydration-time-and-quality-of-mung-bean-vermicelli" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170532.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">79</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">172</span> The Effect of Fermentation and Germination on the Nutrient and Antinutrient Composition of Lima Bean (Phaseolus lunatus) Flour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20N.%20Okeke">P.

In this study, the influence of fermentation and germination on the chemical properties of Lima bean (Phaseolus lunatus) flour were evaluated. The flours were analyzed for their proximate and mineral composition, using the standard assay methods. The result showed that fermentation and germination increased the moisture, protein and ash content of the flours while fiber, fat and carbohydrate were decreased. The protein level of fermented and germinated lima bean increased from 21.06–26.60%. The minerals: iron, copper, zinc, and phosphorous increased due to germination and fermentation. The phytate and tannin levels were drastically reduced in both the fermented and germinated flours. The result of this study revealed that fermentation and germination makes the nutrient in lima beans more accessible as it reduces the anti-nutrients. It is therefore recommended that lima bean be process accordingly for richer and more bio-availability of the nutrients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient" title="nutrient">nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-nutrient" title=" anti-nutrient"> anti-nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=fermented" title=" fermented"> fermented</a>, <a href="https://publications.waset.org/abstracts/search?q=germinated" title=" germinated"> germinated</a>, <a href="https://publications.waset.org/abstracts/search?q=lima%20bean%20flour" title=" lima bean flour "> lima bean flour </a> </p> <a href="https://publications.waset.org/abstracts/22168/the-effect-of-fermentation-and-germination-on-the-nutrient-and-antinutrient-composition-of-lima-bean-phaseolus-lunatus-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22168.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">390</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">171</span> In situ Polymerization and Properties of Biobased Polyurethane/Epoxy Interpenetrating Network Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aiswarea%20Mathew">Aiswarea Mathew</a>, <a href="https://publications.waset.org/abstracts/search?q=Smita%20Mohanty"> Smita Mohanty</a>, <a href="https://publications.waset.org/abstracts/search?q=Jr."> Jr.</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Nayak"> S.

Polyurethane/epoxy resin interpenetrating network nanocomposites containing modified montmorillonite organoclay (C30B-PU/EP nanocomposites) were prepared by an in situ intercalation method. The conventional spectroscopic characterization of the synthesized samples using FT-IR confirms the existence of the proposed castor oil based PU structure and also showed that strong interactions existed between C30B and EP/PU matrix. The dispersion degree of C30B in EP/PU matrix was characterized by X-Ray diffraction (XRD) method. Scanning electronic microscopy analysis showed that the interpenetrating process of PU and EP increases the exfoliation degree of C30B, and it improves the compatibility and the phase structure of polyurethane/epoxy resin interpenetrating polymer networks (PU/EP IPNs). The thermal stability improves compared to the polyurethane when the PU/EP IPN is formed. Mechanical properties including the Young’s modulus and tensile strength reflected marked improvement with addition of C30B. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title="castor oil">castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy" title=" epoxy"> epoxy</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=polyurethane" title=" polyurethane"> polyurethane</a> </p> <a href="https://publications.waset.org/abstracts/20839/in-situ-polymerization-and-properties-of-biobased-polyurethaneepoxy-interpenetrating-network-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20839.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">400</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">170</span> Effects of Beeswax Coating on the Properties of Cocoa Bean Shell Based Papers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Rejeki">Sri Rejeki</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamrin%20Tamrin"> Tamrin Tamrin</a>, <a href="https://publications.waset.org/abstracts/search?q=RH.%20F.%20Faradilla"> RH.

The functional properties and their lignocelluloses content make cocoa bean shells a potential material for paper-based food packaging. In our previous research, we have successfully produced papers from cocoa bean shells that had antioxidant and antibacterial activities. However, the hydrophilic nature of the lignocelluloses of cocoa bean shells hinders the application of the paper to be used as a food packaging. In this research, we aimed to study the effects of beeswax coating on the wettability and mechanical properties of the paper. The coating was done by dipping the papers in beeswax solution several times and in three different beeswax concentrations. The number of dipping and beeswax concentration significantly (p<0.05) affected the water contact angle of the papers. Results show that the water contact angle increases dramatically due to the coating treatment. The control paper or uncoated paper had a contact angle of 40.50o, while the contact angle of the best-coated paper (D3B3: 3x dipping, 3g/10mL beeswax) reached 96.93o. Both tensile strength and percent elongation were not significantly (p>0.05) affected by the coating treatment. This showed that beeswax was a potential organic material to improve the hydrophobicity of paper from cocoa bean shells without any undesirable effects on the mechanical properties of the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocoa%20bean%20shell" title="cocoa bean shell">cocoa bean shell</a>, <a href="https://publications.waset.org/abstracts/search?q=paper" title=" paper"> paper</a>, <a href="https://publications.waset.org/abstracts/search?q=beeswax" title=" beeswax"> beeswax</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20angle" title=" contact angle"> contact angle</a> </p> <a href="https://publications.waset.org/abstracts/111849/effects-of-beeswax-coating-on-the-properties-of-cocoa-bean-shell-based-papers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111849.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">148</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">169</span> Phytotoxicity of Lead on the Physiological Parameters of Two Varieties of Broad Bean (Vicia faba)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El%20H.%20Bouziani">El H.

The objective of this study was to characterize the physicochemical and antioxidant properties of black bean protein, hydrolyzed by ficin, bromelain or alcalase until 300 min of hydrolysis. Results showed that bromelain and alcalase hydrolysates possessed a higher degree of hydrolysis (DH) than that of ficin, thereby presenting different ultraviolet absorption, fluorescence intensity, and circular dichroism. Moreover, all hydrolysates possessed the capacity to scavenge DPPH radical with the lowest IC₅₀ of 21.11 µg/mL, as well as to chelate ferrous ion (Fe²⁺) with the IC₅₀ values ranging from 6.82 to 30.68 µg/mL. Intriguingly, the oxidation of linoleic acid, sunflower oil, and sunflower oil-in-water emulsion was remarkedly retarded by the three selected protein hydrolysates, especially by bromelain-treated protein hydrolysate, which might attribute to their high hydrophobicity and emulsifying properties. These findings can provide strong support for black bean protein hydrolysates to be employed in food products acting as natural antioxidant alternatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20bean%20protein%20hydrolysate" title=" black bean protein hydrolysate"> black bean protein hydrolysate</a>, <a href="https://publications.waset.org/abstracts/search?q=emulsion%20physicochemical%20properties" title=" emulsion physicochemical properties"> emulsion physicochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower%20oil" title=" sunflower oil"> sunflower oil</a> </p> <a href="https://publications.waset.org/abstracts/105885/physicochemical-and-antioxidative-characteristics-of-black-bean-protein-hydrolysates-obtained-from-different-enzymes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105885.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">137</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">167</span> Antioxidant Enzymes and Crude Mitochondria ATPases in the Radicle of Germinating Bean (Vigna unguiculata) Exposed to Different Concentrations of Crude Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stella%20O.%20Olubodun">Stella O.

The percentage germination, level of lipid peroxidation, antioxidant enzyme, and mitochondria Ca2+ and Mg2+ ATPase activities were measured in the radicle of bean after 7, 14, and 21 days post germination. Viable bean seeds were planted in soils contaminated with 10ml, 25ml, and 50ml of whole crude oil (WC) and its water soluble fraction (WSF) to obtain 2, 5, and 10% v/w crude oil contamination. There was dose dependent reduction of the number of bean seeds that germinated in the contaminated soils compared with control (p<0.001). The activities of the antioxidant enzymes, as well as, adenosine triphosphatase enzymes, were also significantly (p<0.001) altered in the radicle of the plants grown in contaminated soil compared with the control. Generally, the level of lipid peroxidation was highest after 21 days post germination when compared with control. Stress to germinating bean caused by Bonny Light crude oil or its water soluble fraction resulted in adaptive changes in crude mitochondria ATPases in the radicle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzymes" title="antioxidant enzymes">antioxidant enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=bonny%20light%20crude%20oil" title=" bonny light crude oil"> bonny light crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=radicle" title=" radicle"> radicle</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondria%20ATPases" title=" mitochondria ATPases"> mitochondria ATPases</a> </p> <a href="https://publications.waset.org/abstracts/17845/antioxidant-enzymes-and-crude-mitochondria-atpases-in-the-radicle-of-germinating-bean-vigna-unguiculata-exposed-to-different-concentrations-of-crude-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17845.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">302</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">166</span> The Influence of Addition of Asparagus Bean Powder (Psophocarpus tetragonolobus) on Gonad Maturity of Nilem Carp (Osteochilus hasselti) at the Floating Net Cage of Cirata Reservoir</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rita%20Rostika">Rita Rostika</a>, <a href="https://publications.waset.org/abstracts/search?q=Junianto"> Junianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulfiqar%20W.%20Ibrahim"> Zulfiqar W.

The research is conducted in October-July 2017 located at Cirata Reservoir and Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Jatinangor. The research employs an experimental method using a Complete Random Design (RAL) with six treatments and three repetitions. The treatments include the addition of asparagus bean powder by 0% (Control), 4% per kg of feed, 5% per kg of feed, 6% per kg of feed, 7% per kg of feed, as well as the addition of vitamin E essential as the control. The results show that the addition of asparagus bean powder to the feed may influence the gonad maturity of nilem carp shown by its Gonado Somatic Index (GSI) parameter, fecundity, egg diameter and egg reaching its maturity phase or GVBD (Germinal Vesicle Breakdown). The best administration dose influencing nilem carp is the addition of asparagus bean powder by 7% per kg of feed with the average GSI of 15.02%, relative fecundity of 137 eggs/g of fish parent weight, egg diameter of 1,263 mm, and egg reaching its maturity phase (GVBD) of 78.15%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asparagus%20bean%20powder" title="asparagus bean powder">asparagus bean powder</a>, <a href="https://publications.waset.org/abstracts/search?q=nilem%20carp" title=" nilem carp"> nilem carp</a>, <a href="https://publications.waset.org/abstracts/search?q=gonad%20maturity" title=" gonad maturity"> gonad maturity</a>, <a href="https://publications.waset.org/abstracts/search?q=Cirata%20reservoir" title=" Cirata reservoir"> Cirata reservoir</a> </p> <a href="https://publications.waset.org/abstracts/85513/the-influence-of-addition-of-asparagus-bean-powder-psophocarpus-tetragonolobus-on-gonad-maturity-of-nilem-carp-osteochilus-hasselti-at-the-floating-net-cage-of-cirata-reservoir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85513.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">167</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">165</span> Evaluation of Botanical Plant Powders against Zabrotes subfasciatus (Boheman) (Coleoptera: Bruchidae) in Stored Local Common Bean Varieties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fikadu%20Kifle%20Hailegeorgis">Fikadu Kifle Hailegeorgis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Common bean is one of the most important sources of protein in Ethiopia and other developing countries. However, the Mexican bean weevil, Zabrotes subfasciatus (Boheman), is a major factor in the storage of common beans that causes losses. Studies were conducted to evaluate the efficacy of botanical powders of Jatropha curcas (L.), Neem/Azadrachta indica, and Parthenium hysterophorus (L) on local common bean varieties against Z subfasciatus at Melkassa Agriculture Research Center. Twenty local common bean varieties were evaluated twice against Z. Subfasciatus in a completely randomized design in three replications at the rate of 0.2g/250g of seed for each experiment. Malathion and untreated were used as standard checks. The result indicated that RAZ White and Round Yellow showed high resistance variety in experiments while Batu and Black showed high susceptible variety in experiments. Jatropha seed powder was the most effective against Z. subfasciatus. Parthenium seed powders and neem leaf powders also indicate promising results. Common beans treated with botanicals significantly (p<0.05) had a higher germination percentage than that of the untreated seed. In general, the results obtained indicated that using bean varieties (RAZ white and Round yellow) and botanicals (Jatropha) seed powder gave the best control of Z. subfasciatus. <p
