However, challenges such as sensory drawbacks and the presence of phenolic compounds have hindered their widespread use. In this study, sunflower protein concentrates were obtained from sunflower cakes using different ant-greening solvents (ascorbic acid (ASC) and N-acetylcysteine (NAC)), and their functional properties were evaluated. The color of extracted proteins ranged from dark green to yellow, where the using of ASC and NAC agents enhanced the color. The protein concentrates exhibited high solubility (>70%) and antioxidant activity, with hydrophobicity influencing emulsifying activity. Emulsions prepared with these proteins showed stability and microencapsulation efficiency. Incorporation of protein concentrates into low-fat whipping cream formulations increased overrun and affected color characteristics. Rheological studies demonstrated pseudoplastic behavior in whipped cream, influenced by shear rates and protein content. Overall, sunflower protein isolates showed promising functional properties, indicating their potential as valuable ingredients in food formulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title="functional properties">functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower%20protein%20concentrates" title=" sunflower protein concentrates"> sunflower protein concentrates</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20capacity" title=" antioxidant capacity"> antioxidant capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=ant-greening%20agents" title=" ant-greening agents"> ant-greening agents</a>, <a href="https://publications.waset.org/abstracts/search?q=low-fat%20whipping%20cream" title=" low-fat whipping cream"> low-fat whipping cream</a> </p> <a href="https://publications.waset.org/abstracts/185953/functional-properties-of-sunflower-protein-concentrates-extracted-using-different-anti-greening-agents-low-fat-whipping-cream-preparation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185953.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">56</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">11336</span> Ab Initio Studies of Structural and Thermal Properties of Aluminum Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Saadi">M.

The calculations were performed for within several exchange–correlation functional and pseudo pententials available in this code (local density approximation (LDA), generalized gradient approximation (GGA), projector augmented wave (PAW)). The lattice dynamic code “PHON” developed by Dario Alfè was used to calculate some thermodynamics properties and phonon dispersion relation frequency distribution of Aluminium alloys using the VASP LDA PAW and GGA PAW results.

With a dramatically increasing consumption of chicken product in the world, there are abundant wastes from chicken meat processing industry. Recently, much research in the development of value-added products from chicken meat industry has focused on the production of protein hydrolysate, utilized as food ingredients for human diet and animal feed. The present study aimed to determine the effect of thermal pre-treatment on functional properties of chicken protein hydrolysate. Chicken breasts were heated at 40, 60, 80 and 100ºC prior to hydrolysis by Alcalase at 60ºC, pH 8 for 4 hr. The hydrolysate was freeze-dried, and subsequently used for assessment of its functional properties molecular weight by gel electrophoresis (SDS-PAGE). The obtained results show that increasing the pre-treatment temperature increased oil holding capacity and emulsion stability while decreasing antioxidant activity and water holding capacity. The SDS-PAGE analysis showed the evidence of protein aggregation in the hydrolysate treated at the higher pre-treatment temperature. These results suggest the connection between molecular weight of the hydrolysate and its functional properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicken%20protein%20hydrolysate" title="chicken protein hydrolysate">chicken protein hydrolysate</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymatic%20hydrolysis" title=" enzymatic hydrolysis"> enzymatic hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20pretreatment" title=" thermal pretreatment"> thermal pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title=" functional properties"> functional properties</a> </p> <a href="https://publications.waset.org/abstracts/56093/effect-of-thermal-pretreatment-on-functional-properties-of-chicken-protein-hydrolysate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56093.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">276</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">11334</span> Bound State Problems and Functional Differential Geometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Srednyak">S.

We derive general properties of solutions to such equations. In particular, we demonstrate that they lead to systems of coupled integral equations with singular kernels. We show that solutions to such hierarchies can be sought among functions with regular singularities at a countable set of subvarieties of the physical space. We also develop a formal analogy of basic constructions of differential geometry on functional manifolds, as this is necessary for in depth study of FPDEs. We also consider the case of linear overdetermined systems of functional differential equations and show that it can be completely solved in terms of formal solutions of a functional equation that is a functional analogy of a system of determined algebraic equations. This development leads us to formally define the functional analogy of algebraic geometry, which we call functional algebraic geometry. We study basic properties of functional algebraic varieties. In particular, we investigate the case of a formally discrete set of solutions. We also define and study functional analogy of discriminants. In the case of fully determined systems such that the defining functionals have regular singularities, we demonstrate that formal solutions can be sought in the class of functions with regular singularities. This case provides a practical way to apply our results to physics problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20equations" title="functional equations">functional equations</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20field%20theory" title=" quantum field theory"> quantum field theory</a>, <a href="https://publications.waset.org/abstracts/search?q=holomorphic%20functions" title=" holomorphic functions"> holomorphic functions</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Mills%20mass%20gap%20problem" title=" Yang Mills mass gap problem"> Yang Mills mass gap problem</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20chaos" title=" quantum chaos"> quantum chaos</a> </p> <a href="https://publications.waset.org/abstracts/173716/bound-state-problems-and-functional-differential-geometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173716.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">78</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">11333</span> The Effect of Hydrogen on the Magnetic Properties of ZnO: A Density Functional Tight Binding Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Lahmer">M.

Starch is a certainly happening, ecological, reasonable and profusely obtainable polysaccharide in plant material. In the present scenario, there is a great interest in modifying starch functional properties without destroying its granular structure using different modification techniques. Resistant starch (RS) contains almost zero calories and can control blood glucose level to prevent diabetes. The current study focused on modification of mung bean starch which is a good source of legumes carbohydrate for the production of functional food. Heat moisture treatment (HMT) of mung starch was conducted at moisture content of 10-30%, temperature of 80-120 °C and time of 8-24 h.The content of resistant starch after modification was significantly increased from native starches containing RS 7.6%. The design combinations of HMT had been completed through Central Composite Rotatable Design (CCRD). The effects of HMT process variables on the yield of resistant starch was studied through Rapid Surface Methodology (RSM). The highest increase of resistant starch was found up to 34.39% when treated the native starch with 30% m.c at 120 °C temperature for 24 h.The functional properties of both native and modified mung bean starches showed that there was a reduction in the swelling power and swelling volume of HMT starches. However, the solubility of the HMT starches was higher than that of untreated native starch and also observed change in structural (scanning electron microscopy), X-Ray diffraction (XRD) pattern, blue value and thermal (differential scanning calorimetry) properties. Therefore, replacing native mung bean starch with heat-moisture treated mung bean starch leads to the development of new products with higher resistant starch levels and functional properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mung%20bean%20starch" title="Mung bean starch">Mung bean starch</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20moisture%20treatment" title=" heat moisture treatment"> heat moisture treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title=" functional properties"> functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=resistant%20starch" title=" resistant starch"> resistant starch</a> </p> <a href="https://publications.waset.org/abstracts/70938/impact-of-heat-moisture-treatment-on-the-yield-of-resistant-starch-and-evaluation-of-functional-properties-of-modified-mung-bean-vigna-radiate-starch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70938.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">208</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">11331</span> Density functional (DFT), Study of the Structural and Phase Transition of ThC and ThN: LDA vs GGA Computational</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Rekab%20Djabri">Hamza Rekab Djabri</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Daoud"> Salah Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper deals with the computational of structural and electronic properties of ThC and ThN compounds using density functional theory within generalized-gradient (GGA) apraximation and local density approximation (LDA).

Such a process could induce the modification of the functional properties of the chips, thus reducing the technological uses of these products. This study was conducted with a view to assessing the impact of this process on the chips of D. schimperiana. Methods: The chips used were purchased in Baham, Bamendjou and Bagangté markets during the month of February 2013. A representative sample of each market chips was formed by mixing the chips of several sellers. The control sample consisted of fresh yams that have been sliced to the average size of local chips then dried in the oven at 45 ° C for 36 h. On each sample was performed the analysis of the physico-chemical properties (carbohydrates, lipids, proteins, iron , phosphorus, reducing sugars, ash and total starch) and gelling properties both with and without inhibitor alpha-amylases (0.018 and 0.146 mol / l). Results: Results show that the levels of ash 2.99 g / 100gms, iron 1.01 g / 100gms and phosphorus 532.06 mg / 100gms fresh sample were significantly higher than those of the products obtained in the traditional process. The functional properties of the chips obtained from different methods shows that the peak viscosity of the fresh sample is larger than the other samples with or without inhibitor. In addition, the fresh sample has the lowest breakdown under the same conditions. Conclusion: These results show that traditional process reduces technological potential of chips, thus limiting the value of D. schimperiana. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dioscorea%20schimperiana" title="Dioscorea schimperiana">Dioscorea schimperiana</a>, <a href="https://publications.waset.org/abstracts/search?q=chips" title=" chips"> chips</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title=" functional properties"> functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20properties" title=" technological properties"> technological properties</a>, <a href="https://publications.waset.org/abstracts/search?q=valorization" title=" valorization "> valorization </a> </p> <a href="https://publications.waset.org/abstracts/25093/influence-of-cooking-on-the-functional-properties-of-dioscorea-schimperiana-during-chips-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25093.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">405</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">11329</span> Density Functional Theory (DFT) Study of Structural, Electronic and Thermodynamic Properties of the Low-Temperature LT-Mg₂NiH₄ Hydride</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Mosteghanemi">N.

Compared with multivariate linear regression, functional linear regression is regarded as an infinite-dimensional case, and the main task is to reduce dimensions of functional response and functional predictors. One common approach is to adapt functional principal component analysis (FPCA) on functional predictors and then use a few leading functional principal components (FPC) to predict the functional model. The leading FPCs estimated by the typical FPCA explain a major variation of the functional predictor, but these leading FPCs may not be mostly correlated with the functional response, so they may not be significant in the prediction for response. In this paper, we propose a supervised functional principal component analysis method for a functional response model with FPCs obtained by considering the correlation of the functional response. Our method would have a better prediction accuracy than the typical FPCA method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supervised" title="supervised">supervised</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20principal%20component%20analysis" title=" functional principal component analysis"> functional principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20response" title=" functional response"> functional response</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20linear%20regression" title=" functional linear regression"> functional linear regression</a> </p> <a href="https://publications.waset.org/abstracts/177071/estimation-of-functional-response-model-by-supervised-functional-principal-component-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177071.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">83</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">11327</span> Opto-Electronic Properties of Novel Structures: Sila-Fulleranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farah%20Marsusi">Farah Marsusi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Qasemnazhand"> Mohammad Qasemnazhand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Density-functional theory (DFT) was applied to investigate the geometry and electronic properties H-terminated Si-fullerene (Si-fullerane).

Fermentation, an effective processing method used to improve nutritional quality of plant foods, tends to affect the characteristics of food components and their behaviour in food systems just like other processing methods. Hence the need for this study. Moringa seeds were fermented naturally by soaking in potable water and allowing it to stand for 12, 24, 48 and 72 hours. At the end of fermentation, the seeds were oven dried at 600C for 12 hours and then milled into flour. Flour obtained from unfermented seeds served as control: hence a total of five flour samples. The functional properties were analyzed using standard methods. Fermentation significantly (p<0.05) increased the water holding capacity of Moringa seed flour from 0.86g/g - 2.31g/g. The highest value was observed after 48 hours of fermentation The same trend was observed for oil absorption capacity with values between 0.87 and 1.91g/g. Flour from unfermented Moringa seeds had a bulk density of 0.60g/cm3 which was significantly (p<0.05) higher than the bulk densities of flours from seeds fermented for 12, 24 and 48. Fermentation significantly (p<0.05) decreased the dispersibility of Moringa seed flours from 36% to 21, 24, 29 and 20% after 12, 24, 48 and 72 hours of fermentation respectively. The flours’ emulsifying capacities increased significantly (p<0.05) with increasing fermentation time with values between 50 – 68%. The flour obtained from seeds fermented for 12 hours had a significantly (p<0.05) higher foaming capacity of 16% while the flour obtained from seeds fermented for 0, 24 and 72 hours had the least foaming capacities of 9%. Flours from seeds fermented for 12 and 48 hours had better functional properties than flours from seeds fermented for 24 and 72 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fermentation" title="fermentation">fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=flour" title=" flour"> flour</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title=" functional properties"> functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Moringa" title=" Moringa"> Moringa</a> </p> <a href="https://publications.waset.org/abstracts/20328/effect-of-fermentation-time-on-some-functional-properties-of-moringa-moringa-oleifera-seed-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20328.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">700</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">11325</span> Preparation and Functional Properties of Synbiotic Yogurt Fermented with Lactobacillus brevis PML1 Derived from a Fermented Cereal-Dairy Product</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farideh%20Tabatabei-Yazdi">Farideh Tabatabei-Yazdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fereshteh%20Falah"> Fereshteh Falah</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Vasiee"> Alireza Vasiee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, production of functional foods has become very essential.

Furthermore, the physicochemical properties, antioxidant activity, sensory attributes, and microbial viability properties were investigated on the 0th, 7th, and 14th days of storage after fermentation. The viable cells of L. brevis PML1 reached 108 CFU/g, and the product resisted to simulated digestive juices. Moreover, the synbiotic yogurt impressively increased the production of antimicrobial compounds and had the most profound antimicrobial effect on S. typhimurium. The physiochemical properties were in the normal range, and the fat content of the synbiotic yogurt was reduced remarkably. The antioxidant capacity of the fermented yogurt was significantly increased (p<0:05), which was equal to those of DPPH (69:18±1:00%) and BHA (89:16±2:00%). The viability of L. brevis PML1 was increased during storage. Sensory analysis showed that there were significant differences in terms of the impressive parameters between the samples and the control (p<0:05). Addition of 2.5% inulin not only improved the physical properties but also retained the viability of the probiotic after 14 days of storage, in addition to the viability of L. brevis with a viability count above 6 log CFU/g in the yogurt. Therefore, a novel synbiotic product containing L. brevis PML1, which can exert the desired properties, can be used as a suitable carrier for the delivery of the probiotic strain, exerting its beneficial health effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title="functional food">functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=lactobacillus%20brevis" title=" lactobacillus brevis"> lactobacillus brevis</a>, <a href="https://publications.waset.org/abstracts/search?q=symbiotic%20yogurt" title=" symbiotic yogurt"> symbiotic yogurt</a>, <a href="https://publications.waset.org/abstracts/search?q=physiochemical%20properties" title=" physiochemical properties"> physiochemical properties</a> </p> <a href="https://publications.waset.org/abstracts/150723/preparation-and-functional-properties-of-synbiotic-yogurt-fermented-with-lactobacillus-brevis-pml1-derived-from-a-fermented-cereal-dairy-product" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150723.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">95</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">11324</span> The Influence of Winding Angle on Functional Failure of FRP Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roham%20Rafiee">Roham Rafiee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Hesamsadat"> Hadi Hesamsadat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a parametric finite element modeling is developed to analyze failure modes of FRP pipes subjected to internal pressure.

To treat the strong correlation effects caused by 5f Uranium valence electrons, on-site Coulomb interaction correction via the Hubbard-like term, U (DFT+U) was employed. The UN2 structural, mechanical and thermodynamic properties were calculated within DFT and Various U of DFT+U approach. The Perdew–Burke–Ernzerhof (PBE.5.2) version of the generalized gradient approximation (GGA) is used to describe the exchange-correlation with the projector-augmented wave (PAW) pseudo potentials. A comparative study shows that results are improved by using the Hubbard formalism for a certain U value correction like the structural parameter. For some physical properties the variation versus Hubbard U is strong like Young modulus but for others it is weakly noticeable such as the density of state (DOS) or bulk modulus. We noticed also that up from U=7.5 eV, elastic results become not conform to the cubic cell elastic criteria since the C44 values turn out to be negative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=uranium%20diNitride" title="uranium diNitride">uranium diNitride</a>, <a href="https://publications.waset.org/abstracts/search?q=UN2" title=" UN2"> UN2</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT%2BU" title=" DFT+U"> DFT+U</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20properties" title=" elastic properties"> elastic properties</a> </p> <a href="https://publications.waset.org/abstracts/14079/physical-properties-of-uranium-dinitride-un2-by-using-density-functional-theory-dft-and-dftu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14079.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">458</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">11321</span> High-Pressure Calculations of the Elastic Properties of ZnSx Se 1−x Alloy in the Virtual-Crystal Approximation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Lebga">N.

African walnut seeds were sorted washed, soaked, cooked, dehulled, sliced, dried and milled. Proximate analysis and functional properties of the samples were evaluated using standard procedures. Data obtained were analyzed using descriptive and inferential statistics. Quadratic models were obtained to predict the proximate and functional qualities as a function of cooking time, seed-to-water ratio and soaking time. The results showed that the crude protein ranged between 11.80% and 23.50%, moisture content ranged between 1.00% and 4.66%, ash content ranged between 3.35% and 5.25%, crude fibre ranged from 0.10% to 7.25% and carbohydrate ranged from 1.22% to 29.35%. The functional properties showed that soluble protein ranged from 16.26% to 42.96%, viscosity ranged from 23.43 mPas to 57 mPas, emulsifying capacity ranged from 17.14% to 39.43% and water absorption capacity ranged from 232% to 297%. An increase in the volume of water used during cooking resulted in loss of water soluble protein through leaching, the length of soaking time and the moisture content of the dried product are inversely related, ash content is inversely related to the cooking time and amount of water used, extraction of fat is enhanced by increase in soaking time while increase in cooking and soaking times result into decrease in fibre content. The results obtained indicated that African walnut could be used in several food formulations as protein supplement and binder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20walnut" title="African walnut">African walnut</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title=" functional properties"> functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=proximate%20analysis" title=" proximate analysis"> proximate analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a> </p> <a href="https://publications.waset.org/abstracts/11005/effect-of-cooking-time-seed-to-water-ratio-and-soaking-time-on-the-proximate-composition-and-functional-properties-of-tetracarpidium-conophorum-nigerian-walnut-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11005.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">401</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">11319</span> Atomic Hydrogen Storage in Hexagonal GdNi5 and GdNi4Cu Rare Earth Compounds: A Comparative Density Functional Theory Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Kellou">A.

Bioisosteres have similar pharmacological properties. Bioisosterism is useful for modifying the physicochemical properties of a drug while obeying the Lipinski’s rules. Bioisosteres are key in optimizing the pharmacokinetic and pharmacodynamics properties of a drug. Tetrazole and carboxylate anions are non-classic bioisosteres. Density functional theory was used to obtain the wavefunction of the molecules and the optimized geometries. The quantum theory of atoms in molecules (QTAIM) was used to uncover the similarity of the average electron density in tetrazole and carboxylate anions. This similarity between the bioisosteres capped by a methyl group was valid despite the fact that the groups have different volumes, charges, energies, or electron populations. The biochemical correspondence of tetrazole and carboxylic acid was also determined to be a result of the similarity of the topography of the electrostatic potential (ESP). The ESP demonstrates the pharmacological and biochemical resemblance for a matching “key-and-lock” interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioisosteres" title="bioisosteres">bioisosteres</a>, <a href="https://publications.waset.org/abstracts/search?q=carboxylic%20acid" title=" carboxylic acid"> carboxylic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title=" density functional theory"> density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20potential" title=" electrostatic potential"> electrostatic potential</a>, <a href="https://publications.waset.org/abstracts/search?q=tetrazole" title=" tetrazole"> tetrazole</a> </p> <a href="https://publications.waset.org/abstracts/22652/similarity-of-the-disposition-of-the-electrostatic-potential-of-tetrazole-and-carboxylic-group-to-investigate-their-bioisosteric-relationship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22652.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">445</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">11316</span> Role of Interlayer Coupling for the Power Factor of CuSbS2 and CuSbSe2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Najebah%20Alsaleh">Najebah Alsaleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nirpendra%20Singh"> Nirpendra Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Udo%20Schwingenschlogl"> Udo Schwingenschlogl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electronic and transport properties of bulk and monolayer CuSbS2 and CuSbSe2 are determined by using density functional theory and semiclassical Boltzmann transport theory, in order to investigate the role of interlayer coupling for the thermoelectric properties.

As results, these compounds are competent candidates for optoelectronic and photovoltaic devices in this range of the energy spectrum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory%20%28DFT%29" title="density functional theory (DFT)">density functional theory (DFT)</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor%20behavior" title=" semiconductor behavior"> semiconductor behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=metalloid%20halide%20perovskites" title=" metalloid halide perovskites"> metalloid halide perovskites</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20propertie%20and%20photovoltaic%20devices" title=" optical propertie and photovoltaic devices"> optical propertie and photovoltaic devices</a> </p> <a href="https://publications.waset.org/abstracts/174943/physical-properties-of-new-perovskite-kgex3-x-f-cl-and-br-for-photovoltaic-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174943.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">11314</span> Physicochemical and Microbiological Properties of Kefir, Kefir Yogurt and Chickpea Yogurt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuray%20G%C3%BCzeler">Nuray Güzeler</a>, <a href="https://publications.waset.org/abstracts/search?q=Elif%20Ari"> Elif Ari</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6zde%20Konuray"> Gözde Konuray</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%87a%C4%9Fla%20%C3%96zbek"> Çağla Özbek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The consumption of functional foods is very common. For this reason, many products which are probiotic, prebiotic, energy reduced and fat reduced are developed. In this research, physicochemical and microbiological properties of functional kefir, kefir yogurt and chickpea yogurt were examined. For this purpose, pH values, titration acidities, viscosity values, water holding capacities, serum separation values, acetaldehyde contents, tyrosine contents, the count of aerobic mesophilic bacteria, lactic acid bacteria count and mold-yeast counts were determined. As a result of performed analysis, the differences between titration acidities, serum separation values, water holding capacities, acetaldehyde and tyrosine contents of samples were statistically significant (p < 0.05). There were no significant differences on pH values, viscosities, and microbiological properties of samples (p > 0.05). Consequently industrial production of functional kefir yogurt and chickpea yogurt may be advised. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chickpea%20yogurt" title="chickpea yogurt">chickpea yogurt</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir" title=" kefir"> kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir%20yogurt" title=" kefir yogurt"> kefir yogurt</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a> </p> <a href="https://publications.waset.org/abstracts/71188/physicochemical-and-microbiological-properties-of-kefir-kefir-yogurt-and-chickpea-yogurt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71188.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">11313</span> Biochemical and Electrochemical Characterization of Glycated Albumin: Clinical Relevance in Diabetes Associated Complications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20Raghav">Alok Raghav</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Ahmad"> Jamal Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Serum albumin glycation and advanced glycation end products (AGE) formation correlates in diabetes and its associated complications. Extensive modified human serum albumin is used to study the biochemical, electrochemical and functional properties in hyperglycemic environment with relevance to diabetes. We evaluate Spectroscopic, side chain modifications, amino acid analysis, biochemical and functional group properties in four glucose modified samples. Methods: A series four human serum albumin samples modified with glucose was characterized in terms of amino acid analysis, spectroscopic properties and side chain modifications. The diagnostic technique employed incorporates UV Spectroscopy, Fluorescence Spectroscopy, biochemical assays for side chain modifications, amino acid estimations. Conclusion: Glucose modified human serum albumin confers AGE formation causes biochemical and functional property that depend on the reactivity of glucose and its concentration used for in-vitro glycation. A biochemical and functional characterization of modified albumin in-vitro produced AGE product that will be useful to interpret the complications and pathophysiological significance in diabetes. <p
