Öğe Consumption of underutilised grain legumes and the prevention of type II diabetes and cardiometabolic diseases: Evidence from field investigation and physicochemical analyses(Elsevier B.V., 2022) Hamadou M.; Martin Alain M.M.; Obadias F.V.; Hashmi M.Z.; Başaran B.; Jean Paul B.; Samuel René M.This study was carried out to correlate grain legume consumption to the prevention of type II diabetes and some cardiometabolic diseases (CMD) (high blood pressure, obesity, and stroke). An exploratory survey was carried out among the population (n = 468) of the Diamaré division (Far-north, Cameroon). In addition, nutritional properties of selected grain legumes (GLs) were determined. Results showed generally that consumption of soybean, Bambara bean, and cowpea was linked to the prevention of metabolic diseases within the studied population. The nutritional properties of these GLs were also noteworthy. Remarkable protein content was noted in soybean's whole flour (WF) (38.133±0.366 g/100g DM), followed by the underutilised cultivar BVB of Bambara bean (26.434±0.366 g/100g DM). The cowpea seed has the highest total carbohydrate and vitamin C content of 59.294±0.129 g/100g DM and 327.715±0.336 µg EAA/100g DM, respectively, followed by the underutilised cultivar BVB with values of 57.696±0.097 g/100g DM and 261.951±0.376 µg EAA/100g DM. Dietary fibre content of Bambara bean seeds (18 - 28%) was higher than those of the other seeds, and probably plays important role in the prevention ability of diabetes and CMD of Bambara bean. Soybean's WF and those of the three underutilised Bambara bean cultivars contained the highest levels of total phenolic compounds and flavonoids, i.e., 206.089±0.087 mg GAE/100 DM, 143.868±0.299 mg QE/100g DM for soybean, respectively. The highest free radical scavenging activity (DPPH) was noted with the polyphenolic compounds’ extracts from soybean's WF, i.e., 21.193±0.049 µg TE/100g DM, followed by those from the underutilised BVB cultivar with a value of 16.594±0.160 µg TE/100g DM. The highest ferric reducing antioxidant power (FRAP) was obtained with soybean (34.481±0.029 µg TE/100g DM), followed by the cultivar GHB (32.036±0.076 µg TE/100g DM). The significant levels of protein, phenolic compounds, and dietary fibre in these seeds confirmed these correlations and their potential therapeutic effects and nutritional properties. Given the richness of the grain legumes in proteins and other bioactive compounds, raw materials and/or protein hydrolysates (peptides) will surely be a promising raw material for the pharmaceutical industries in the fight and/or prevention of metabolic diseases, in the fight against food insecurity, in the prevention and/or reversal of neurodegenerative diseases, and the formulation of a new functional ingredient. © 2022Öğe Effect of different atmospheric conditions on some physical properties of leather(2011) Başaran B.; Bitlisli B.O.; Ocak B.; Önem E.In this study, the effect of conditioning under standard and tropical atmospheric conditions on physical properties of leather was investigated. For this purpose, garment sheep leathers were conditioned under standard atmospheric conditions of 23 °C ± 2 °C temperature and % 50 ± relative humidity suggested in TS EN ISO 2419, and under tropical atmospheric conditions of 27 °C ± 2 °C temperature and % 65 ± 5 relative humidity suggested in ISO/DIS 2419. Then, changes in leather physical properties were investigated statistically. According to results, for sheep leather conditioned under standard atmospheric conditions, percentage extension was 53.47 ± 4.10, Young's modulus was 77.32 ± 23.34 N/mm, double edge tear load was 38.03 ± 8.47 N, water vapour permeability was 6.18 ± 0.55 mg/cm2.h, while under tropical atmospheric conditions, percentage extension was 57.67 ± 5.36, Young's modulus was 69.42 ± 13.87 N/mm, double edge tear load was 43.06 ± 10.50 N, water vapour permeability was 6.61 ± 0.47 mg/cm2.h. The difference between these physical properties was determined to be statistically significant. Changes in tensile strength and single edge tear load were not significant.Öğe Heavy metal contents of bootee leathers tanned with different process recipes(2011) Karavana H.A.; Başaran B.; Aslan A.; Bitlisli B.O.; Gülümser G.The purpose of this work was to determine the content of heavy metals such as antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium in leather used by producing baby bootees and to compare the limit values for leather and textiles. It was concluded that heavy metal content of finished leathers depended mainly on the chemicals used in processing; in particular, high chromium contents were determined. Moreover, small amounts of antimony, arsenic, barium, cadmium, lead, mercury and selenium deriving from chemical and physical reactions during dyeing and finishing processes were detected.Öğe A novel lubricant with Nano-silica additives and its uses for leather performance properties(International Union of Leather Technologists and Chemists Societies (IULTCS), 2015) Erciyes A.; Yigit R.; Başaran B.; Ocak B.; Çelik E.Leather has a fibrous network gives many favourable properties in line with consumer demands. Thanks to lubrication, both the individual fibers of the network become compliance, thereby, maintaining its mechanical behaviour and the structure would be improved regarding the homogeneity, unity, uniformity and appearance. Hence, the key function of lubricant is to enhance the physico-mechanical properties of leathers and to upgrade their qualities by adding aesthetic value. Those are achieved by use of lubricant emulsions of small particle size capable of deeply penetrating into the hierarchy of tridimensional woven structure. Nano-silica particles are of potential advantages for incorporation into fatliquoring formulations because of their lubricating efficiencies and there will take many interests in terms of attainable value added products with them.Öğe Properties of leathers tanned with ti-al based tanning materials obtained from the wastes of metal industry(2012) Mutlu M.M.; Zengin A.C.A.; Crudu M.; Maier S.S.; Deselnicu V.; Albu L.; Gulumser G.; Bitlisli B.O.; Başaran B.; Tosun C.C.Although chromium tanning is the most popular tanning system worldwide, it is held under the microscope due to increasing requirements on disposal of chromium tanning effluents, by-products and sludge. For this reason; in last decades, researches on alternative tanning materials which will decrease or replace chromium usage take a great share among the main topics in the area of leather researches. In this research, a newly produced titanium based tanning agent, obtained from processing wastes from the industry of nonferrous metals was used as an alternative to chromium tanning agent. The new titanium tanning agent was experimented with 1%, 2.5%, 5%, 7.5 and 10% dosages. Physical tests and chemical analysis of the produced chromium-free leathers gave comparable results to leathers tanned with basic chromium sulphate. 5% usage of titanium tanning agent was found to be optimal.Öğe Some physical and chemical properties of ostrich skins and leathers(2004) Bitlisli B.O.; Başaran B.; Sari Ö.; Aslan A.; Zengin G.Some technological parameters of ostrich skins and leathers, which are considered to be important in the leather industry, were analysed. It was observed that these parameters vary according to whether skin comes from the neck, leg and back sides. However, on the basis of area and strength values, leg and back sides are more appropriate for upper leather production and neck sides may be used as accessories.Öğe Structural and physicomechanical characteristics of leatherheads used in various percussion instruments(2013) Alaskan A.M.; Başaran B.; Nalbat S.Musical sound in percussion instruments is an energy being emited through the vibrational waves from the structural components of leatherheads which becomes unstable due to mechanical agitation. This vibration is strictly bound up with the structural and therefore physicomechanical characteristics naturally available. The study was carried out on 12 leatherheads processed for percussion instrument, the structural evaluation was practiced by optoanalytical techniques and physicomechanical characteristics such as tensile strength, elongation (%), elasticity modulus, hardness (Shore A and D) and apparent density were examined in order to find out the resistance and behaviors against the mechanical effects like stretching, tuning and playing. According to the results; the leatherheads used for percussion instruments making were found to be much more tightly and compact structured, and also have high apparent density as compared to the leathers processed for garments, shoe uppers and leather goods. As consequences of compactly packed structure, for the same comparison, the leatherheads were found to have different mechanical behavior, being more resistant and having harder handle but indicating lower elongation (%).Öğe A study of the realistic strength of leather: True stress(2012) Başaran B.; Nalbat S.Strength deals with the durability of materials during usage and therefore is an important criterion for performance evaluation. Leather goods, which continue to be preferred by many over artificial substitutes, need to exhibit durable material performance. Strength testing, as related to an understanding of the endurance against force, is an important component of overall material behavior. Therefore, tensile testing should be well developed so as to analyze the properties of finished leathers and acquire realistic practical data. This study deals, in detail, with the evaluation of tensile properties considering the differences between engineering stress and true stress. In this examination of tensile behaviors three groups of garment leathers with different finishes (aniline, semi-aniline, and full pigmented finishes) were used. The samples were evaluated comparing engineering stress and true stress. In a Completely Randomized Design study, the statistical differences were calculated by the Duncan test in the level of P?0.05. Thereby, statistically significant differences between engineering stress and true stress between each of the three groups was verified.
