Physical and mechanical properties of peanut kernels are important to the researcher, design engineer, the food industry. The present study aimed to determine and recognize a database of physical and engineering properties of peanut seed which play an important role in designing and developing of specific machines and their operations such as planting, harvesting and grading. The physical properties namely Moisture content, % (w.b), Length (mm), Width (mm), Thickness (mm), Shape, Sphericity (mm), 100 kernels weight (mm), Geometric mean diameter (mm), Surface area (mm2), Aspect ratio (%), True density (kg/m3), Bulk density (kg/m3), Porosity (%), Angle of repose, degree, Terminal velocity (m/s), Coefficient of friction (Wood, Glass and GI surface) and Germination percentage (%) of peanuts variety
kernel GG-20 and TG-37A were investigate and reported in this study. Size distribution of GG-20 and TG-37A peanut kernels also studied.
Fat Wars by Combination of Green Tea Extract and Caffeine, Burning more Calories and Effect on Fat Oxidation in Humans
Green tea catechins (GTC) are polyphenolic compounds present in the unfermented dried leaves of the plant. The result from a number of studies observed consumption of GTC (270 mg to 1200 mg/day) may reduce body weight and fat. Caffeine, naturally present in green tea, also influences sympathetic nervous system (SNS) activity, and may act synergistically with GTC to increase energy expenditure and fat oxidation. The role of green tea extract (GTE) is fat metabolism and its influence on health and exercise performance. The results illustrated from a number of papers positive effects of GTE on fat metabolism at rest and during exercise, following both shorter and longer term intake. Catechin-caffeine
mixtures or a caffeine-only supplementation stimulates daily energy expenditure dose dependently by 0.4–0.5 kJ mg-1 administered. Compared with placebo, daily fat-oxidation was only significantly increased after catechin-caffeine mixtures ingestion.[2,6,7,9]
