Optimized Extraction of Dietary Fiber from Defatted Rice Bran and Evaluation of the Fiber-fortified Drink Yogurt

Cellulase-assisted extraction of oligosaccharides from defatted rice bran.

Defatted rice bran was subjected to cellulase treatment in order to increase its extractable oligosaccharides. Various combinations of enzyme concentration (0%, 0.5%, 1.0%, and 2.0%), temperature (room, 30, 40, and 50 degrees C), and time (1, 3, 5, and 16 h) were tested to identify the optimum extraction conditions. The saccharide content and composition of the extracts were analyzed by high-pe...

optimization of alkaline fiber extraction from rice bran using response surface methodology

introduction: the consumption of dietary fiber plays an important role in the prevention of illnesses such as diabetes type 2, hypercholesterolemia. dietary fibers are not only desirable for their nutritional properties but also for their functional and technological properties. this study was undertaken to investigate the possibility of alkaline hydrolysis to remove fiber from rice bran. mater...

Development of a Frozen Yogurt Fortified with a Nano-emulsion Containing Purple Rice Bran Oil

Study on Functional Properties of Physically Modified Dietary Fibres Derived from Defatted Rice Bran

In this study, we investigated the predictive indices for hypoglycemic effect of physically modified fibers. Micronization, ultrasonic, microwave and extrusion cooking treatments were applied to defatted rice bran dietary fibers to get modified defatted rice bran dietary fiber. The effects of physical treatments, pH and time of digestion, on the water binding Capacity (WBC), Swelling Capacity (...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
