Optimization of Arabinoxylan Isolation from Rye Bran by Adapting Extraction Solvent and Use of Enzymes
Physicochemical and functional properties of arabinoxylans (AXs) can be significantly influenced by their isolation method. Finding balanced process conditions that allow optimal extraction yields while preserving AXs functionality is a challenge. The aim of this study was to determine the effect of different chemical solvents with neutral and alkaline pH on the intrinsic properties and extract...

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 ...
15 صفحه اولEffects of processed rye bran and raw rye bran on glucose metabolism in alloxan diabetic rats.
Alloxan diabetic rats (D) and control rats (C) were for 14 days fed a basic diet made from a mixture of rye bread and milk containing either no bran (group O), processed bran (group PB) or raw bran (group B). The D-B animals has a lower urinary glucose excretion (36 +/- 4 mmoles/24 hours) than the D-PB animals (63 +/- 5 mmoles/24 hours), which in their turn had a lower excretion than the D-0 an...
متن کاملEntrapment of probiotics in water extractable arabinoxylan gels: rheological and microstructural characterization.
Due to their porous structure, aqueous environment and dietary fiber nature arabinoxylan (AX) gels could have potential applications for colon-specific therapeutic molecule delivery. In addition, prebiotic and health related effects of AX have been previously demonstrated. It has been also reported that cross-linked AX can be degraded by bacteria from the intestinal microbiota. However, AX gels...
متن کاملLycopene/arabinoxylan gels: rheological and controlled release characteristics.
Arabinoxylan gels exhibiting different rheological and lycopene transport properties were obtained by modifying the polysaccharide concentration from 3 to 4% (w/v). The apparent lycopene diffusion coefficient decreased from 2.7 × 10⁻⁷ to 2.4 × 10⁻⁷ cm²/s as the arabinoxylan concentration in the gel changed from 3 to 4% (w/v). A low amount of lycopene is released by diffusion from arabinoxylan g...
