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 ...
15 صفحه اولExtraction and characterization of gelling pectin from the peel of Poncirus trifoliata fruit
In the framework of searching for new pectin sources to partially compensate for domestic and regional demands, the peel (albedo) of the “non-comestible” fruit of Poncirus trifoliata was investigated using a relatively simple experimental design for optimization, in which only the variable was the extraction pH (1.0, 1.5, and 2.0) on the basis of our previous studies on diverse pectin sources. ...
متن کاملOptimization of microwave assisted extraction of pectin from orange peel.
In this study, microwave-assisted extraction was applied for pectin extraction from the dried orange peel and Box-Behnken response surface design was used to study and optimize the effects of processing variables (microwave power, irradiation time, pH and solid-liquid ratio) on the yield of pectin. The amount of pectin extracted increased with increasing microwave power, while it reduces as the...
متن کاملOptimization of Process Conditions for Pectin Extraction from Citrus Peel
Pectin is a complex polysaccharide and natural food additive extracted from citrus peel and apple pomace in the form of brownish powder. It is widely used as a jelling and thickening agent and the food industry especially in jams and jellies. It is also recommended for use as fat replacer and also lowers blood cholesterol by increasing viscosity in the intestinal tract thus lowering cholesterol...
متن کاملOptimization of Pectin Extraction from Passion Fruit Peel using Response Surface Methodology
Pectin from passion fruit peels was extracted using citric acid extraction. The effects of citric acid concentration from 0.05 to 0.21 % (wt/wt), extraction time from 30 to 120 minutes and extraction temperatures from 35 to 85 ̊C on pectin yield and the degree of esterification (DE) were investigated. Using the central composite design (CCD), the optimized pectin yield was 6.44 % and degree of ...
