Structure and rheological properties of a xyloglucan extracted from Hymenaea courbaril var. courbaril seeds.
Hymenaea courbaril var courbaril seed xyloglucan was efficiently extracted with 0.1M NaCl, followed by ethanol precipitation (yield=72±5% w/w). Its amorphous structure was identified by the pattern of X-ray diffraction. The monosaccharide composition was determined by GC/MS analysis of the alditol acetates and showed the occurrence of glucose:xylose:galactose:arabinose (40:34:20:6). One-(1D) an...
متن کاملSome Physicochemical and Rheological Properties of Zedo (Farsi) Gum Exudates from Amygdalus scoparia
Background and Objectives: Zedo gum is exuded in three colours (white, yellow, and red) from Amygdalus scoparia. It is used in both food and non-food industries, as well as in traditional medicine. This study aimed to determine the physicochemical and rheological properties of Zedo gum. Materials and Methods: Zedo gum was collected in Sirjan and classified into three groups, based on colour ...

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 اولStudies on Leucaena Leucocephala Seed Gum: Rheological Properties
The apparent viscosity (pseudoplastic viscosity) of mucilage of leucaena seed gum was calculated, based on flow curves, obtamed With multiple point viscometer. Attempts were made to correlate the various rheological properties, describIng the_ overall flow behaviOur of gum, with their concentrations. The relationship between N(exponential constant) and concentration was found to be a zero order...
متن کاملA New ent-Clerodane Diterpene from Hymenaea courbaril var. altissima
Da casca do tronco de Hymenaea courbaril var. altissima (Ducke) foi isolado um novo entclerodano na forma de éster metílico, após esterificação com diazometano, o (-)-(5R,8S,9S,10R)clerod-3-en-15-oato de metila. Foram isolados também dois ent-labdanos conhecidos: o (-)-copalato de metila e (-)-eperuato de metila. Do extrato AcOEt do epicarpo foi isolado, após esterificação com diazometano, o (-...
