产品介绍


Product Describtion:

β- - AMYLASE A304857 A304857 is a preparation of purified β-amylase obtained from soybean. β- amylase hydrolyzes α-1, 4 glycosidic linkage in starch and glycogen with an inversion of configuration about C(1) position of glucose from α to β. A304857 is more stable than the corresponding enzymes from wheat and barley malt, and is suitable to produce high maltose syrup from starch. The product consists of 40% β -amylase and 60% Corn starch.
