PRODUCTION OF AQUEOUS BETA-GLUCAN FROM BARLEY BRAN

摘要

The extraction method of soluble beta-glucan (I) from barley bran consists of (1) soaking barley bran in 70-95% ethanol to inactivate beta-glucanase, (2) separating brans, (3) hydrolysing proteins of bran with papain at 30-50 deg.C for 1-2 hrs, (4) adding 1-2 volume of 70-95% ethanol to crystalize (I), and (5) vacuum drying. (I) is useful as dietary fibers.
