超声波协同酶法提取大豆多糖工艺的研究
Ultrasonic-Assisted Enzymatic Hydrolysis of Bean Dregs for Extraction of Polysaccharides
摘要
Abstract
The present study aimed at developing an optimal procedure for the extraction of polysaccha-rides from the bean dregs hydrolyzed with a commercial cellulase preparation under ultrasonic assistance. The optimal values of crucial technological parameters for improved polysaccharides yield were determined by one-factor-at-a-time and orthogonal array design methods as follows; ultrasonic powder 200 W for 30 min treatment,material/water concentration is 0.04 g/mL, enzyme dosage 1.5%, pH 5.0 and hydrolysis temperature 50 ℃ for a hydrolysis duration of 40 min. Under such conditions, a maximum polysaccharides yield of up to 12.23% was obtained.关键词
