The technology of medium temperature α-amylase hydrolyze Huaiqing yam
This paper studied the technological conditions of medium temperature α-amylase hydrolyze Huaiqing yam.With yield rate of soluble solids,on the base of single test factors,it determined the optimum technological conditions of medium temperature α-amylase by orthogonal experiments.The results show that temperature was the most important factor affected the result,following with pH and the amount of enzyme.The effect of time was not obvious in our study.The optimal conditions:dosage of enzyme 0.060 mg/mL,pH 7,temperature 80 ℃ and time 20 min.Under this condition,the yield of soluble solid was 24.259%.
