产品介绍

 耐高温α-淀粉酶采用地衣芽孢杆菌(Bacillus licheniformis)经发酵、提取精制而成。

 

本品具有良好的耐高温特性。广泛应用于淀粉糖(葡萄糖、饴糖、糊精、果糖、低聚糖)、酒精、啤酒、味精、食品酿造、有机酸、纺织、印染、造纸及其他发酵工业等。能在较高的温度下迅速水解淀粉分子中α-1.4葡萄糖苷键,任意切断成长短不一的短链糊精和少量的低聚糖,从而使淀粉的粘度迅速下降。液化作用时间延长,还会产生少量的葡萄糖和麦芽糖。

 

温度范围:最适作用温度在90℃以上,95-97℃液化迅速,100℃仍保持相当的活力,早喷射液化时,瞬间温度可达105-110℃。

 

PH范围:有效PH范围在5.5-8.0,最适PH范围在5.8-6.5。

 

酶活定义:在70℃、PH6.0条件下,1分钟液化1mg可溶性淀粉成为糊精所需要的酶量,即为1个酶活力单位。

 

在酒精生产中,以每吨原料加入该酶0.3升左右(2万 u/g),PH6.5-7.0,搅匀以后用泵送入蒸煮锅或连续蒸煮加热器,温度可控制在100±5℃。时间为100分钟,冷却后糖化。

外观: 粉末
储存条件: 2-8℃
