• 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℃
