一种食品级中温α‑淀粉酶的生产方法
摘要：
本发明提供了一种食品级中温α‑淀粉酶的生产方法，包括如下步骤：1)中温α‑淀粉酶发酵液的制备；2)絮凝处理；3)过滤处理；4)一次浓缩处理；5)除菌处理；6)二次浓缩处理；7)真空低温干燥处理；8)整粒。该方法采用真空连续低温干燥的方法制得食品级中温α‑淀粉酶制剂，其酶活性高，流动性好，溶解速度快，无杂菌污染，生产过程无粉尘，而且操作简单，投资成本低，可连续化生产，具有良好的市场应用前景。
摘要（英）：

The invention provides a method for producing food-grade medium temperature alpha-amylase. The method comprises the following steps: 1) preparation of a medium temperature alpha-amylase fermentation broth; 2) flocculation treatment; 3) filtering treatment; 4) primary concentration treatment; 5) sterilization treatment; 6) secondary concentration treatment; 7) vacuum low-temperature drying; and 8) granulation. The method adopts a vacuum continuous low-temperature drying technology to prepare the food-grade medium temperature alpha-amylase. The food-grade medium temperature alpha-amylase has the advantages of high enzyme activity, good fluidity, fast dissolving speed and no living contaminants, and the method has the advantages of dust-free production process, simplicity in operation, low investment cost, realization of continuous production, and good market application prospect.
