糖化酶在大曲酒生产中的应用研究

本法是将传统大曲酒生产工艺(续渣混蒸法)中的撒曲步骤改为加糖化酶,加酶量按砖曲用量折算。由于在大曲酒生产中应用糖化酶,因此提高出酒率9.3％。操作简单、方便,不改变传统工艺流程。有明显经济效益。

STUDIES ON APPLICATION OF GLUCOAMYLASE IN PRODUCTION OF CHINESE SPIRITS

The conventional process for production of Chinese spirits consists of six steps, i. e., mixing raw materials with fermented grains, steaming the mixture in an apparatus to distil out the liquor, adding hot water, letting it cool, mixing the distillate with yeast and then putting the mixture into a pit for fermentation. But in this study glucoamylase was used to substitute yeast in the process, and the ferment obtained from residue of fermented grains. Applying glucoamlyaes to Chinese spirits-making process has been found to register an average increase of 9.3~J0 to lipuor production.
