The key principles in production liquor tasting covered observing liquor color,smelling liquor flavor,tasting liquor taste,and understanding liquor styles.

The Advantages of Using Immobilized Yeast in Ethanol Production from Molasses;

The application of CIP system in each step of the beer production was introduced in detail and compared with other cleaning method.

Paper method is proved a convenient, rapid and simple way in detecting and monitoring semi-products and wash water in beer production and is helpful for controlling biological contamination in beer and improving the beer qualit

In the light of existing situation in beer production,such as high water consumption,large sewage discharge,the each link including malk-making,saccharifying,fermenting and pouring is analyzed,the program that save water and reduce sewage discharge is proposed.

The research on biological purification of sewage treatement system in liquor production had been done by use of microbiological theories.

To ensure safe liquor production in Summer,regulation of production techniques and technical parameters and fermentation period should be done in advance in late spring,which could create favorable conditions for trans-production in Autumn.

Concretely,the application of"Yantai Liquor-making operation","Sichuan glutinous sorghum Xiaoqu liquor production techniques"and"raw materials substitute"has remarkable effects on improving liquor yield and saving grains;the merchan-d.

The formation of methanol(pectic substance in raw materials hydrolyzed into methoxyl group during heating and cooking and further deoxidized into methanol) occurred throughout beet molasses processing and alcohol production.

Some volatilizable substances such as methanol in steam can come into product directly,and influence product greatly if the factory adopts traditional heating method in alcohol production.

The separator for the fusel oils can not only increase alcohol quality, but also recycle diluted alcohol and the fusel oil to improve the ability for recycling rubbish and reduce the pollution in alcohol production, at the same time, it will influence on the ferment work and the distillation work.
