Changes of superoxide dismutase activities in barley during the process of malting and storage;

The microorganism of its surface or the outside source has long been associated with the quality of malt in process of malting and the product of beer.

Control of mold and effects of barley microbe on malting and brewing;

"Xiajiang aged winter wine",which was took Zaojian glutinous rice harvested in the same year as raw material,was brewed using home-made starter and stepped raw wheat koji as starter.

Basic definition of conventional raw wheat koji-making,types and source of microorganisms in raw wheat koji and the features and function of microbial system,enzymatic system and substance system including in raw wheat koji were introduced.

This article introduces the automatic control system of wort preparation, the system with the core of programmable logical controller and the intelligent control algorithm and PID algorithm can effectively control the temperature, the pressure, the converter, the valve, the motor in order to realize the automatic control system of wort preparation.

It was mainly researched for the wort preparation process of high-accessories beer in this paper, including the selection of raw materials and enzyme, hydrolysis craft of raw materials and accessories and saccharification process.
