入房大曲不发酵原因及技术措施

入房大曲不发酵的主要原因有：①环境温度过高，杀灭了有益微生物；②环境温度过低，抑制了微生物的生长；③药物污染，对微生物产生杀灭作用。解决办法：一是控制曲房环境温度，搞好室内卫生，抑制杂菌污染；二是加入１％～２％母曲粉强化发酵；三是对曲房采取升温保温措施，保证起始品温在１５～２０℃；四是把好制曲原料关，加强原料检测，不用受农药污染的粮食原料。（一平）

The Unfermentable Reasons of Daqu in the Fermentation Room and the Technical Measures

The unfermentable reasons of Daqu set in the fermentation room were:The temperature of environment was too high,the beneficial microbe was killed.The temperature of environment was low to inhibite the microbe growing.The contamination of chemicals had the action of sterilizing.The technique measures of solving the problems are as following.The first measure was controlling the temperature of environment in the fermentation room.The environment sanitation was done well to inhibite hetero-bacterium contamination.The second measure was fortifying the fermentation by adding 1%2% mother koji powder.The third measure was rising and keeping the temperature in the fermentation room to ensure the original temperature of koji at 1520.The fourth measure was guarantee the quality of koji-making material.The detection of material was intensified.The grain material of pesticide pollution couldnt be used.
