Application of Raw and Mature Wheat Kojis in the Clarifying Liquid Process

采用单因素多水平的实变化特点,对提高白酒酒质稳定性有重要作用。

Through the experiment, the differences in the saccharification, fermentation and the quality of the product during yellow rice wine production with clarifying liquid technology, due to the rawand mature wheat kojis, were compared. The abilities of liquefying, saccharifying and protein hydrolysis of the raw wheat koji were lower, however the contents of high and medium molecular weight sugars were higher than that of mature wheat koji. The nutrition of saccharifying liquid with mature koji was better, the trigger of fermentation was rapid, and the fermentation was relatively completely. Whereas the organoleptic quality of the wine fermented by the raw wheat koji was better, the content of alcohol was lower. The mixture of raw and mature kojis is suitable for the rice wine production with clarifying liquid process.
