摘要
黄酒酒糟是黄酒生产得到的副产物,经过第一次发酵后得到。发酵后的酒糟中蛋白质含量高达26.7%、淀粉含量高达29.96%,为使酒糟得到进一步的利用,本实验将甜酒糟进行二次发酵处理并进行优化,经过优化后得到风味物质提高效果优异,当加水量为65 m L、加酶量为1%、加菌量为10%时,发酵得到风味物质最多,为3220.14 mg/L。
Yellow rice wine lees is the by-product after the first fermentation in yellow rice wine production. Its protein content is as high as 26.7 % and its starch content is up to 29.96 %. In order to make full use of the lees, in the experiment, yellow rice wine lees was used for secondary fermentation and the fermentation process was optimized as follows： water adding level was 65 mL, the add- ing level of enzyme was 1%, and bacteria adding level was 10 %. Under the above conditions, the content of flavoring substances reached the maximum as 3220.14 mg/L.
