应用普鲁兰酶提高黄酒残糟出酒率的研究

Research on the Application of Optymix L-1000 to Improve the Liquor Yield of Residual Distiller's Grains of Yellow Rice Wine

通过对普鲁兰酶加糖化酶、淀粉酶加糖化酶和只加糖化酶3种工艺的研究和试验比较,根据醪液中还原糖和总糖变化及发酵情况等,得出:采用普鲁兰酶和糖化酶工艺对黄酒残糟的利用效果明显,操作简单,特别适用于类似像黄酒残糟含大量支链淀粉的原料,若配以纤维素酶使用,更能提高出酒率,提高综合经济效益,实现清洁生产。

Three technical measures （Optymix L- 1000 plus saccharifying enzyme, amylase plus saccharifying enzyme, saccharifying enzyme only） were compared in the experiment. Through the analysis of the changes of reducing sugar and total sugar and the fermentation process, it was concluded that the technical measure ofOptymix L-1000 plus saccharifying enzyme was the best measure to make full use of residual distiller＇s grains of yellow rice wine （its simple operation was especially suitable for residual distiller＇s grains containing large amount of amylopectin）. Such measure coupled with the use of cellulose would greatly improve liquor yield and realize sanitary production, which could increase comprehensive e- conomic benefits of the enterprises.
