摘要
比较了酸性蛋白酶和无机氮源对酒精发酵速度和产率的影响,发现在较短的发酵时间内,酸性蛋白酶能更有效的强化发酵过程。同时也考察了添加酸性蛋白酶对DDGS品质的影响,结果表明酸性蛋白酶的使用并不减少DDGS的蛋白含量,而且增加蛋白质含量。
The effects of the addition of acid protease and inorganic salts on the yield and rate of alcohol fermentation were investigated in this paper. The results showed that the acid protease is more effective to fortify the fermentationtime. The quality of DDGs when adding acid protease was also studied and found out that the protein content of the DDGS was not reduced but increased.
