摘  要:
研究混菌固态发酵的工艺条件;以豆粕的可溶性蛋白和大豆球蛋白含量为评价指标,设计菌种添加量、发酵时间、发酵温度、初始含水量、外源酶的添加量、初始p H值等6个因素,进行单因素和正交试验;单因素试验确定菌种添加量为4%,初始p H值为6.5,正交试验得出:发酵时间为7 d、发酵温度40℃,初始含水量为40%,外源酶的添加量为0.45%,该条件下可溶性蛋白的含量为168.5μmol/g,大豆球蛋白的含量为11.2μmol/g,效果理想,为豆粕固态发酵的应用提供参考。

摘  要:
Technology conditions of solid-state fermentation with multi-strains was studied in the paper. Content of soluble protein and glycinin of soybean meal were as evaluation indexes. The inoculumsize, fermentation time, fermentation temperature, initial moisture content, adding amount of exogenousenzyme and initial p H were designed through the single-factor tests and orthogonal test. The results oforthogonal test show the fermentation time is 7 days, fermentation temperature is 40 ℃, initial mois-ture content is 40%, adding amount of exogenous enzyme is 0.45%. Under this condition, the contentof soluble protein is 168.5 μmol/g and glycinin is 11.2 μmol/g. These provided a reference for the application of fermented soybean meal.
