摘要:

将不同霉菌、酵母菌、细菌以及食用菌用于豆渣固态发酵,筛选出食用菌农平1号用于豆渣固态发酵。以蛋白质含量和氨基酸态氮含量为评价指标,通过单因素试验和响应面法的Box-Behnken试验优化农平1号固态发酵豆渣的工艺参数,并结合操作可行性,确定最优发酵条件为:豆渣初始pH 7.5、接种量10.5%、培养温度30.5 ℃、培养时间13 d。采用该条件进行发酵实验,每100 g干豆渣的氨基酸态氮含量为3.34 g,达到预测值的97.02%,蛋白质含量为33.86 g,是预测值的98.98%。结果表明,实测值与理论值之间具有良好的拟合度。

Abstract:

Different molds, yeasts, bacteria and edible fungi were separately used for the fermentation of okara, and
Pleurotus ostreatus Nongping 1 was screened out. The fermentation conditions were optimized by single factor method
and response surface Box-Behnken design. Considering operational feasibility, the optimal fermentation conditions were
determined as okara initial pH 7.5, inoculum amount of 10.5%, fermentation temperature of 30.5 ℃, and fermentation time
of 13 d. Under these optimal conditions, the content of amino acid nitrogen in dry fermented okara was 3.34%, which was
97.02% as compared to the predicted value, and the content of crude protein was 33.86%, which was 98.98% of the predicted
value. These results showed that the experimental values were in good agreement with those predicted.

Key words: okara, Pleurotus ostreatus Nongping 1, solid-state fermentation, amino acid nitrogen
