摘要: 为探讨发酵豆粕生产的最适条件,本研究测定不同的菌种接种量、发酵温度、水分、发酵时间、辅料等几种因子对豆粕发酵效果的影响。结果显示枯草芽孢杆菌、酿酒酵母菌、乳酸菌的添加比例分别为3‰、2‰、1‰,蛋白酶添加量为2‰,菌种活化时间为0.5 h,发酵的初始水分为38%,温度保持在30~42 ℃时,发酵豆粕的理化指标最优,其中小肽含量可达20%以上,乳酸含量可达3.5%以上,并且质量稳定。

Abstract: To study the optimal condition of fermented soybean meal production, several factors were selected to study the effects of different strains inoculation quantity, fermentation temperature, moisture content, fermentation time and accessories on soybean meal fermentation.The results showed that when Bacillus subtilis, Saccharomyces cerevisiae and Lactobacillus addition proportions were 3‰, 2‰, 1‰, respectively, proteinase supplementation was 2‰, strains activation time was 0.5 h, initial moisture content was 38%, fermentation temperature kept at 30 to 42 ℃, physical and chemical indexes of fermented soybean meal were optimal, the contents of small peptide and lactic acid could reach more than 20% and 3.5%, respectively, and at the same time, quality of fermented soybean meal was very stable.
