摘要
以酵母菌、乳酸菌和枯草芽孢杆菌作为菌种对菜籽粕进行固态发酵,测定温度和水分对菜籽粕发酵品质的影响;发酵温度为30、35、40℃,水分含量为35%和40%;结果表明,温度和水分对发酵菜籽粕品质的影响存在交互作用,发酵菜籽粕的pH、酸结合力均极显著低于未发酵菜籽粕(P<0.01),粗蛋白含量极显著高于未发酵菜籽粕(P<0.01);温度为35℃,水分为40%条件下发酵的菜籽粕pH最低,粗蛋白含量最高,酸结合力、粗纤维含量均较低,且显著低于未发酵菜籽粕(P<0.01),可作为菜籽粕发酵的适宜温度和水分。
Saccharomyces,Lactobacillus and Bacillus subtil were used as spawn to produce solid ferment rapeseed meal to study the effects of ferment temperature and moisture on rapeseed meal quality. Temperature seted 30℃, 35℃, 40℃, moisture were 35% and 40%.The results were showed that there were interaction between temperature and moisture. Compared with not fermented rapeseed meal, pH and acid-binding capacity of fermented rapeseed meal-sol were significantly reduced（P〈0.01）,crude protein content was significantly increased（P〈0.01）.Ferment temperature and moisture were 35℃ and 40%, pH was the lowest ,crude protein content was the highest, acid-binding capacity and crude fiber was lower and had significant difference compared with not fermented rapeseed meal. Optimal ferment temperature and moisture were 35℃ and 40%.
