根据乳酸菌和双歧杆菌的最适发酵温度存在差异的特点,进行变温发酵试验,生产双歧杆菌大豆酸奶.采用正交试验优化配方及发酵工艺条件,并测定其双歧杆菌活菌数.试验结果表明,在40℃下发酵4 h,然后降温到37℃发酵2.5 h,主发酵完成后在4℃条件下后发酵24 h.最终产品双歧杆菌活菌数达107个/mL,较同一配方恒温发酵产品增加了100倍.
根據乳痠菌和雙歧桿菌的最適髮酵溫度存在差異的特點,進行變溫髮酵試驗,生產雙歧桿菌大豆痠奶.採用正交試驗優化配方及髮酵工藝條件,併測定其雙歧桿菌活菌數.試驗結果錶明,在40℃下髮酵4 h,然後降溫到37℃髮酵2.5 h,主髮酵完成後在4℃條件下後髮酵24 h.最終產品雙歧桿菌活菌數達107箇/mL,較同一配方恆溫髮酵產品增加瞭100倍.

Temperature shift fermentation to produce bifidobacterium soybean yogurt was studied, according to the differences of the favorite fermented temperature between lactobacillus and bifidobacteriai. Based on orthogonality test, the optimum formula and fermentation process were conducted, and live Bifidobacteriai was counted. The raw materials were fermented 4 hr. in 40 ℃ at first, 2.5 hr. in 37℃ subsequently, and then in 4℃ refrigerate for 24 hr. In the final product, there were 107/mL living Bifidobacteriai, which was one hundred times than the product of the same formula, putting in the constant temperature.
