嗜温性乳酸菌在发酵乳饮料中的应用研究

Application Research of Mesophilic Lactic Acid Bacteria Used for Fermented Milk Beverage

嗜温性乳酸菌发酵乳饮料是以牛乳、白砂糖、嗜温性乳酸菌为主要原料,经过均质、杀菌、发酵、调配糖水等加工工艺而制成的一种营养丰富、口感独特、发酵风味醇厚的活性乳酸菌饮料。试验结果表明:灭菌牛乳接种0.02%的嗜温性乳酸菌,经过31℃,14 h培养发酵,再与质量分数8%的蔗糖、0.5%的复合稳定剂混合液按照体积比3∶2调配,即可得到优质嗜温性乳酸菌发酵的乳饮料。

The main raw materials such as milk, white granulated sugar and the mesophilic lactic acid bacteria are used to make a kind of fermented milk beverage. The procedures of homogenization, sterilization, fermentation, syrup blending process are used to get a nutrient-rich, unique taste, fermented flavor mellow active lactic acid bacteria beverage. The results show that sterilized milk is inoculated 0.02% mesophilic lactic acid bacteria, and after fermentation process for 31 ℃, 14 h, mixed with 8% sucrose solution, 0.5% complex stabilizer mixture according to the volume ratio of 3 ： 2 deployment, finally the high quality mesophilic lactic acid bacteria fermented milk beverage are produced.
