Abstract

The invention discloses a low-temperature fermented milk as well as a raw material composition and a preparation method thereof. The raw material composition of the low-temperature fermented milk comprises raw material milk, a sweetener, a thickener, fermentation bacteria and 0.001%-0.006% of probiotics, and does not contain a preservative, wherein the percentage of the raw materials is the mass ratio of the raw material composition of the low-temperature fermented milk, and the probiotics are lactobacillus casei LC2W. The preparation method comprises the following steps: (1) uniformly mixing the raw material milk with the temperature of 40-45 DEG C, the sweetener and the thickener; (2) homogenizing emulsion obtained in the step (1) and pasteurizing; (3) cooling emulsion obtained in the step (2), uniformly mixing with the fermentation bacteria and the probiotics, and fermenting to obtain curd at the temperature of 35-42 DEG C; (4) overturning a vat for cooling, and pumping into a storage vat; (5) filling and sealing. According to the low-temperature fermented milk, the shelf life of the low-temperature fermented milk is remarkably prolonged, relatively high viable bacterium level is maintained, and meanwhile, the specific taste and nutrition of the fermented milk are kept.

Description

technical field [0001] The invention belongs to the field of fermented milk product processing, and in particular relates to low-temperature fermented milk with long shelf life, its raw material composition and its preparation method. Background technique [0002] With the continuous improvement of living standards, people's awareness of healthy eating has gradually increased. In various nutritious diets, fermented milk is widely consumed due to its variety of flavors and textures, high-quality protein and active probiotics and other nutrients. While enjoying delicious food, it can improve body functions and regulate intestinal flora. favored by those. [0003] Through the analysis of the current fermented milk market, it is found that most of the low-temperature fermented milk has a shelf life of less than one month. The length of the shelf life is limited by various factors such as the intensity of heat treatment, the hygienic conditions of the filling process, the stora...
