Abstract

The invention discloses lactobacillus plantarum somatomedin as well as a raw material composition, a preparation method and application thereof. The raw material composition of the lactobacillus plantarum somatomedin comprises revertose, water and casein and / or whey protein. The preparation method of the lactobacillus plantarum somatomedin comprises the steps of uniformly mixing and dissolving the raw material composition of the lactobacillus plantarum somatomedin; and then, performing high temperature thermal treatment at temperature higher than 90 DEG C for more than 10 minutes. The invention further discloses application of lactobacillus plantarum somatomedin in preparing lactobacillus plantarum containing fermented milk. The somatomedin can be used as a fermenting promoter in cow milk of lactobacillus plantarum to promote lactobacillus plantarum to proliferate quickly and massively in the fermentation process of lactobacillus plantarum, thereby being favorable for application of lactobacillus plantarum in fermented dairy.

Description

technical field [0001] The invention relates to plant lactobacillus growth-promoting factor and its raw material composition, preparation method and application. Background technique [0002] Lactobacillus plantarum (lactobacillus plantarum) often exists in fermented vegetables and fruit juices, belongs to the genus Lactobacillus in the Lactobacillus family, and most of them are isolated from plants. Lactobacillus plantarum generally has an optimum growth temperature of 30°C-35°C, can grow at 10°C, but does not grow when the temperature is as high as 45°C, anaerobic or facultative anaerobic, and can grow in the pH range of 4.5-9.5. The most suitable pH value is around 6.5. Lactobacillus plantarum inhibits the growth of pathogenic bacteria by competing with the ability of pathogenic bacteria to limit nutrients, regulates the composition of intestinal microecology, and forms a biological barrier. The effects of hydrogen peroxide and diacetyl on other bacteria can regulate th...
