Abstract

The invention provides a method for maintaining the number of living bacteria in sour milk or an active lactobacillus beverage, relates to new applications of Rhodiola rosea, and concretely relates to applications of Rhodiola rosea in the maintenance of the stability of the number of living bacteria in sour milk or the active lactobacillus beverage within a shelf life, and/or in the inhibition of the increase of the acidity of sour milk. The invention also provides a making method of Rhodiola rosea-containing sour milk, and a making method of the active lactobacillus beverage. The sour milk and the active lactobacillus beverage are respectively adopted as a carrier, Rhodiola rosea is added, and the total number of lactobacillus in the obtained sour milk or the active lactobacillus beverage is constant; and after the fermentation acidity of the sour milk reaches about 130DEG T, the increase of the acidity of the sour milk is inhibited. A reasonable formula and an appropriate technology enable the obtained sour milk and the active lactobacillus beverage to have a good flavor, a good mouthfeel and a good living bacterium stability within the shelf life.

Description

technical field [0001] The invention belongs to the field of fermented dairy product processing, and in particular relates to a method for adding rhodiola rosea to yogurt and active lactic acid bacteria beverages to maintain the stability of the number of viable bacteria in the shelf life of the yogurt and active lactic acid bacteria beverages, and to inhibit the growth of the acidity of the yogurt. Background technique [0002] Yogurt and active lactic acid bacteria drinks are very popular because they are rich in nutrition and can regulate the intestinal flora in the body. The functionality of yogurt and active lactic acid bacteria drinks mainly depends on the number of viable bacteria in yogurt and active lactic acid bacteria. How to keep the number of viable bacteria from decreasing significantly during the shelf life has always been the focus of attention in the dairy industry. [0003] Rhodiola rosea (Rhodiola rosea, English name Roseroot) is a perennial herb or shrub...
