Abstract

The invention provides fermented milk without food additives and a preparation method thereof. The fermented milk without the food additives comprises 86%-93.7% of raw milk, 0.2%-1% of milk protein powder, 0.1%-5% of single cream, 6%-8% of sugar and a fermentation strain of 4* 106-1.5*108 cfu/g. The fermentation strain comprises lactobacillus bulgaricus, streptococcus thermophilus and lactococcus lactis. The preparation method comprises the steps that 1, the milk protein powder, the sugar and the single cream are added to the preheated raw milk to be stirred; 2, homogenizing, sterilizing and cooling are conducted; 3, the fermentation strain is added, and fermentation is conducted for 3-5 hours at the temperature of 25-35 DEG C; 4, fermentation is conducted at the temperature of 37-45 DEG C until the degree of acidity reaches 70-80 oT; 5, cooling and instant cold storage are conducted, and then post-maturation is conducted for 12-24 hours. By the adoption of the preparation method of the fermented milk without the food additives, the fermented milk has strong milk flavor, and the possibility of the bleeding phenomenon during the shelf life is reduced.

Description

technical field [0001] The invention relates to the field of dairy products, in particular to a food additive-free fermented milk and a preparation method thereof. Background technique [0002] Conventional commercial fermented milk improves the texture of the product by adding a thickener to avoid the phenomenon of water separation and other quality-affecting products during storage; the product is given a strong milky flavor by adding flavors, and some fermented milk is given by adding pigments. Products vary in shade. However, affected by frequent incidents of illegal use of additives in recent years, consumers are very sensitive to additives such as thickeners, essences, pigments, and preservatives, and urgently need fermented dairy products with the least ingredients and the cleanest labels. [0003] In order for yogurt to maintain good viscosity and thick taste without adding stabilizers, its protein content generally needs to be above 4.0%. In the Chinese patent "Fo...
