Abstract

A preparation method of additive-free normal-temperature yoghourt comprises the following steps: uniformly mixing 88-95% of pre-sterilized non-antibiotic milk, 4-8% of a sweetener and 1-2% of starch,homogenizing, and pasteurizing the homogenized liquid; cooling the sterilized mixed liquid, fermenting by adding a starter culture which accounts for 0.003-0.009 wt% of mass of the mixed liquid, and carrying out demulsification when acidity reaches 79-90 degree T; homogenizing and carrying out pipe sterilization, and cooling to 20-35 DGE C after sterilization to obtain the product. According to the normal-temperature yoghourt, mass content of total protein and fat is 2.5-3.0 wt%, mass content of carbohydrate is 6.6-11.8 wt%, acidity is 70-80 degree T, and viscosity is 500-700 cP. A burden sheet of a present normal-temperature fermented dairy product is simplified, the burdening of a product only takes 4-5 min, and no stabilizing agent is added. The product prepared in the invention has cream mouthfeel, is smooth and refreshing, and can be placed at normal temperature for 6 months. Microorganisms of the product accord with national standards within the shelf-life. The product has stableperformance and there is no layering or whey separating phenomenon.

Description

technical field [0001] The invention belongs to the technical field of fermented milk products, and in particular relates to a normal temperature non-added fermented milk and a preparation method thereof. Background technique [0002] Normal temperature fermented dairy products are favored by dairy processors and consumers because of their unique taste and flavor, no need for refrigeration, and convenient logistics, transportation and storage. Although fermented milk products at room temperature do not contain live bacteria, according to the conclusion of the World Dairy Federation (IDF) on fermented yogurt, the metabolites produced during the fermentation of yogurt have unique nutritional value and are the core of the nutritional value of fermented milk. It does not depend on the activity of lactic acid bacteria after the fermentation is completed. A large number of studies have shown that most of the lactic acid bacteria in traditional fermented milk are killed by gastric...
