Abstract

The invention discloses stirring type litsea coreana flavored fermented milk and a making method thereof. The raw material of the stirring type litsea coreana flavored fermented milk is composed of a component A, a component B, a component C and a component D. The component A is prepared from, by mass, 81-84% of camel milk and 8.5-12% of concentrated pear fructose. The component B is prepared from, by mass, 1-4% of bletilla root pulp, 1.5-3% of conic gymnadenia rhizome pulp and 0.5-2% of Chinese yam pulp. The component C is prepared from 0.5-1% of litsea coreana water extract frozen dry powder. The component D is lactic acid bacterium yoghurt starter, and the inoculation quantity is 2.5-3.0 g / L. The main technical index requirements of the stirring type litsea coreana flavored fermented milk conform to regulations of the national standard GB19302-2010.

Description

1. Technical field [0001] The invention relates to a stirring type flavor fermented milk product, in particular to a stirring type eagle tea flavor fermented milk and a preparation method thereof. 2. Background technology [0002] Stirred yogurt is made from mammalian emulsion or reconstituted milk. After fermented by probiotics, the emulsion is broken and other auxiliary materials are added to obtain a fermented milk product with fine and uniform texture and good flavor. With the improvement of living standards, people's functional demand for yogurt is increasing, which prompts the research of functional yogurt to attract the attention of researchers. The health-care mixed yogurt made by adding ingredients such as grains, fruit grains, vegetable juice or traditional Chinese medicine to yogurt, inoculated with lactic acid bacteria and fermented is very popular among consumers. In order to improve the antioxidant activity of yogurt, researchers added grape polyphenols, apple...
