Problems solved by technology

[0007] The application of probiotics in the field of food and even dairy products is generally used as a starter to prepare low-temperature refrigerated products. On the one hand, the storage environment has great limitations. On the other hand, these probiotics are affected by gastric acid and enzymes. It leads to a sharp decrease in the number of probiotics that finally enter the intestinal tract and cannot effectively exert their probiotic effects
[0008] In addition, in the field of dairy products, probiotics are added to the products. The embedding technology usually adopts colloid-embedded probiotics, which are in the form of glue drops, and are directly added to the product. However, due to the influence of the production process, the probiotics in the final product The number of bacteria is kept less, and the application conditions are relatively harsh

Abstract

The invention relates to a probiotic microcapsule and a preparation method thereof.

Description

[0001] References to related applications [0002] This application claims the priority of Chinese Patent Application No. 201811314766.1 submitted on November 6, 2018, and the entire content of the application is incorporated herein as a part of the specification. technical field [0003] The invention belongs to the field of food biotechnology. More specifically, the present invention relates to a probiotic microcapsule and a preparation method of the probiotic microcapsule. Background technique [0004] Probiotics, as a kind of living microorganisms that can promote the health of the host, have multiple physiological functions in treatment and health care. Ordinary probiotics such as lactic acid bacteria are relatively fragile and are easily affected by surrounding environmental factors. Therefore, ordinary probiotic products need to be stored in low temperature refrigeration, so as to ensure the maximum number of active probiotics and increase the number of colonies over...
