Problems solved by technology

[0005] At present, the products related to probiotics are generally applied in the field of medicine, such as compressed tablets, capsules, powders, etc., generally need to be stored in low temperature refrigeration, and the storage environment is limited. Therefore, the application field is very limited
[0006] 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 preparation method of probiotic microcapsules and the probiotic microcapsules prepared by the method. A method combining extruding granulation with spraying granulation through a fluidized bed is adopted. The preparation method comprises the following steps of: (1) performing coating of first-layer microcapsules; (2) optionally performing coating of second-layer microcapsules; and (3) optionally performing continuous coating for the third time or more times on the microcapsules obtained in the step (2).

Description

[0001] References to related applications [0002] This application claims the priority of Chinese Patent Application No. 201811314763.8 filed on November 6, 2018, and the entire content of the application is incorporated herein as a part of the description. 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. However, during actual production, storage, and transportation, probiotics are affected by food components (acids, additives, etc.), ambient temperature, and host digestive system (gastric acid, enzymes, bile salts, etc.), resulting in a significant drop in the number of viable bacteria , the number of viable bacteria that f...
