Preparation method of probiotic microcapsules for feed

Abstract

The invention provides a preparation method of probiotic microcapsules. The probiotic microcapsule is composed of wall material, Lactobacillus plantarum, stachyose, and Morchella enzymolysis powder. The method for coating the probiotic microcapsule product is as follows: adding 3-5% stachyose and 5-8% morel enzymolysis powder to the probiotic fermented liquid after fermentation in the fermenter , and then the fermented liquid is mixed with the wall material solution to obtain a mixed solution; the method of ultrasonic vacuum spray drying is adopted, first-level vacuum drying, second-level inert protective gas plus vibration fluidized bed drying, and microcapsule coating of probiotics. The capsule of the invention adopts modified soybean protein isolate and has good enteric solubility. After the capsule reaches the intestinal tract, it can completely disintegrate and release probiotic bacteria within 1-1.5 hours, and rapidly proliferate into a dominant flora, thereby inhibiting the growth of pathogenic bacteria. and so on. In the present invention, the enzymatic hydrolysis powder of Morchella is used, so that the product has both the nutritional properties of Morchella, has good palatability, and improves the feeding effect of animals.

Description

technical field

[0001] The invention relates to a preparation method of probiotic capsules, belonging to the technical field of microbial feed additives. Background technique

[0002] Lactic acid bacteria microecological feed additives are an important alternative to antibacterial drugs. Lactic acid bacteria are one of the outstanding representatives of beneficial bacteria in the normal intestinal flora, and have important physiological and health functions: they can antagonize pathogenic microorganisms, regulate the balance of animal digestive tract microflora: activate the immune system, enhance immunity, prevent various The occurrence of diseases and adverse reactions; inhibit the occurrence of tumors, protect the health of animals; synthesize nutrients, produce digestive enzymes, improve the activity of animal digestive enzymes, improve the metabolism of vitamins, neutralize enterotoxins, and reduce the harmful substances such as amines and ammonia. produce etc. Howeve...
