Abstract

The invention provides probiotic microcapsules with protein aggregate-polysaccharide as the wall material and a preparation method thereof. The preparation method is as follows: rice bran protein forms an aggregate and a polysaccharide solution at a low pH according to a certain volume ratio (1:1-10 : 1) Mix, add probiotic bacteria suspension and an appropriate amount of emulsifier (Tween-80) to the formed mixture and stir gently until a stable emulsion is formed, add 1% acetic acid under constant stirring The final pH of the solution is 3.8-4.0 in the mixed solution, and finally a curing agent (gallic acid) is added to solidify the microcapsules, and then washed with distilled water to finally obtain a probiotic microcapsule product. The present invention only needs to control the ratio of protein aggregates and polysaccharides and the crosslinking time to achieve the purpose of crosslinking. The prepared microcapsules of probiotics can improve the resistance to gastric acid, and finally release the probiotics in the intestinal tract. It is absorbed by the human body and has good storage properties.

Description

technical field

[0001] The invention belongs to the field of food biotechnology, and in particular relates to a probiotic microcapsule product with rice bran protein aggregate-polysaccharide composite gel as wall material and a preparation method. Background technique

[0002] Microcapsule technology is a technology that embeds solid, liquid or gaseous substances that are sensitive to the surrounding environment in capsules and can release them in a controlled manner in a specific environment. The size of microcapsule particles generally varies due to different processing techniques, and the particle size range is generally 0.1-1000um. Microcapsules are divided into two parts: wall material and core material. The material embedded in the microcapsule is called core material, and the material embedded outside is called wall material. Wall material is generally natural polymer material, semi-synthetic polymer material materials, fully synthetic polymer materials and inorganic...
