Problems solved by technology

In order to solve the problem of low survival rate and instability of probiotics in use, the use of microcapsule embedding technology to protect probiotics has become a hot research topic at home and abroad.
However, most of the existing microcapsule coating technologies and products have the problem of surface porosity, especially the single-layer microcapsules have a pore size of 500-900 nanometers, and the stability is not good. After entering the human or animal digestive tract, most It is difficult to withstand the effects of gastric acid, bile acid and pancreatic juice with low pH value; when applied to livestock and poultry feed, it is difficult to withstand the high temperature and high pressure impact of feed pelleting; unable to meet requirements
In addition, some technical processes are not suitable for large-scale production, which seriously affects the activity of the coated probiotics and the industrialization and application of their products

Abstract

The invention discloses a preparation method of multi-layer coated probiotic microcapsules. The preparation method includes coating the probiotics before microencapsulation and coating after fermentation, so as to prepare multilayer composite coated probiotic microcapsules. The preparation method of the invention plays a great role in maintaining the survival and stability of the probiotic preparation. In addition, the preparation method of the present invention can more conveniently realize the large-scale production of probiotic microencapsulated products, and is suitable for the preparation of probiotic microcapsules in various fields such as feed, food, and medicine.

Description

technical field [0001] The invention belongs to the technical field of microorganisms. More specifically, it relates to a preparation method of multi-layer coated probiotic microcapsules. Background technique [0002] The function of live probiotic preparations mainly depends on the life activities of the live bacteria contained in them. Therefore, the content of live bacteria, the vitality of live bacteria and the length of shelf life are the key factors to evaluate the quality of products. At present, researchers at home and abroad regard maintaining the survival and stability of probiotic preparations as the standard for quality evaluation. In order to solve the problem of low survival rate and instability of probiotics in use, the use of microcapsule embedding technology to protect probiotics has become a hot research topic at home and abroad. However, most of the existing microcapsule coating technologies and products have the problem of surface porosity, especially t...
