Abstract

The invention discloses a probiotic double-layer microcapsule and a preparation method thereof. The prepared probiotic double-layer microcapsule is not dissolved in a stomach and small intestines, andis degraded within 20 min after reaching large intestines, so that probiotics can be better colonized in intestinal tracts, further improve the intestinal environment of a host and be beneficial to intestinal health. Resistant starch is added as a probiotic, the survival rate of bacteria is significantly improved and the tolerance of the probiotic in the gastrointestinal environment is enhanced.The microencapsulation is performed for two times, microcapsules having a multi-layer system are established, the shortcomings of conventional single-layer microcapsules that easily lose water are overcome, the stability of the microencapsules is enhanced, and the microencapsules play a better role in various probiotic products; the microencapsules can better protect the bacteria, prolong the storage period of the bacteria by at least twice or more, have good dispersity and solubility in the intestinal tracts, and are suitable for storage in air/liquid multi-environments and addition in different types of food.

Description

technical field [0001] The invention belongs to the technical field of probiotic products, and relates to a probiotic double-layer microcapsule and a preparation method thereof, and relates to the effect of resistant starch as a prebiotic. Background technique [0002] Probiotics are a general term for a class of active microorganisms that colonize the intestinal tract of humans or animals and exert beneficial effects on the host. The common ones are lactic acid bacteria, bifidobacteria and Gram-positive cocci, which produce some organic acids and a large amount of short-chain fatty acids (SCFA) through their own fermentation: such as acetic acid, propionic acid and butyric acid, the production of organic acids Make the intestinal tract in an acidic environment, which can effectively inhibit the growth of Escherichia coli, Salmonella and other pathogenic bacteria; short-chain fatty acids, as the source of intestinal energy, play an important role in the repair of intestinal ...
