Prebiotic composition, synbiotic composition and application thereof

Abstract

The invention relates to the technical field of biotechnology, in particular to a prebiotic composition, a synbiotic composition and application thereof. The prebiotic composition contains solid sialic acid and a pH regulator, and the final pH value of a 1% (w / v) prebiotic composition aqueous solution is 5.0-7.5. The synbiotic composition contains probiotics and the prebiotic composition, and the probiotics are dry thalli and / or an embedded dry thalli compound. According to the invention, the survival rate of probiotics can be guaranteed, the effect of sialic acid can be reflected, which is beneficial to guide and promote the solid-state application of sialic acid. Meanwhile, the scheme is simple and convenient, raw material loss is small, which is conducive to controlling costs and improving the market competitiveness of products.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a prebiotic composition, a synbiotic composition and applications thereof. Background technique [0002] Synbiotics generally consist of probiotics and prebiotics. Among them, probiotics are a kind of active microorganisms that are beneficial to the host. They are a general term for active beneficial microorganisms that colonize the human intestinal tract and reproductive system and can produce definite health effects to improve the host's micro-ecological balance and exert beneficial effects. It is a kind of oral beneficial live bacteria preparation, but in the process of production, transportation, storage, etc., probiotics will be affected by many factors, resulting in a significant drop in the number of live bacteria. A prebiotic is an inanimate food ingredient that can benefit the health of the host by regulating the microbial flora. It is a kind of beneficial bacteria that is ...

Problems solved by technology

However, most of the research directions on probiotics focus on solid powder preparations. Sialic acid is an excellent prebiotic that probiotics can use, and the supplement of a certain dose of sialic acid is also positive for human nutrition, but , the applicant found in the research that when sialic acid is directly mixed with probiotics, it will have a killing effect on the probiotics and greatly damage the survival rate of the probiotics. This phenomenon not only affects the cost of the product but also affects the product cost. Stability during storage, which becomes a major obstacle for the application of sialic acid as a prebiotic
