Compound prebiotic and application thereof

Abstract

The invention relates to a compound prebiotic, which is composed of the following components by weight percentage: 30-70% of long-chain inulin, 15-40% of galactooligosaccharides, and 15-40% of fructooligosaccharide. The long-chain inulin is formed by polymerization of 10-60 fructose units. long-chain inulin is introduced into the compound prebiotic product of the invention, and achieves compatibility and combination with fructooligosaccharide and galactooligosaccharides, so that the product can ferment in ascending colon, descending colon and other areas, can act on the whole large intestine comprehensively, has flora optimization function, and also can promote bacterial metabolism, can promote calcium absorption, increase the body immunity, improve resistance to infection, and has cancer risk lowering and other functions significantly higher than other prebiotic products. The compound prebiotic product provided by the invention can be used as the raw material or ingredient of beverages, ordinary food, health food, special medicinal purpose formula food and drugs.

Description

technical field [0001] The invention relates to a composite prebiotic, in particular to a composite prebiotic composed of long-chain inulin compatible with galacto-oligosaccharide and fructo-oligosaccharide, and also relates to the anti-tumor effect of the composite prebiotic. Background technique [0002] Prebiotics are a dietary fiber that is lost in modern diets and is beneficial to human health. It is a food ingredient that can be selectively fermented to change the composition and activity of beneficial bacteria in the gastrointestinal tract that are beneficial to the host's health. Prebiotics must meet three conditions: 1. Acid-resistant and hydrolytic enzymes, not digested and absorbed by the stomach and small intestine; 2. Can be fermented by intestinal flora; 3. Can selectively stimulate intestinal beneficial such as bifidobacteria and lactobacilli bacteria growth. [0003] At present, prebiotics that are widely used are mainly oligosaccharides, such as galacto-oli...

AI Technical Summary

Problems solved by technology

[0005] 2. At present, most prebiotic products on the market are based on unilateral prebiotics, but the unilateral products have great limitations; or a very small dose of prebiotics and probiotics are combined to form synbiotic products, but the content of prebiotics in such products Too little is difficult to achieve the proper physiological functions, all because different prebiotics have their own unique characteristics (such as different promotion effects on various probiotics; different inhibitory abilities to various harmful bacteria; different fermentation times) , resulting in different activities in each area of ​​the large intestine; the types and amounts of short-chain fatty acids produced during fermentation and decomposition are different, etc.)
