Description
Technical Field
The invention relates to the technical field of bioengineering, in particular to a method for promoting lactobacillus proliferation by using Maillard reaction products.
Background
The human intestinal tract gathers complex and diverse bacteria, and the imbalance of intestinal flora can cause inflammatory bowel disease, colorectal cancer and other metabolic diseases. A large number of clinical trials show that the intake of probiotics and prebiotics has the function of preventing and treating various common diseases of human bodies. However, the probiotic bacteria need to overcome gastric acid, bile salts and various intestinal digestive enzymes when entering the intestinal tract to exert the probiotic effect, and the probiotic bacteria have the characteristics of high survival rate and strong planting force. In contrast, a prebiotic is a non-digestible compound that modulates the composition and/or activity of the intestinal flora through metabolism of the intestinal microorganisms, thereby producing a beneficial physiological effect on the host. Therefore, the development and application of prebiotics is more universal.
Currently, the main components of the prebiotic materials that are proven are non-digestible carbohydrates, such as functional oligosaccharides, polysaccharides and natural plant extracts. The study by Sarikaya et al found that inulin could be fermented by intestinal microbial suspensions to promote the growth of lactobacilli and bifidobacteria. In addition, he Jun and other researches show that the fructo-oligosaccharide and the inulin can slow down the decay of bifidobacteria in the fermented milk, and the inulin has better effect. Studies such as Szotysik show that the dry powder of the rose extract can improve the content of probiotics in the yoghurt. These sugars can be bound, taken up or utilized by the transporters or enzymes specifically expressed by the probiotics and thus can selectively promote the growth of the probiotics. However, most of the existing prebiotic materials do not contain a protein source. Studies have shown that proteins and certain amino acids are important nitrogen sources and growth factors for the intestinal flora, since most of the ingested proteins are absorbed by the small intestine, resulting in a deficiency of amino acids in the colon, thus limiting the proliferation of probiotics. Thus, the development of protein-derived prebiotic materials capable of reaching the colon for use by colonic microorganisms is a new direction of prebiotic research.
Studies have shown that casein and its polypeptides, lactoferrin and its polypeptides, etc. all significantly promote the growth of bifidobacteria and lactobacilli, and that degradation of milk proteins can produce amino acids such as leucine, cysteine, tryptophan, tyrosine, etc. necessary for the growth of probiotics. The digestibility of protein in stomach and intestine is obviously reduced after the protein is modified by Maillard reaction glycosylation, and most MRPs can not be absorbed by front digestive system but can only be utilized by colon microorganisms in a glycolysis or proteolysis mode, which shows that protein glycosylation is a modification means for effectively improving the stomach and intestine passing rate of protein. However, the Maillard reaction is affected by the concentration of reducing sugar, temperature and time. Meanwhile, fat oxidation or decomposition of milk fat occurs during the heat treatment, and thus the maillard reaction degree may be adversely affected.
