Description

Active probiotic drink and preparation method thereof
Technical Field
The invention relates to the field of fermentation, in particular to a preparation method of an active probiotic drink.
Background
The probiotics are important beneficial bacteria for regulating intestinal functions and improving the immunity of organisms. The probiotics are various, and mainly comprise probiotics such as bacillus, lactobacillus, bifidobacterium and the like. The lactobacillus can decompose saccharide, protein and fat for direct use by human body, and can synthesize vitamins. Lactic acid, hydrogen peroxide and antibacterial peptide produced by lactobacillus can inhibit harmful bacteria from breeding, improve the level of immune cells of an organism and even prevent cancer. Bifidobacteria are the most important probiotics of the intestinal tract, but are more difficult to culture. The bifidobacterium can produce lactic acid, acetic acid and the like to reduce the pH value of the organism, inhibit the growth of harmful bacteria, stimulate the intestinal tract to wriggle and promote defecation; the antibiotic and bacteriocin produced by bifidobacterium can prevent the growth of pathogenic bacteria. The Bifidobacterium can also synthesize vitamins and promote the utilization rate of phosphorus, iron, calcium, vitamins and proteins. Bifidobacteria produce antibodies and cytokines to enhance immunity and degrade carcinogens. In addition, the bifidobacterium increases superoxide dismutase in blood to remove free radicals in the body and delay senility. The probiotic bacillus can produce spores, is acid, alkali and high temperature resistant, and can smoothly pass through the strong acid environment of gastric juice to reach the intestinal tract for action. The probiotic bacillus can secrete amylase and protease, produce substances such as vitamins, amino acids, short-chain fatty acids and the like, increase the small intestine peristalsis speed and improve the intestinal digestion. The probiotic bacillus can also produce coagulans and lactic acid, kill harmful bacteria, and promote the development of immune organs and the formation of immune cells. The prebiotics are generally oligosaccharides, including fructo-oligosaccharide, galacto-oligosaccharide, isomalto-oligosaccharide, soy oligosaccharides, xylo-oligosaccharide, inulin, etc. The prebiotics can not be digested and absorbed, and does not increase blood sugar and blood lipid. The prebiotics can be used by the probiotic bacteria to produce acid to lower the pH of the intestinal tract and kill harmful bacteria, relieve constipation, and increase the amount of intestinal probiotic bacteria. Prebiotics can improve mineral absorption, promote growth, prevent osteoporosis, and reduce toxic metabolites. In addition, prebiotics can also increase macrophage activity and antibody levels, enhance immunity and resist tumors. The rare sugars mainly include psicose, trehalose, arabinose and the like. The rare sugar can not be digested and absorbed by human body, has almost no calorific value, can not cause hyperglycemia and obesity, is a good substitute of sucrose, but can be absorbed and utilized by intestinal probiotics. The rare sugar can not be used by oral bacteria, and can be used for preventing dental caries. The rare sugar can also promote calcium absorption and prevent osteoporosis. In addition, the rare sugar can inhibit harmful bacteria in intestinal tract, and is beneficial to increase of bifidobacteria in intestinal tract, thereby improving immunity.
In the prior art, the variety of probiotics generally only contains lactobacillus, and the variety is single, so that the function is single, and various probiotics required by a human body cannot be fully supplemented. Many are solid and have no liquid preparation and are effective. Lactose intolerance can be caused by fermentation of multi-purpose dairy products. The fermentation process is long, only the bacterial load is paid attention to, glucose is supplemented for many times in the fermentation process, the blood sugar is increased, the fermentation process is not suitable for people with diabetes and the like, and obesity can be caused. No prebiotics or a single type of prebiotics, result in an inability to meet the probiotic needs in vivo. Generally, the sugar does not contain rare sugar, has higher calorie and also has common taste. Contains few beneficial spores, so that the life cycle of the probiotics is short and the probiotics can not be effective quickly. The fermentation time is long, although the bacteria amount can be increased in the initial stage, the living bacteria consume a large amount of nutrients such as prebiotics due to too high bacteria amount, so that the nutrients are reduced rapidly, and the probiotics after the prebiotics are consumed die rapidly, so that the quality guarantee period of the product is short. The glucose is supplemented for many times in the fermentation process, and the procedure is complex.

The technical scope of the present invention is not limited to the above description, and those skilled in the art can make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and such changes and modifications should fall within the protective scope of the present invention.
