Analysis:
Some people call it protobiotin, bacteriocin or protohealth bacteria, and the broad explanation includes: any application to humans or other animals will help to improve the balance of microorganisms in the intestinal tract of the host. There are many kinds of probiotics, including Lactobacillus (commonly known as bacteria A), Bifidobacterium (commonly known as bacteria B), yeast, Lactobacillus bulgaricus and so on. It can regulate the composition of intestinal colonies, inhibit harmful bacteria and further enhance the epidemic prevention ability of digestive tract.
Probiotics have many functions of regulating physiological functions.
First, promote digestion.
Lactose is transformed into lactic acid through the fermentation of dairy products by probiotics, and protein is hydrolyzed. At the same time, the amount of soluble calcium, phosphorus and some B vitamins increased. In addition, probiotics and their metabolites can promote the secretion of digestive enzymes and intestinal peristalsis, and promote the digestion and absorption of food.
Second, adjust the balance of gastrointestinal flora and correct intestinal dysfunction.
Probiotics can maintain and ensure the best combination and stability of intestinal flora through their own metabolites and interactions with other bacteria. Probiotics can ferment sugar in human body to produce a lot of acetic acid and lactic acid, and also inhibit the growth and reproduction of pathogenic bacteria.
Thirdly, regulating immunity and inhibiting tumor.
Probiotics such as lactic acid bacteria and bifidobacteria and their metabolites can induce interferon production, promote cytokinin, activate immune cells, increase immunoglobulin production, improve immunity and inhibit tumor occurrence.
Fourth, lower serum cholesterol.
Probiotics can reduce the level of cholesterol in blood and prevent coronary atherosclerosis and coronary heart disease caused by hyperlipidemia.
Five, to prevent constipation
Organic acids produced by Bifidobacterium metabolism can promote gastrointestinal peristalsis, and the growth of Bifidobacterium can also increase the humidity of stool, thus preventing constipation.
Probiotics are a kind of intestinal physiological bacteria beneficial to human health. It is a special strain isolated from human intestine. From the perspective of microbial taxonomy, the so-called probiotics are mainly Bifidobacterium, Lactobacillus acidophilus, Lactobacillus casei and so on. Probiotics should have the following characteristics:
1- from human body; 2- Anti-gastric acid and bile; 3- can be attached to human intestinal cells; 4- can be colonized in the intestine; 5- can produce antibacterial substances; 6- Anti-caries bacteria and pathogenic bacteria; 7- Safe for human body; 8- clinically proved to have many health care functions, including: inhibiting intestinal pathogenic bacteria, controlling endotoxemia and diarrhea; Enzymatic hydrolysis of dietary fiber produces short-chain fatty acids, which provide energy for intestinal epithelial cells, produce surfactants and maintain barrier function; Regulating intestinal immune function; Promote growth, control infection and increase the digestion and utilization of nutrients; * * * Intestinal peristalsis to prevent constipation and flatulence; Promote the absorption of calcium, magnesium, iron, zinc and vitamin D; Relieve lactose intolerance; Reduce hypertension; Reduce low density lipoprotein cholesterol in blood; Anti-tumor effect; Improve the tolerance to radiation.
The health care function, functional characteristics and stability of probiotics vary from strain to strain. Only when consumers consume at least 65438+ billion live bacteria every day can they obtain the health care function of probiotics.
The health care characteristics of probiotics depend on the selected strains, and whether the strains can play a health care role is related to the following factors: the number of live bacteria, including the decline of the number of live bacteria during the storage period of raw material powder. Residual rate of live bacteria in processing. Such as punch loss and heat loss. Lost light, etc. Loss of viable bacteria during the shelf life of finished products. The above only involves the stability of the product before it enters the digestive tract. More importantly, after eating, the number of live bacteria is greatly reduced due to the action of gastric acid and bile. In addition, whether it can colonize and survive in the intestine is the key to play the role of probiotics. The stability of these in vitro and in vivo depends on the level of embedding technology. Some manufacturers' products have high stability in vitro and poor stability in vivo. In addition, some products can't release strains in the body, and finally the strains are directly excreted from the body, so they don't have a health care effect. The ideal technology of embedding bacteria is that it has good living bacteria stability in vitro and can tolerate the destruction of gastric acid and bile, but it can release the embedded bacteria well after entering the human small intestine. So that the strain can colonize the intestinal mucosa. DSM's products have the highest cost performance. Probiotic products are more common in hard capsules, tablets or granules.
