Function of lactic acid bacteria 1, lactic acid bacteria can provide nutrition for human body.
Lactic acid bacteria, which can promote the growth of the body, can directly provide the host with available essential amino acids and various vitamins (vitamins B and K, etc. ), it can also improve the biological activity of mineral elements, thus providing necessary nutrients for the host, enhancing the nutritional metabolism of animals and directly promoting their growth.
2. Lactic acid bacteria can improve gastrointestinal tract.
To maintain the balance of intestinal flora, under normal circumstances, the whole digestive tract of animals is parasitic with a large number of microorganisms.
3. Lactic acid bacteria can improve immunity.
On the one hand, Lactobacillus and Bifidobacterium can obviously activate the phagocytosis of macrophages, and on the other hand, they can colonize the intestine, which is equivalent to natural active immunity. It is recognized by the human body that no matter how much it ingests, the human body will not reject foreign proteins, and lactic acid bacteria from plants are more energetic than those from animals, and can reach the human small intestine for colonization in an amount eight times more than that of animals, thus exerting its powerful and stable biological efficacy.
What harm does lactic acid bacteria have? 1. Some active lactic acid bacteria drinks sold in the market virtually make consumers consume a lot of sugar. Eating more sugar may increase dental caries, obesity and obesity. Three highs? The incidence of.
2. At present, there are no reports about possible adverse reactions of lactic acid bacteria. Lactic acid bacteria can not only improve the nutritional value, flavor, preservation and added value of food, but also attract people's attention because of its special physiological activity and nutritional function.
What are the applications of lactic acid bacteria? 1. Making fermented food: Lactic acid bacteria is a kind of probiotics existing in human body, which can be used to make fermented food such as yogurt, cheese, sauerkraut, beer, wine, pickles and pickled products.
2. Contribution to other industries: Lactobacillus microecological preparation provides an efficient, harmless and pollution-free new choice for feed, animal husbandry and aquaculture. With the increasing number of new strains and specific strains used in production, we should fully consider the characteristics of fauna and the relationship between soil and environment, and make scientific and rational use of them in order to obtain the greatest ecological and economic benefits.
What are the physiological functions of lactic acid bacteria? 1. Prevention and treatment of lactose intolerance (symptoms such as abdominal distension and diarrhea when drinking fresh milk) common in some people.
2. Promote the absorption of protein, monosaccharide, calcium, magnesium and other nutrients, and produce a large number of beneficial substances such as vitamin B group.
3. Make beneficial changes in the composition of intestinal flora, improve the function of human gastrointestinal tract, restore the balance of intestinal flora, form an antibacterial biological barrier and maintain human health.
What kinds of lactic acid bacteria 1 are there? Lactic acid bacteria can be roughly divided into two categories. One is animal-derived lactic acid bacteria, because animal-derived lactic acid bacteria are taken from animals. Because the strains are often in a relatively unstable state, their biological effects are also relatively unstable, and it is easy to cause human and animal protein allergy, that is, rejection when eaten in large quantities.
