When buying milk powder, treasure moms will check the raw materials in milk powder and know that lactoferrin is one of the main components of milk powder. However, people don't know much about lactoferrin in milk powder and its benefits. What are the benefits of lactoferrin?

What are the benefits of lactoferrin? 1, antibacterial

Lactoferrin can effectively help bacteriostasis mainly because lactoferrin can be highly combined with iron in the body, blocking the supply of iron necessary for bacterial survival. In addition, related studies show that lactoferrin can interfere with proton transfer on cell membrane, thus killing microorganisms completely. For example, people with oral ulcers may wish to try to apply lactoferrin to the affected area to help relieve symptoms.

2. Anti-oxidation

Lactoferrin has antioxidant function, and lactoferrin can effectively inhibit the production of malondialdehyde and other substances produced by iron-induced lipid peroxidation. It is the formation of malondialdehyde and thiobarbituric acid that can produce free radicals that oxidize human cells. Lactoferrin supplementation can effectively reduce the production of free radicals and prevent oxidation.

3. Antiviral agents

Lactoferrin has antiviral effect. Researchers from the National Cancer Center Institute of Japan have already obtained experimental results, and it has been confirmed in 1998 that lactoferrin can reduce the damage of virus to human hepatocytes by inhibiting the virus from entering cells. In addition, lactoferrin can also prevent virus particles from entering the target cells and protect the body from virus attacks.

Step 4 fight cancer

The anti-cancer effect of lactoferrin is because lactoferrin can not only supplement human iron deficiency, but also prevent it from being deposited in the body due to excessive iron in the body. Too much iron in the body is easy to cause physical burden and cause a series of diseases. But also can effectively treat diseases caused by iron overload.

5. Promote infant development

Lactoferrin is of great significance for non-breastfed infants to improve their immunity. Lactoferrin can effectively help infants resist the invasion of bacteria and viruses, and help prevent infant diseases caused by viruses. We say that children who grow up with breast milk have much better resistance because breast milk is rich in lactoferrin.

6. Promote the absorption of iron

Lactoferrin can help improve iron utilization and absorption in the body. In particular, lactoferrin, when combined with iron, can help stabilize favorable iron ions, on the one hand, it can reduce the stimulation of iron ions on the gastrointestinal tract, on the other hand, it can also promote the absorption of iron ions in the gastrointestinal tract.

7. Improve the immunity of pregnant women

Pregnant women have a special body and need more immune proteins to help strengthen their body's resistance. In particular, lactoferrin can also help prevent and treat bacterial and viral infections during pregnancy and lactation. In addition, because pregnant women are prone to iron deficiency anemia, lactoferrin can promote the absorption of iron and prevent maternal anemia.

8. Synergy with drugs

Lactoferrin can be combined with drugs, especially with antibiotics and antiviral drugs, which can reduce the dosage of drugs and also play an antiviral role. This can effectively reduce the damage of drugs to human liver and kidney.

9, inhibit cholesterol accumulation

Lactoferrin can participate in the lipid metabolism of human body, inhibit the accumulation of cholesterol in human body and cause high cholesterol and even other physical diseases. In addition, lactoferrin can also prevent platelet aggregation from forming thrombus and blocking blood vessels.

The role of lactoferrin in milk powder in infant feeding compared with formula milk powder, breast-fed infants can make more effective use of nutrients in breast milk, are less prone to various infectious diseases, and can maintain normal growth and development, mainly because breast milk contains lactoferrin, immunoglobulin, lysozyme and other active proteins, which can promote the digestion and absorption of nutrients and protect the body from microbial infection. Among them, lactoferrin also plays an important role in immune and epidemic prevention system by promoting the normal development of gastrointestinal tract, especially mucosal immune system. Adding lactoferrin to milk powder is closer to breast milk, so strengthening these immune factors can increase its immune function.

Newborns' immune system is mature around 1 year, so their anti-infection ability is weaker than that of older children and adults, and they are prone to intestinal diseases, which will affect their nutritional intake and thus their growth and development level. Lactoferrin is a rich natural component in breast milk, accounting for about 20% of the total protein of human milk, and its nutritional value has at least two aspects: one is as a dietary protein source of amino acids; Second, it is beneficial to the biological utilization of iron. However, not all infant formula milk powder contains lactoferrin. Therefore, strengthening lactoferrin in infant formula milk powder to make the nutritional components close to breast milk is extremely important for the nutritional needs and growth of newborn babies, which can promote the growth of beneficial bacteria in the intestine, help infants resist Escherichia coli, reduce common diseases such as diarrhea and enteritis caused by viruses and other microorganisms, and build the first line of defense in life. Studies have shown that oral lactoferrin is safe and reliable without any side effects. Therefore, the effective and reasonable application of lactoferrin in ordinary infant formula milk powder can not only meet the needs of infant growth and development, but also protect the health of infants, which is particularly important for the nutritional needs of non-breastfed infants.

Lactoferrin is a core nutritional protein extracted from milk. (every 14kg milk extract 1g lactoferrin). Lactoferrin is an important non-heme iron-binding glycoprotein in milk. Aiyile added lactoferrin to infant formula, which is very helpful to improve the baby's resistance. The function of lactoferrin: antibacterial and antiviral, regulating immune function, antioxidation, promoting the growth of intestinal probiotics and regulating iron transport.

LF- lactoferrin is a kind of protein related to iron transport and storage, which has important functions such as regulating immune function.

The content of LF- lactoferrin in human milk is the highest, and the content in mature milk is obviously reduced.

The content of LF in breast milk in China is obviously lower than that in foreign countries.

1938 was first found in milk, and its crystal was red. 1960 was isolated from human milk for the first time.

LF- lactoferrin is helpful to transport and promote the absorption of iron ions.

The conformational changes of LF- lactoferrin combined with Fe3+ make the molecular structure of LF more compact, not easy to denature and hydrolyze, and improve the solubility of iron ions.

LF- lactoferrin binds to the surface-specific LF receptor of small intestinal mucosal cells, increasing the iron absorption rate! .

LF can regulate many kinds of immune cells!

LF can regulate both innate immunity and reactive immunity!
