Lactoferrin (LF), also known as lactotransferrin (LTF), is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk, saliva, tears, and nasal secretions. Lactoferrin is also present in secondary granules of PMN and is secreted by some acinar cells. Lactoferrin can be purified from milk or produced recombinantly. Human colostrum ("first milk") has the highest concentration, followed by human milk, then cow milk (150 mg/L).

Lactoferrin is a metal-binding glycoprotein, each molecule of which binds to two iron atoms and plays an iron transfer role. It is usually used to make lactoferrin powder, which is a special protein product extracted, purified and dried from high-quality fresh milk. It is in powder form, has good fluidity, high iron binding, milk flavor, and no odor such as mold.
There are many products containing lactoferrin on the market, including yogurt, skimmed milk, health food and fermented dairy products. At the end of the 20th century, Japanese dairy products companies began to produce and sell lactoferrin-containing infant formula milk powder. The benefits of adding lactoferrin to infant milk powder include promoting iron absorption and improving intestinal flora. And so on. It has been confirmed in clinical and animal tests that these lactoferrin-containing products are very beneficial to health. It is popular in Japan, South Korea and other countries and regions to add lactoferrin to fermented dairy products, baby food, soy protein products, and meat products to supplement lactoferrin, enhance the body's immunity, and prevent the body from contracting viral colds and intestinal infections. And other diseases.
Function:
Promotes intestinal absorption of iron.
Enhances human immunity and protects the body from interference.
Regulates the balance of intestinal flora and improves human gastrointestinal function.
Lactoferrin is one of the components of the immune system of the body; it has antimicrobial activity (bacteriocide, fungicide) and is part of the innate defense, mainly at mucoses. In particular, lactoferrin provides antibacterial activity to human infants. Lactoferrin interacts with DNA and RNA, polysaccharides and heparin, and shows some of its biological functions in complexes with these ligands.
Food
Lactoferrin is added to infant formula to enhance the immunity and health of infants.
Nutritional health products
Lactoferrin is used to make various immune and iron supplements, suitable for people who need to enhance immunity and supplement iron.
1. Antimicrobial activity
