Lactoferrin Protein Powder Introduction

Lactoferrin (LF) is an important non heme iron binding glycoprotein in milk, with a molecular weight of 70-80 kDa. It is composed of a single polypeptide chain and 2-4 polysaccharide side chains, and is mainly expressed and secreted by breast epithelial cells. Lactoferrin was first found in animal milk by Sorensen in 1939, and it was first isolated from cow milk by Groves. Because the complex formed by iron binding is red, it is called "red protein". In 1961, Blanc and Isliker formally named this protein obtained from human milk lactoferrin.

Lactoferrin Protein Powder essential information

1. Distribution of lactoferrin

Lactoferrin is widely distributed in mammalian milk and other tissues and their secretions (including tears, bile, synovial fluid and other internal and external secretions and neutrophils). The concentration of lactoferrin in human milk is about 1.0-3.2mg/ml, 10 times that of cow milk (0.02-0.35mg/ml in cow milk), accounting for 20% of the total protein of ordinary human milk. During lactation, the content of lactoferrin changes with the time of lactation, For example, lactoferrin in human colostrum can reach 6-14mg/ml, and it can be reduced to 1mg/ml in normal milk period.

Lactoferrin and its protein degradation product - lactoferrin peptide have a wide range of biological activities, including broad-spectrum antibacterial effect, anti-inflammatory effect, inhibition of tumor cell growth and regulation of immune response of the body. It is considered to be a new antibacterial and anti-cancer drug and a food and cosmetic additive with great development potential. For example, the US Food and Drug Administration has long allowed lactoferrin to be used as a food additive for sports and functional food.

2. Biological function of lactoferrin

In the past decade or more, laboratories around the world have conducted extensive research on the functions of lactoferrin, especially its biological functions. Many new functions are being discovered continuously. Many in vivo and in vitro experiments have proved that lactoferrin really has the functions of anti microorganism, immune regulation, anti infection and tumor growth inhibition.

Antiviral effect of Lactoferrin Protein Powder

① Lactoferrin mainly acts in the early stage of infection or the virus adhesion stage, and prevents the virus from infecting cells by interfering with the contact between virus and cells;

② The natural intact and correctly folded lactoferrin has better virus inhibition effect;

③ The antiviral effect of lactoferrin has nothing to do with its ability to bind iron and other metal ions;

④ The virus inhibition increased with the increase of lactoferrin concentration;

⑤ Lactoferrin has broad-spectrum antiviral properties, and has varying degrees of inhibition effect on various viruses.

Application of Lactoferrin Protein Powder

Lactoferrin appears in animal milk, especially colostrum, providing infants with a variety of biological functions, especially regulating immunity and resistance to pathogenic microorganisms. A large number of studies have proved that lactoferrin, which appears in the eyes, respiratory tract, digestive tract and reproductive tract, provides the first and most important line of defense for mucosal systems that are invaded by a large number of pathogenic microorganisms every day. Therefore, the research, development and application of lactoferrin has become the focus of scientific research.

Lactoferrin is a safe and reliable natural substance extracted from cow milk, and its application in food has been recognized by laws of many countries and regions. With the continuous elucidation of the action mechanism of lactoferrin and the expansion of its development and application scope, lactoferrin has broad application prospects in disease prevention, nutrition supplement, food and drug preservation, cosmetics, etc.
