Background
In the process of children growing up, the problem which is concerned by parents is how to improve the immunity of children, and lactoferrin is usually added into the main milk powder in the market as a means for improving the immunity of children. Lactoferrin, also known as "milk transfer protein" or "hemoglobin", is a globulin present in mammalian whey. The biological functions of lactoferrin include participation in iron metabolism, participation in body antibacterial, anti-inflammatory and immune regulation, regulation of gene expression, intervention in cell reproduction, antioxidation, and the like. As a broad-spectrum antimicrobial agent, lactoferrin inhibits both iron-requiring gram-negative bacteria such as escherichia coli and salmonella, and gram-positive bacteria. Lactoferrin has positive effects in promoting infant growth, and preventing and treating common diseases of infants such as diarrhea, neonatal necrotizing enterocolitis, neonatal septicemia, respiratory diseases, etc. In addition, lactoferrin has important significance for promoting the skeletal growth of infants, slowing down the bone loss of women in menopause and improving osteoporosis of old people.
However, the ingredients added in the milk powder can not be absorbed by human bodies, the absorption of corresponding substances can be influenced due to different compatibility of different formula proportions, the absorption rate of each effective ingredient can be directly influenced by the selection of compatible substances, and the formula milk can not achieve the alleged effect due to the absorption rate even if lactoferrin is added in the existing formula milk. Therefore, there is a need to develop a formula which can effectively improve the immunity of children.
