Abstract: At present,milk has become an important part of people's dietary structure.It can not only provide rich nutrition,but also has certain health functions.The function mining and evaluation of milk nutrition is a research hotspot in the field of food nutrition.The function of milk nutrition mainly depends on the active factors,including active protein/polypeptide,active fatty acid,etc.The author reviewed and summarized the literature on the functional evaluation of active factors in milk in recent years,and extracted and summarized several important active proteins from them,mainly including lactoferrin,α-lactalbumin and β-lactoglobulin.The anti-inflammatory,antibacterial,antiviral,anti-tumor and immunomodulatory functions of these three active proteins were systematically explained.At the same time,we also studied several important active fatty acids in milk,including oleic acid,linolenic acid and docosahexaenoic acid,and elaborated their anti-inflammatory,antihypertensive,cardiovascular and cerebrovascular disease related activities and mechanisms.For the specific elaboration of active protein and active fatty acid in milk,the relevant experimental investigation was taken as the breakthrough point,and the mechanism was that the active factors directly or indirectly acted on the target cells and played related functions.

Key words: milk; active protein; active fatty acid; active function
