英文摘要:

      Milk fat exists in the form of fat globules, and the milk fat globule membrane is a three-layer biological membrane that encases the milk fat globules, with high nutritional value. With the advancement of food science research and separation technologies, the active components within the milk fat globule membrane and their functional roles are gradually being unveiled. The milk fat globule membrane is a complex mixture containing proteins, phospholipids, sphingolipids, gangliosides, choline, sialic acid, and cholesterol, which are essential food constituents with important functions, suitable for application in the production of formulated foods. This article reviewed common proteins and lipids found in the milk fat globule membrane and their bioactivities, summarized recent progress in in vivo and clinical research on milk fat globule membrane and its components in improving gut health, enhancing brain development, mitigating obesity and related complications, addressing frailty in the elderly, exhibiting anti-cancer and antioxidant properties, as well as alleviating fatigue, and discussed the potential mechanisms, aiming to provide insights and references for the development of milk fat globule membrane ingredients and their application in formulated foods.
