The invention relates to functional medium and long chain fatty acid glyceride microcapsules. The functional medium and long chain fatty acid glyceride microcapsules consist of plant blend oil, a wallmaterial, an emulsifying agent, an oil phase antioxidant, an aqueous phase antioxidant, a metal chelator, a heat stabilizer and an anticaking agent. Based on 100 parts of the microcapsules, 30-60 parts of the plant blend oil is added, the plant blend oil comprises the following raw material components in parts by weight: 10-20 parts of linseed oil, 1-3 parts of plukenetia volubilis Linneo oil, 20-30 parts of fructus perillae oil, 1-3 parts of peony seed oil, 1-3 parts of sea buckthorn seed oil, 5-10 parts of cannabis sativa seed oil, 5-20 parts of Chinese wolfberry fruit seed oil, 1-2 parts of acer truncatum seed oil, 10-22 parts of pumpkin seed oil, 3-7 parts of evening primrose oil, 1-5 parts of shea butter, and 16-21 parts of coconut oil. The functional medium and long chain fatty acidglyceride microcapsules have the advantages of having positive effects on reducing blood lipid, improving insulin resistance, protecting endothelial cell functions of cardiovascular disorders, preventing coronary heart diseases, improving protective screen of the immune function of intestines, controlling body weight, and preventing breast cancer, prostatic cancer and carcinoma of colon and rectum.
