Preparation method of medium-and long-chain structured lipid composition for nutritional treatment of breast diseases

The invention provides a preparation method of medium-and long-chain structured lipid composition for nutritional treatment of breast diseases, and relates to the field of lipid synthesis. The preparation method includes the steps that conjugated linoleic acid, medium-chain triglycerides, long-chain triglycerides, conjugated linoleic acid glyceride and phytosterol are used as raw materials, an ester exchange reaction is carried out in a reactor, the pretreatment step is carried out, and medium-and long-chain triglyceride is obtained; after further treatment, the medium-and long-chain triglyceride is mixed with silica, N-acetylneuraminic acid, beta-hydroxy-beta- methylbutyrate calcium, konjac glucomannan, mangosteen extracts, elderberry and yeast beta- glucan, and the medium-and long-chainstructured lipid composition is prepared. The preparation method is simple, convenient and cheap; and meanwhile, the medium-and long-chain structured lipid composition prepared by the preparation method can be used for nutrit
