Abstract
The present invention discloses an enzymatic synthesis method of 1-palmitic acid-2-oleic acid-3-triglyceride stearate, belonging to the technical field of structured lipid processing. In the present invention, a crude product rich in 1-palmitic acid-2-oleic acid-3-triglyceride stearate is obtained by reacting for 2-10 h at 20-70° C. with 1-palmitic acid-2-diglyceride oleate as an acyl acceptor, stearic acid or a derivative thereof as an acyl donor and a lipase as a catalyst, wherein the reaction system is an inorganic or organic solvent reaction system. The present invention provides a highly efficient enzymatic synthesis method of POS, thereby resolving the disadvantage of low POS content and limited use provided by the current synthesizing product of structured lipid. The technology adopted by the present invention certainly has an application prospect in the process of preparing cocoa butter equivalents.
