Abstract: Disclosed is a method for synthesizing a diglyceride. The diglyceride is obtained by mixing a fatty acid donor with glycerol, partial glyceride lipase, and monoglyceride lipase by adding water, then subjecting the same to an esterification reaction, with a reaction time of 8 to 24 hours, and further separating and purifying the same. In the present invention, monoglyceride lipase is used to promote the reaction efficiency of partial glyceride lipase in the esterification reaction, so as to increase the synthesis rate of diglyceride. Compared with a single enzyme, the synthesis time is shortened by half or more, and 45.50% or more of diglyceride is obtained after the esterification reaction. Since substantially no triglyceride is generated in products, the content of DAG reaches 98% or more after the same has been purified by means of molecular distillation.
