Abstract

A method for preparing functional edible oil rich in phytosterol esters and diglycerides includes steps of: 1) adding a raw material: adding phytosterol, triglyceride and a molecular sieve into a reactor, wherein a ratio of the phytosterol and the triglyceride is 1:2-1:4, a molecular sieve amount is 50 g/L; heating to 50-60° C. and stirring for 30-60 min, for obtaining a pre-mixture; 2) providing non-aqueous enzymatic transesterification: adding 5-20 g/L lipase into the pre-mixture, adding 100-200 ppm antioxidant, stirring and reacting for 8-12 h with a temperature of 50-60° C. and an atmospheric pressure, stopping heating and naturally cooling to a room temperature; and 3) post-treating: after reaction, removing the lipase and the molecular sieve by centrifugation, for obtaining the functional edible oil. The functional edible oil rich in two nutritional active components is obtained by the one-step method. Products of the present invention do not need separation and purification, and operation is simple.
