  The present invention provides a method for the preparation of diacetyl tartaric acid esters of mono- and di-glycerides, which comprises steps of: adding L-tartaric acid and/or DL-tartaric acid and acetic anhydride into a reaction kettle, adding concentrated phosphoric acid as catalyst and mixing together to form a reaction system; heating the reaction kettle until a temperature of the reaction system reaches 50° C.˜55° C. to initiate a reaction, after the temperature of the reaction system rises and then drops to 80° C.˜90° C., keeping the temperature at 80° C.˜90° C. for 20˜60 min to obtain an intermediate product; adding stearic acid esters of mono- and di-glycerides to the intermediate product, then adding powdery sodium hydroxide as catalyst, controlling an inner pressure of the reaction kettle at −0.09 Mpa˜−0.098 Mpa, heating the reaction kettle again until a temperature of the reaction system reaches 90° C.˜130° C., and keeping the temperature at 90° C.˜130° C. for 20˜40 min to obtain said diacetyl tartaric acid esters of mono- and di-glycerides. The preparation method according to the present invention has advantages of simple process, low production cost, high yield, good product quality and environmental friendliness.
