This invention belongs to the field of biochemical technology and relates to a method for producing 1,3-diglyceride by immobilizing lipase with imino-modified nanomaterials. The method involves mixing glycerol, fatty acids, and lipase immobilized with imino-modified nanomaterials, and reacting the mixture at 40–80°C for 1–10 hours with stirring to obtain a mixture containing 1,3-diglyceride. The imino-modified nanomaterials synthesized in this invention serve as a carrier for immobilizing lipase to synthesize 1,3-diglyceride.
