Lard oil substitute grease as well as preparation method and application thereof

The invention belongs to the technical field of grease, and discloses lard oil substitute grease as well as a preparation method and application thereof, the lard oil substitute grease is obtained by carrying out enzymatic ester exchange reaction, alkali refining deacidification and fractionation or not fractionation on cottonseed solid grease; the triacylglycerol of the lard substitute grease comprises the following components in percentage by weight: 14 to 22 percent of triunsaturated fatty acid triacylglycerol, 2 to 10 percent of trisaturated fatty acid triacylglycerol, 32 to 48 percent of disaturated monounsaturated fatty acid triacylglycerol and 27 to 44 percent of monosaturated diunsaturated fatty acid triacylglycerol. The fatty acid comprises 38-43% of palmitic acid, 10-12% of oleic acid and 41-46% of linoleic acid; through enzymatic modification of cottonseed solid ester, physical and chemical indexes such as sliding melting point, solid fat content curve and crystal form of the obtained grease are si
