The invention discloses a preparation method of grease rich in beta-VLCPUFA, and relates to the technical field of bioengineering and grease processing.The technical scheme is that according to the method for preparing the grease rich in beta-VLCPUFA through an innovative special freezing crystallization technology, when a large amount of grease is crystallized and separated out, granular dry ice is immediately put at a proper speed, and the grease rich in beta-VLCPUFA is obtained; and the heat released severely when a large amount of grease is crystallized is absorbed through rapid evaporation, so that the crystallization process is smoothly carried out. The method has the beneficial effects that dry ice is adopted as a main cooling means in a crystallization heat release stage, heat which is violently released in a crystallization process is absorbed with very high efficiency, and the crystallization process is accurately controlled, so that an ideal crystal state is obtained, and a common pot pasting pheno
