He applied for 11 invention patents; published 8 books and more than 100 papers. Some of his research results have reached the international advanced level, and for the first time at home and abroad, the production of asymmetric disulfide ethers such as Bunte salt with important spices methyl 2 a methyl a 3 a furanyl disulfide, and so on, was awarded a Chinese invention patent; for the first time at home and abroad, the use of DMSO to oxidize sulfide ethers such as 2 a methyl a 3 furanyl mercaptan and other sulfide ethers, synthesized bis(2 a methyl a 3 a furanyl) disulfide and other important spices, and was awarded two It is the first time in China to adopt osteopontin, meat and yeast as raw materials to prepare flavor essence by enzymatic digestion and thermal reaction. The above research results have filled more than 20 domestic gaps.
