In 1991, he won the third prize of scientific and technological progress of China Ministry of Light Industry. As the project leader, the comprehensive utilization project of corn distiller's grains by the provincial science and technology commission filled the domestic gap, reached the international advanced level and applied for the national invention patent. In 1994, it won the third prize of scientific and technological progress in Shandong Province. He presided over the research of α -acetolactate decarboxylase, a key scientific and technological project of the Eighth Five-Year Plan, which filled the gap in China and reached the leading level in China. In 1998, the project won the second prize of scientific and technological progress of Shandong No.1 Light Industry Association. He presided over the research and development of Cordyceps sinensis mycelium cultured by fermentation and its series products, which reached the international advanced level. In 1995, "Zhiling brand Cordyceps sinensis nutrient solution" won the first prize of excellent products of the Ministry of Light Industry and was included in the national torch plan. Its products were exported to the United States and Japan, and the project won the second prize of scientific and technological progress of light industry in China. The research on polysaccharide from Cordyceps sinensis, a key scientific and technological project in the Ninth Five-Year Plan, has passed the appraisal, and its comprehensive technical level is at the international advanced level. In 1998, the project won the second prize for scientific and technological progress in Shandong Province. In 2, the project of enzymatic production of xylooligosaccharides, which is the key scientific and technological project of the ninth five-year plan, passed the appraisal, filling two gaps in China, and its comprehensive technology ranks at the international advanced level. The research on active substances in monascus, the scientific and technological project of China Light Industry Association, has passed the appraisal, and its comprehensive technology is at the leading level in China. In 1998, it won the third prize of scientific and technological progress of Shandong First Light Industry Association. The industrial production of food-grade xylanase, which is the key scientific and technological project of the tenth five-year plan, has passed the appraisal. Endoxylanase produced by Bacillus is the first in China, and the comprehensive technology of the project has reached the international advanced level. Among them, "Research on Food-grade Xylanase Series Products" won the second prize of Shandong Science and Technology Progress in 25. He is in charge of the extended project "Research and Application of Biological Flour Modifier" of the National Tenth Five-Year Plan Scientific and Technological Key Project. In 25, it was appraised by experts that the series of biological flour improvers were the first in China and the technology reached the international advanced level. In 26, the project won the third prize of scientific and technological progress of China Light Industry Federation. In 25, experts identified that the xylo-oligosaccharides produced by the project reached the level of similar products abroad, and the research on enzymatic production of xylo-oligosaccharides from steam exploded wheat straw and co-production of paper was a blank in China, and the technology reached the international advanced level. In 27, it was appraised by experts that the food-grade endoxylanase products produced by the project were the first in China, and the comprehensive technology reached the international advanced level. In 28, the project won the second prize of Scientific and Technological Progress of China National Light Industry Federation. In 28, experts identified that the quality of xylose products produced by this process reached the level of similar products at home and abroad. Its comprehensive technical and economic indicators have reached the international advanced level. In 28, experts appraised that the quality of xylooligosaccharide products reached the level of similar products abroad, and the comprehensive technology of the project reached the international advanced level. In 28, a method for producing xylose by enzymatic method was authorized by the national invention patent. Participated in compiling Functional Fermented Products (China Light Industry Press, 2), Production and Application of Functional Oligosaccharides (China Light Industry Press, 24) and published dozens of papers.
