The application provides a method for improving the flavor and quality of tilapia surimi products, and belongs to the technical field of aquatic product processing, and comprises the following steps: tilapia muscles are cut into small pieces, an improving agent is added, and the muscles are ground; the well-stirred surimi is made into fish cakes and shaped; the fish cakes are taken out after floating, and are placed in cold water for cooling; the shaped fish cakes are respectively fried at 150 DEG C, 180 DEG C and 210 DEG C for 4 min; the fish cakes are vacuum packaged and stored in a refrigerator after cooling; the flavor of the surimi is analyzed, the quality of the surimi is detected, and the deterioration of the surimi is determined and analyzed; threonine, creatinine and glucose are dissolved in a phosphate buffer to obtain A liquid; diethylene glycol is taken, mixed with soybean oil, and mixed with an improving agent by vortexing to obtain B liquid; the A liquid and the B liquid are fully mixed in a 48 mL sealed high-temperature pressure-resistant reaction bottle, and then are placed in an oil bath for reaction and then are placed in an ice water bath for reaction termination; the solution after reaction is removed and is reserved; the MeIQx content, precursor substances and intermediate substances of the MeIQx generation simulation system solution after reaction simulation are determined.

The invention belongs to the technical field of biological medicines, and particularly relates to a substituted coumarin-benzoxazole derivative as well as a preparation method and application thereof. The derivative has a structure shown in a formula (I) or (II), R1 is selected from hydrogen, methyl, chlorine and formyloxyethyl, R2 is selected from hydrogen, methyl, trifluoromethyl and a benzene ring, and n is a positive integer ranging from 2 to 5. The preparation is realized through two-step substitution reaction, raw materials are cheap, the process is simple and convenient, and the method is suitable for industrial production. The derivative has remarkable multi-target activity, can inhibit monoamine oxidase-B and beta-amyloid protein aggregation and butyrylcholine esterase at the same time, has a good antioxidant effect, can effectively improve pathological injuries related to neurodegenerative diseases, and is low in biotoxicity and high in safety. The invention can be used for preparing drugs for treating Alzheimer's disease, Parkinson's disease and other diseases, provides a new efficient candidate molecule for the treatment of related diseases, and has important medical research value and market application prospect.
