Beschreibung
Zusammenfassung:	The invention discloses a method for reducing prometryn in marine bivalves, which belongs to the technical field of food pesticide residue reduction. According to the invention, degradation is carriedout under combined action of direct oxidization of ozone molecules in ozone water and indirect oxidization of active free radicals. The final concentration of ozone is controlled to be 4.0-4.2 mg/L,Na2CO3 or citric acid is adopted to adjust the pH value of the solution to be 6-7, the solution system is in a constant-temperature water bath environment, the temperature is 23-27 DEG C, cleaning isconducted after treatment is conducted for 20-40 min, and a marine bivalve product with prometryn residues greatly reduced is obtained. The method can safely and efficiently degrade prometryn residuesin marine bivalves, the degradation rate can reach 85% or above to the maximum extent, the structure of the product is prevented from being damaged, the processing cost of the product is reduced, theadditional value of the prod
