The purpose of this experiment is to study the bactericidal effects of organic acids in a short time on Escherichia coli in order to screen the best organic acid disinfectants for slaughterhouse. Lactic acid, malic acid and citric acid that conform to the standards of food additives were selected, and the sterilization effect of different concentrations of organic acids on Escherichia coli was determined by quantitative sterilization test at different times. At same time, the combined (organic acids and plus surfactants) disinfection effect was compared. The test results show that lactic acid has the best bactericidal effect on E. coli, 3% lactic acid can achieve complete bactericidal effect under 0.5min action time; 0.5% lactic acid combined with 50ppm SDS can achieve complete bactericidal under 0.5min action time. Combined with the resultof 540C acceleration test and the result of organic interference test, combined disinfection was applicated in slaughterhouse. The results showed that the disinfectant had good bactericidal effect and reduced cross-contamination. In brief, the organic acids have good bactericidal effect and have a good market application in the future.
