摘要：

Research was undertaken to develop improved methods of sanitizing apples contaminated with Escherichia coli, Unwaxed Golden Delicious apples, inoculated with nonpathogenic E. coli, were washed with 200 ppm Cl-2, commercial washing formulations, 5% H2O2, or combinations of H2O2 with commercial formulations at ca, 20 degrees C or 50 degrees C, Heated commercial formulations achieved a 2.5 log reduction in E. coli load, compared to a 2 log reduction for 200 ppm Cl-2. However, heated combinations of H2O2 with acidic surfactants achieved a 3-4 log reduction. Residual H2O2 in treated apples dissipated within several hours. These results demonstrate the efficacy of H2O2 in decontaminating apples containing E. coli.
