摘要：

We investigated means of improving efficacy of hydrogen peroxide washes in reducing Escherichia coli populations on inoculated apples by increasing contact between attached bacteria and the wash solution. Golden Delicious apples were inoculated with E. coli and treated with heated 5% H2O2 with or without agitation, by spraying and simultaneous brushing or abrading calyx and stem areas, or by vacuum infiltration. Samples were homogenized, diluted, and plated to enumerate surviving bacteria. Population reductions were greater when apples were treated with agitation, by targeted spraying with abrasion, by vacuum infiltration with stem removal, and by application of treatments at 80 degreesC. However, discoloration occurred at temperatures above 60 degreesC.
