then cut into 4 pieces of approximately 5 g each. The pieces from all
apples were pooled together and 4 pieces (20 g) were randomly
assigned to each treatment Samples were immersed in the E. coli
inoculum solution under constant agitation for 10 min, followed by
drainage for 1 min and air drying for 30 min. Then, the inoculated
apples were dipped into the aforementioned seven treatment
solutions at a sample/wash water ratio of 1:20 (w/t), and kept
