摘要：Dried tomatoe samples were dipped into 2.5% citric acid solution at 80 ºC for 2 minutes for achieving the intermediate moisture content. Then the samples were coated with natural corn protein zein based films. Different treatments were applied on the intermediate moisture tomatoes to compare the effects of coating process on the quality of tomatoes over 10 months storage at 5 and 20 ºC. Treatments were as follows: (1) control group (not coated), (2) potassium sorbate containing zein film coating, (3) potassium sorbate and ascorbic acid containing zein film coating and (4) (only) zein film coating. Coating was found to be effective on weight loss of samples during storage period. It as also identified that sorbate addition to the films decreased the rate of microbial growth. The effect of storage temperature on total aerobic mesophilic bacteria count was found statistically significant ( P <0.05). However, no significant differences in color values of all samples was observed.
