The impact, were studied on the quality of fresh-cut vegetables. The result of comparison, on the vegetable hardness and hardness during the chill by different cleaning dipping solutions was found that the 3% sodium chloride may result in the large loss of water from vegetable also hurts their qualities; hence it is not suitable for the processing of vegetables. In addition, the 3% sodium bicarbonate for cleaning and dipping vegetables caused the downward trend of their textures. The hardness slightly also down comparing the other treatments. The 0.5% IOSP group was indicated effectively improving the hardness of vegetables, and the hardness after storage was still better than the other groups. For poached Chinese cabbage, treated with 0.5%IOSP, could delay the decline in vegetable hardness after cooking and heating, and maintain the better taste. It was shown the significant difference (p <0.05) with the other groups. Regarding to color, treating with different cleaning solutions was found the influence on the L *, a * and b * value of cuted vegetables, by the sensory evaluation showed that these changes would not affect consumers’ degree of preference for the color of vegetables. For green vegetables, all kind of cleaning solutions did not affect significantly the total chlorophyll content. For the microbiological testing, the 0.5% IOSP washed vegetables could reduce 2.55-4.06 log CFU / g of the total count plate number, and 2.7-3.38 log CFU / g of the coliform group number. The function of reducing bacterial numbers was more effectively than other groups. The result of IOSP for the degradation of active pesticide ingredient showed the best ability on the Carbaryl pesticide, with the amount of added 0.5 percent. The residual amount was 1.91ppm, indicating removal percentage is as high as 80.9 percent, but the effect of degradation to Fenthion and Methomyl pesticide was not obviously.
