Abstract：In order to meet the demand for road-railway transportation of fresh agricultural products and promote the development of cold chain logistics industry in China, the practical applied results of self-developed thermal storage container were evaluated. In this paper, the temperature data was collected at front, middle and rear parts of thermal storage container by temperature recorder. The quality of two kinds of vegetables (rape, hotbed chives) before and after transportation were analyzed by color difference of L*, a*, b*, hardness, p H and total soluble solids. The results showed that the temperature of container fluctuated with ambient temperature, but its fluctuation was smaller; the temperature of the box is rear ≥ middle ≥ front part. The color difference of L*, a*, b*, hardness and p H of rape had no significant difference in different treatments. Total soluble solids of rape in polystyrene box group, polystyrene box + ice group decreased slightly, and the basket package group increased significantly. Compared with before transportation, hotbed chives of polystyrene box group, polystyrene box + ice group were redder and bluer, with a slight change in color, and there was no significant change in the basket package group. Total soluble solids and p H of hotbed chives in different treatments did not change significantly. Overall, the quality of vegetables in the polystyrene box group, polystyrene box + ice group is better than that of the basket group. The research provides a basis for the optimum design of thermal storage containers.
