Abstract:
【Objective】 In order to explore the effects of different storage methods on quality and active oxygen metabolism of Chinese cabbage, different treatments were used to treat Chinese cabbage in Southern Xinjiang, and the effects of hanging cellars on decay and disease of Chinese cabbage were studied.
【Methods】 Hanging storage mode was adopted for storage, including bundling leaves with root, bundling leaves with root, cutting loose leaves with root and cutting loose leaves.
【Results】 Bundling with root and leaf could delay the decomposition rate, the decrease of VC and the synthesis of crude fiber, improve the activities of POD, SOD and APX, and delay the increase of nitrate content. The content of VC and soluble protein was 0.45 mg/100g and 0.88 mg/g in the root bundling group after 90 days of storage. The activities of POD, SOD, APX and CAT were 12.43 U, 0.83 U, 25.12 U and 1.21 U, respectively, which were 1.35, 1.44, 1.56 and 1.69 times of the control group, respectively.
【Conclusion】 Bundling leaves with root can maintain the postharvest quality of Chinese cabbage, improve the antioxidant capacity of fruit, delay the aging and decay of Chinese cabbage, and prolong the shelf life. This finding provides technical support for the new process of cabbage storage and transportation after harvest.
