Abstract:

【Objective】 Postharvest physiology and storage diseases of Jiashi muskmelon, in relation to the fresh keeping technology were studies. 【Method】 The respiration type and main storage diseases of postharvest Xinjiang Jiashi muskmelon were researched. The effects of storage temperature, pH value, thiabendazole (TBZ) fumigation and chitosan coating on storage quality and black spot disease of Jiashi muskmelon were investigated, while the activity changes of polypenoloxidase (PPO), peroxidase (POD), pectase (PE) and catalase (CAT) of Jiashi muskmelon treated with TBZ and chitosan were measured. 【Result】 Jiashi muskmelon is a climacteric respiratory fruit. Penicillium viridicatum Westling was the main pathogen that led to black spot disease during storage. TBZ fumigation and chitosan coating inhibited the activities of PPO, POD, PE and the growth of pathogen obviously. A TBZ fumigation, pH 5.0 and 5mg&#8226;mL-1 chitosan solution coating of Jiashi muskmelon, and then stored at 0.5-1.5℃ reduced fruit rot, with the decay index being 0.15 and the accepted fruit percentage being 95% after 105 days of storage. 【Conclusion】 The fresh-keeping effect of Jiashi muskmelon was optimum by TBZ and chitosan treatment under suitable pH and temperature during storage.
