Hydrocolloid gums are extensively used in food industry. Recently, hydrocolloid gums such as gum arabic have been widely researched as edible coatings to extend postharvest life of fruits and vegetables. Therefore, in this study, the efficacy of gum arabic (GA)‐based edible coating was investigated for maintaining quality of persimmon fruits during ambient storage. Persimmon fruits were coated with 0 and 10% GA and stored at 20 ± 1°C and 80 ± 2% RH for 20 days. The 10% GA‐coated fruits showed significantly lower weight loss, membrane leakage, H₂O₂, and malondialdehyde content than control. GA application suppressed increase in activities of polygalacturonase, pectin methylesterase, and cellulase enzymes. GA‐coated fruits exhibited substantially higher superoxide dismutase, peroxidase, ascorbate peroxidase, and catalase activities. Moreover, coated persimmons showed markedly higher total phenolics, ascorbic acid, antioxidant activity, and titratable acidity, but reduced total carotenoids, total soluble solids, and ripening index throughout the storage.

收获后施用阿拉伯树胶可食用涂层可延缓成熟，并在存储过程中保持柿子的品质

水胶体胶广泛用于食品工业。近来，诸如阿拉伯树胶之类的水胶体胶已被广泛研究为可食用的包衣，以延长水果和蔬菜的收获后寿命。因此，在这项研究中，研究了基于阿拉伯树胶（GA）的可食用包衣在环境存储过程中保持柿果质量的功效。柿子果实涂有0和10％的GA，并在20±1°C和80±2％RH下保存20天。涂有10％GA的水果显示出明显降低的体重减轻，膜泄漏，H ₂ O ₂，和丙二醛含量比对照。GA的应用抑制了聚半乳糖醛酸酶，果胶甲基酯酶和纤维素酶活性的增加。涂有GA的水果表现出明显更高的超氧化物歧化酶，过氧化物酶，抗坏血酸过氧化物酶和过氧化氢酶活性。此外，包被的柿子显示出明显更高的总酚类，抗坏血酸，抗氧化剂活性和可滴定的酸度，但在整个存储过程中总类胡萝卜素，总可溶性固形物和成熟指数降低。
