Mango () is a major tropical fruit, but a short postharvest life hampers marketing. The objective of this work is to assess the influence of a novel nanocomposite poly (ethylene--vinyl acetate) (EVA) film and Chitosan (CTS) affect on mango postharvest quality while stored at 20 °C. The results showed that the film coating treatment reduced the decay rate and weight loss of mangoes, maintaining good postharvest quality of mango fruit. The film coating treatment increased the antioxidant capacity of mangoes by inhibiting PPO activity and increasing the activity of antioxidant enzymes. ACS, ACO, and ethylene release were all suppressed, as well as the expression of the ethylene receptors genes , , and thus delaying mango aging. After harvest, the EVA treatment was superior to the CTS treatment in mango preservation.
芒果（）是一种主要的热带水果，但采后寿命较短，这对其销售造成了阻碍。本研究的目的是评估新型纳米复合聚（乙烯-醋酸乙烯酯）（EVA）薄膜和壳聚糖（CTS）对芒果在20℃储存时采后品质的影响。结果表明，涂膜处理降低了芒果的腐烂率和失重率，保持了芒果果实良好的采后品质。涂膜处理通过抑制PPO活性和提高抗氧化酶活性，提高了芒果的抗氧化能力。ACS、ACO和乙烯释放均受到抑制，乙烯受体基因、和的表达也受到抑制，从而延缓了芒果的衰老。采后，EVA处理在芒果保鲜方面优于CTS处理。
