Agaricus bisporus produces substantial ethylene during storage and transportation, which accelerates ripening and senescence, thereby shortening the shelf-life. In this study, a novel food packaging material with ethylene removal property was prepared to increase storage time of Agaricus bisporus. 1-Methylcyclopropen and molecular sieves loaded with potassium permanganate were used as ethylene scavengers to coat the fresh-keeping paper. SEM, FT-IR and DSC analyses proved that these functional components were successfully coated on the fresh-keeping paper. The qualities of the mushrooms packed by prepared functional paper were then determined. The results showed that this prepared functional paper could delay the softening, browning and weight loss of mushrooms during storage by inhibiting ethylene synthesis-related enzymes and gene expression in the mushroom fruiting body, and continuous adsorption and removal of the exogenous ethylene. Consequently, the functional paper could reduce the biochemical and physicochemical quality loss of Agaricus bisporus, thus prolonging its shelf-life.
双孢蘑菇在贮藏运输过程中会产生大量乙烯，加速其成熟衰老，从而缩短货架期。本研究制备了一种具有脱除乙烯功能的新型食品包装材料，以延长双孢蘑菇的贮藏时间。1-甲基环丙烯和负载高锰酸钾的分子筛被用作乙烯清除剂来涂覆保鲜纸。SEM、FT-IR 和 DSC 分析证明这些功能成分已成功涂覆在保鲜纸上。然后确定了用制备的功能纸包装的蘑菇的品质。结果表明，该功能性纸可以通过抑制蘑菇子实体中与乙烯合成相关的酶和基因表达，以及对外源乙烯的持续吸附和去除，延缓贮藏过程中蘑菇的软化、褐变和失重，从而降低双孢蘑菇的生化和理化质量损失，延长其货架期。
