【摘要】：为了探讨1-甲基环丙烯(1-methylcyclopropene,1-MCP)对芒果经不同物流运输后货架品质及软化酶活性的影响,以"红玉"芒果为试材,经1-MCP处理后进行运输包装,选用航空托运和快递空运两种物流方式从海南运至天津,测定不同处理芒果在常温货架期感官、质地、营养、生理及相关酶活性的变化规律。结果表明,经不同物流运输后的芒果在常温货架(25~28℃)条件下,1 μL/L 1-MCP处理能够较好地保持芒果的货架品质,抑制转黄指数和软化衰老程度的下降,延缓呼吸强度、乙烯释放量及多聚半乳糖醛酸酶(PG)和纤维素酶(CX)活性的上升,维持果实较好的可溶性固形物、可滴定酸及VC含量。不同物流运输处理比较分析得出,航空托运优于快递空运,其中果肉平均硬度、可溶性固形物、VC含量、乙烯释放量及CX活性等指标存在显著性差异。结果说明1-MCP结合航空托运是芒果电商的最佳采后处理方式。

Air consignment and express air transportation were selected to transport mango from Hainan to Tianjin to determine the changes of sensory texture nutrition physiology and related enzyme activity of mango treated at room temperature during shelf life. The results showed that the mango treated with 1 渭 L / L 1-MCP at room temperature (25 ~ 28 鈩，
