冷链运输对哈密瓜品质及腐烂率的影响

Effect of Low Temperature Chain Transportation on Qualities and Decay Rate of Hami Melon Fruit

【目的】研究冷链运输对哈密瓜运输品质、腐烂率及和货架期的影响,解决精品哈密瓜运输过程品质劣变,腐烂严重、货架期短的问题。【方法】以哈密瓜(Cucumis meloL ssp.melo Pang)金龙为试材,采用1-甲基环丙烯(1-MCP)处理,冷链运输,研究冷链运输对不同可溶性固形物含量甜瓜果实运输品质、腐烂率、商品率以及货架品期的影响。【结果】冷链运输对甜瓜可溶性固形物含量的变化影响较小,延缓果实硬度的下降。各成熟度甜瓜,采用冷链运输商品率较对照高40%,货架期商品率高30%;冷链运输甜瓜货架期比常温运输延长2d。甜瓜成熟度过高,运输及货架期商品率低,腐烂率高。【结论】冷链运输延缓甜瓜运输过程果实衰老,保持品质,延长货架期,降低腐烂率。

【Objective】 The purpose of this project was to study the effect of the low temperature chain transportation（LTCT） on qualities,decay rate and shelf life in order to resolve its related problems.【Method】Hami melon ＇Jin long＇ was used as the test material to investigate the effect of LTCT on soluble solid content（SSC）,decay rate,marketable rate and shelf life of the melon fruit during transportation.【Result】LTCT had a little effect on the SSC of the melon fruit,but suppress the declining of firmness of the melon.The melon fruit transported by LTCT was 40% higher in marketable rate,30% higher in shelf life than that of the control fruit.The shelf life of the melon transported with LTCT was two days longer than that of the melon transported at normal temperature.【Conclusion】 LTCT could delay the aging of melon fruit,maintain the qualities,lengthen the shelf life,and decline the decay rate of melon fruit.
