几种贮藏方式对新疆厚皮甜瓜采后生理及贮藏品质的影响

为研究贮藏方式对新疆厚皮甜瓜采后生理及贮藏品质的影响,以期得出比较理想的贮藏方式.该实验以新疆厚皮甜瓜"金凤凰"为试材,分别进行了冷藏、冷藏结合臭氧间隙处理、024%-6%、C020.2%-4).5%气调3种贮藏方式的比较研究.结果表明,在6℃贮藏条件下,气调贮藏显著抑制了甜瓜的呼吸强度,延缓了果实的衰老,并有效抑制了果肉硬度、可溶性固形物、Vc和还原糖含量的下降,降低了果实的腐烂指数.保持了甜瓜较好的品质和风味;与气调贮藏的甜瓜相比,冷藏结合臭氧间隙处理的甜瓜的生理指标和贮藏品质不如气调贮藏的好,而冷藏的甜瓜的贮藏品质最差.试验同时得出采用冷藏结合臭氧间隙处理模式,效果好于冷藏,但不及气调贮藏的效果,气调贮藏保鲜甜瓜的效果最好.

Effect on post-harvest physiology and storage quality of Sinkiang thick-skinned melon in some storage methods

In order to study the effect of different storage methods on post-harvest physiology and storage quality of Sinkiang thick-skinned melon.Sinkiang thick-skinned melon was preserved in the experiment with three storage methods:cold storage;cold storage with intermittent ozone treatment;controlled atmosphere storage(CA)with 4%-6% O2 and 0.2%-0.5% CO2.The results showed that CA storage restrained respiration rate of melon markedly,postponed senescence process and it also controlled the decline of flesh firmness and content of titratable acidity,total soluble solids,vitamin C and deoxidized sugar effectively.CA storage reduced rotten exponent of melon,kept better quality and flavor.Compare and contrast cold storage with intermittent ozone and cold storage with CA storage,effect of cold storage with intermittent ozone was inapparent and cold storage was the worst.The test also found that the effect of cold storage with intermittent ozone treatment was better than cold storage,and CA storage had remarkable effect compared with cold storage with intermittent ozone treatment.
