摘要：

以‘新疆大籽’石榴为试材，就不同气体成分对其采后果皮褐变机理及果实贮藏效果进行研究。结果表明：8℃下，石榴果实采后的可溶性固形物与可滴定酸含量均呈递减的趋势，且随着贮藏期延长，膜脂过氧化产物丙二醛含量缓慢增加，细胞膜透性逐渐增大；与对照相比，适宜的气调贮藏参数（5%CO2，3%~5% O2）可减缓石榴果皮细胞膜透性的升高以及膜脂质过氧化产物丙二醛的积累，抑制多酚氧化酶活性的增加，并减少酚类物质的氧化，有效地减轻石榴褐变的发生，保持果实品质。

Abstract:

The post-harvest physiology and mechanism of pericarp browning of ‘Xinjiang bigger seeds’ pomegranates under controlled atmosphere storages were studied. The result showed that soluble solids, and titratable acid content of pomegranate fruits decreased gradually during storage. Meanwhile, the MDA content and membrane permeability of pericarp slowly increased. The peel polyphenol oxidase activity showed a declining trend and the content of phenolic substances declined slightly after the early increase with extension of preservation. Compared with the fruit stored at 8℃, the CA treatments significantly alleviated the increase of membrane permeability reduced the accumulation of malondialdehyde (MDA) content, inhibited the polyphenol oxidase activity and decreased the oxidation of phenolic substances of the pomegranate pericarp. The combination of 5% CO2 with 3%-5% O2 was recommended CA storage conditions for ‘Xinjiang bigger seeds’ pomegranate.
