| 摘 要： | 以‘石硖’龙眼为材料，研究了ＳＯ２抑制贮藏期间龙眼果皮酶促褐变的机理。结果表明：ＳＯ２通过降低果皮细胞质的ｐＨ值，抑制多酚氧化酶酶活性，保存游离酚和总酚含量，保护还原型抗坏血酸等作用抑制了龙眼果实贮藏期间的褐变。

| Abstract: | The mechanisms of sulphur dioxide controlling enzymatic browning of longan(Dimocarpus longana Lonn . )pericarp during storage were studied.The results indicated that after sulphur dioxide fumigation the pH of cytoplasm declined,polyphenol oxidase(PPO)activity was inhibited,free and total phenol content increased.Reduced ascorbic acid(AsA)content of pericarp increased too.Primarily by affecting reaction conditions and inhibiting PPO,sulphur dioxide controlled enzymatic browning of longan pericarp. |
