摘要
研究了采后草菇的品质劣变与膜脂过氧化作用的关系。结果表明采后草菇在３种不同的贮藏温度下，鲜重损失率、变形度及电解质渗透率明显增加。在丙二醛发生累积的同时，草菇体内ＳＯＤ活性及ＧＳＨ含量下降，相关性分析结果表明，丙二醛含量的增加与鲜重损失率，变形度及电解质渗透率的上升呈显著或极显著正相关，与ＳＯＤ活性及ＧＳＨ含量的下降呈显著或极显著负相关，证明膜脂过氧化作用可能是采后草菇贮藏期间品质劣变的重要原因。
Experiments were conducted to study the relationship between membrane lipid peroxidation and deteriorative changes in postharvest straw mushroom. The results showed that fresh weight loss, deformability and permeability increased during the storage at the three different temperature. With accumulation of MDA, SOD activity and GSH content decreased. The increase of MDA content was positively correlated to the increase of fresh weight loss, whereas deformability and permeablitlity, were negatively correlated to the decrease of SOD activity and GSH content. It was suggested that membrane lipid peroxidation might be the major cause of the deteriorative change in postharvest straw mushroom during storage.
