摘要
针对磨盘柿的易软化、易褐变等问题,采取1-甲基环丙烯(1-methylcyclopropene,1-MCP)结合聚氯乙烯(polyvinyl chloride,PVC)保鲜膜的综合处理技术,利用柿果的自发气调作用,研究在低温贮藏环境中磨盘柿品质的变化.结果表明,1-MCP处理能够有效抑制柿果硬度的下降、褐变程度的加深、果实丙二醛(malondialdehyde,MDA)的升高,促进果实中可溶性单宁向不溶性单宁的转化,与对照试验组相比,试验组的果实汁液保持较好,外观完整、色泽明亮,能够最大限度地保持其贮藏品质.
Aiming at the problems of easy softening and browning of Mopan persimmon,the quality change of Mopan persimmon in low temperature storage environment was studied by using 1-methylcyclopropene(1-MCP)combined with polyvinyl chloride(PVC)fresh-keeping film.The results showed that 1-MCP treatment could effectively inhibit the decline of firmness,the deepening of browning and the increase of malondialdehyde(MDA)in persimmon fruits,and promote the transformation of soluble tannins to insoluble tannins.Compared with the control group,the fruit juice of the experimental group maintained better,with complete appearance and bright color,and its storage quality could be maintained to the maximum extent.
