摘  要：
利用多变量分析方法探讨4种采后熏蒸处理对李果实品质及抗氧化活性的影响。单因素方差分析的结果表明,二氧化氯显著降低18d贮藏期后李果实腐烂率、总酚、总黄酮、总抗氧化能力以及清除超氧阴离子自由基和DPPH自由基能力,相比而言,1-甲基环丙烯(1-MCP)显著提高李果实花青素、总酚与总黄酮含量,百里酚与乙醇则提高果肉a*值、色度角及色泽比;相关性分析的结果表明,李果实总酚、总黄酮含量与总抗氧化能力、清除超氧阴离子自由基、DPPH自由基和羟自由基能力之间均表现出极显著的相关性效应;偏最小二乘与通径分析表明,腐烂率与果肉a*值呈现正相关性效应,果肉色度角与清除羟自由基能力存在正相关关系。

摘  要：
The influence of four postharvest fumigation treatments on fruit quality and antioxidant properties of ‘Angeleno’plum were analyzed using multivariate analysis.The results of one-way analysis of variance showed that chlorine dioxide significantly reduced fruit decay rate as well as total phenols,total flavonoids,antioxidant ability and scavenging capacities against superoxide and hydroxyl radical after 18 days of storage at 20 ℃.In contrast,1-methylcyclopropene(1-MCP) promoted the total phenol,flavonoid and anthocyanin contents of plum fruit,whereas the pulp a* value,hue angle,and color ratio increased significantly in fruit treated with both thymol and ethanol as compared with the control.The correlation analysis indicated that both total phenol and total flavonoid contents of plum were highly correlated(P<0.01) with antioxidant parameters including total antioxidant activity and scavenging capacities against superoxide,DPPH radical and hydroxyl radical.The results of PLSR and path coefficient analysis showed that decay rate of plums was positively correlated with a* value,whereas hue angle of fruit pulp was positively correlated with hydroxyl radical scavenging capacity.
