摘　　要：该文以“红灯”樱桃为试材,采用不同的被动气调包装对甜樱桃进行处理,以非酶促系统代谢物抗坏血酸、总花青素、总酚、总黄酮和酶促系统关键酶过氧化物酶(peroxidase,POD)、超氧化物歧化酶(superoxide dismutase,SOD)和抗坏血酸过氧化物酶(ascorbate peroxidase,APX)酶活性为指标进行测定,探究被动气调包装对采后甜樱桃活性氧清除系统的影响。结果表明,相较于对照组,不同的被动气调包装均能不同程度抑制抗坏血酸含量的下降,维持总花青素含量的较高水平(P<0.05),促进总酚和总黄酮的生成(P<0.05),抑制POD酶活性下降,维持高水平APX酶活性,诱导SOD酶活性上升,有效延长了甜樱桃果实的贮藏期。总的来说,P2组(40μm聚乙烯包装)能够最有效促进非酶促系统抗氧化物质的生成,诱导酶促系统关键酶活的增强,有利于提高甜樱桃的抗氧化能力,延缓采后甜樱桃衰老进程。The aim of this study was to explore the effect of passive modified atmosphere packaging on the active oxygen scavenging system of postharvest sweet cherry.The sweet cherry was treated with different passive modified atmosphere packaging.The non-enzymatic system metabolites ascorbic acid,total anthocyanins,total phenols,total flavonoids and the key enzymes of the enzymatic system peroxidase,superoxide dismutase and ascorbate peroxidase enzyme activities were measured as indicators.The results showed that,compared with the control group,different passive modified atmosphere packages could inhibit the decrease of ascorbic acid content.And it could also maintain a higher level of total anthocyanin content(P<0.05)and significantly promote the production of total phenols and total flavonoids(P<0.05).Moreover,passive modified atmosphere packages inhibited the decrease of POD enzyme activity and maintained APX enzyme activity at a high level.The increase of SOD enzyme activity was also induced,and the storage period of sweet cherry was effectively extended.In general,the P2 group(40μm polyethylene packaging)could most effectively promote the production of antioxidants in the non-enzymatic system and induce the enhancement of key enzyme activities in the enzymatic system.Besides,P2 group also could improve the antioxidant capacity of sweet cherries and delay the senescence process of postharvest sweet cherries.
