摘　　要：以紫香百香果和黄金百香果为试材,以0.8μL/L 1-甲基环丙烯(1-MCP)、1%壳聚糖、1%茶多酚采用两两复配的方式对百香果进行保鲜处理后测定相关指标。结果显示,3种复合保鲜方法对2个百香果品种均有延长贮藏期的作用。紫香百香果在贮藏15 d时,1%茶多酚+1%壳聚糖复合处理(Z3)的可溶性糖、可溶性蛋白、类黄酮含量和过氧化物酶(peroxidase,POD)活性均显著高于对照组和其他处理组(P<0.05),其值分别为7.14%±0.09%、(2.13±0.009)mg/g、(0.814±0.013)OD_(325)/g和(2.05±0.202)U/g。黄金百香果在贮藏15 d时,1%茶多酚+1%壳聚糖复合处理(H_(3))的Vc、可溶性蛋白、类黄酮含量和POD活性均显著高于对照组和其他处理组(P<0.05),其值分别为(17.80±0.168)mg/100 g、(2.50±0.006)mg/g、(0.875±0.010)OD_(325)/g和(2.20±0.061)U/g。综上,1%茶多酚+1%壳聚糖复合处理对百香果的保鲜效果最为明显。Passion fruit and golden passion fruit were treated with 0.8μL/L 1-methylcyclopropene(1-MCP),1%chitosan and 1%tea polyphenols,and the related indexes were determined.The results showed that the three composite preservation methods could prolong the storage period of passion fruit.On the 15th day of storage,the content of soluble sugar,soluble protein,flavonoid and POD activity in the composite group was significantly higher than that of CK and other treatment groups(P<0.05),and the value was 7.14%±0.09%,(2.13±0.009)mg/g,(0.814±0.013)OD_(325)/g and(2.05±0.202)U/g,respectively.The content of Vc,soluble protein,flavonoid and POD activity in the composite group was significantly higher than that of CK and other treatment groups(P<0.05)on the 15th day of storage,and the value was(17.80±0.168)mg/100 g,(2.50±0.006)mg/g,(0.875±0.010)OD_(325)/g and(2.20±0.061)U/g,respectively.In conclusion,the composite treatment of tea polyphenols and chitosan had the most obvious preservation effect on passion fruit.
