摘要: 为探究5%O2条件下1%~4%体积分数的CO2气体处理对猕猴桃气调贮藏后货架品质的影响,以金桃猕猴桃为试材,设置气调参数分别为5%O2+1%CO2、5%O2+2%CO2、5%O2+3%CO2和5%O2+4%CO2,以普通冷藏为对照,在(1±0.5)℃条件下贮藏210 d后,于常温(25±1)℃下进行腐烂率、冷害指数、失重率、果实硬度、可溶性固形物(Total soluble solid content,TSS)含量、可滴定酸(Titratable acid,TA)含量、乙烯释放速率、过氧化物酶(Peroxidase,POD)活性、过氧化氢酶(Catalase,CAT)活性、超氧阴离子(Superoxide anion,O2·-)含量和过氧化氢(Hydrogen peroxide,H2O2)含量的测定。结果表明,气调处理均能不同程度降低果实腐烂率、冷害指数和乙烯释放速率,抑制失重率、TSS含量上升,延缓果实硬度、TA含量下降,减少H2O2、O2·-累积,保持较高水平CAT、POD活性。其中,5%O2+3%CO2处理效果最好,货架期10 d,果实的硬度和TA含量最高,分别为1.86 kg/cm2和1.18%,TSS含量最低,为14.6%,CAT活性和POD活性最高,分别为30.0 U(/ min·g)和245 U(/ min·g),O2·-含量最低,为2.12 μmol/g,H2O2含量为4.5 μmol/g,且上述指标与对照均差异显著(P<0.05)。综上,建议生产中采用5%O2+3%CO2气调处理进行金桃猕猴桃保鲜,可有效提高果实的货架品质,低温贮藏210 d后,货架期在10 d以上。

Abstract: In order to explore the effects of 1%—4% CO2 treatment at 5% O2 on the shelf quality of kiwifruit after air‑conditioned storage,Jintao kiwifruit was used as test material,and the controlled atmosphere parameters were set as 5%O2+1%CO2,5%O2+2%CO2,5%O2+3%CO2,and 5%O2+4%CO2,respectively.After storage at(1±0. 5)℃ for 210 days,the decay rate,chilling injury index,weight loss ratio,fruit firmness,total soluble solid(TSS)content,titratable acid(TA)content,ethylene release rate,peroxidase(POD)activity,catalase(CAT)activity,superoxide anion(O2·-)content and hydrogen peroxide(H2O2)content were determined at room temperature(25±1)℃.The results showed that different treatments could reduce decay rate,chilling injury index and ethylene production rate,inhibit the increase of weight loss rate and TSS content,delay the decrease of fruit firmness and TA content,reduce the accumulation of H2O2 and O2·-,and maintain the activities of CAT and POD at higher levels.Among them,5%O2+3%CO2 treatment had the best effect. After shelf life of 10 days,the firmness and TA content of fruit were the highest,which were 1.86 kg/cm2 and 1.18%,respectively.TSS content was the lowest(14.6%).CAT and POD activities were the highest,which were 30.0 U(/ min·g)and 245 U(/min·g),respectively.O2·- content was the lowest as 2.12 μmol/g,and H2O2content was 4.5 μmol/g.And the above indexes were significantly different from general refrigerated treatment(P<0.05).Therefore,it is suggested to use 5%O2+3%CO2 treatment to keep Jintao kiwifruit fresh in production,which can effectively improve the shelf quality of fruit. After 210 days of low temperature storage,the shelf life is more than 10 days.
