| 目的 研究自发气调处理对采后软枣猕猴桃果实品质的影响。方法 将软枣猕猴桃置于塑料气调箱内，气调处理组果实放入气调箱封盖处理，对照组进行不封盖处理，于4 ℃下贮藏64 d，每16 d对软枣猕猴桃呼吸代谢及抗性相关指标进行测定，即气调箱内CO2和O2含量，可溶性固形物（TSS）、丙二醛（MDA）、总酚含量，及抗氧化相关酶活性等指标。结果 自发气调处理能够使CO2和O2含量维持在适宜的贮藏范围内，从而保持较高的TSS和总酚含量，抑制MDA含量及多酚氧化酶（PPO）活性，增强过氧化物酶（POD）、苯丙氨酸解氨酶（PAL）和过氧化氢酶（CAT）活性。结论 贮藏48~64 d，自发气调处理软枣猕猴桃的最适宜气体环境为体积分数3%左右的CO2和体积分数16%左右的O2，保持了软枣猕猴桃较好品质的机制，通过诱导果实的苯丙烷及抗氧化代谢实现。 |
| 英文摘要: |
| The paper aims to study the effect of modified atmosphere treatment on the quality of postharvest actinidia arguta fruit. The actinidia arguta was placed in a sealed air conditioning preservation experiment box and an opened air conditioning preservation experiment box (serving as control), and then stored at 4 ℃ for 64 d. The respiratory metabolism and resistance indexes such as the concentration of CO2 and O2 in the box, the contents of total soluble solids (TSS), malondialdehyde (MDA) as well as total phenolic, and antioxidant enzyme activity were analyzed every 16 d. The results showed that modified atmosphere treatment could maintain proper CO2 and O2 concentration to maintain higher TSS and total phenolic contents, inhibit MDA content and polyphenol oxidase (PPO) activity as well as enhance the activities of peroxidase (POD), phenylalanine ammonia lyase (PAL) and catalase (CAT). Therefore, during the storage of 48~64 d, the most suitable gas environment for modified atmosphere treatment of actinidia arguta is about 3% CO2 volume fraction and 16% O2 volume fraction. The mechanism for maintaining the quality of actinidia arguta is based on inducing phenylpropanoid and antioxidant metabolism. |
