| 中文摘要: |
| 为延缓香蕉成熟衰老，维持香蕉品质劣变并延长货架期。采用涂膜法将40 g/L的桃胶液涂于香蕉表面，系统探究桃胶涂膜处理对香蕉保鲜效果的影响。结果表明，与未涂膜相比，桃胶涂膜处理可显著延缓香蕉果皮黄化进程，维持较高的淀粉含量，抑制还原糖、可溶性固形物和可滴定酸的积累，较好地保持果实硬度。此外，桃胶涂膜处理可提高超氧化物歧化酶活性，抑制过氧化物酶活性，降低超氧阴离子自由基的生成速率和相对电导率，减少褐斑产生。综上，桃胶涂膜处理通过调控活性氧代谢和细胞膜完整性，有效延缓香蕉后熟作用，从而维持较好的贮藏品质。本研究为桃胶基天然保鲜材料的开发和应用提供了理论依据。 |
| 英文摘要: |
| Bananas are typical climacteric fruits, prone to mature and aging after harvest, leading to a deterioration in quality and shortening shelf-life. In this study, the preservation effect of bananas coated with 40 g/L peach gum solu?
tion was explored. The results showed that, compared with the uncoated fruits, the peach gum coating treatment effec?
tively delays the yellowing of banana peels, maintains a relatively high level of starch content, inhibits the formation of
reducing sugars, soluble solids, and titratable acids, and better retains the firmness of the fruit. In addition, the peach
gum coating treatment enhanced the activity of superoxide dismutase, inhibited the activity of peroxidase, suppressed
the generation rate of superoxide anion radical and the relative electrical conductivity, decreases the occurrence of
browning spots. In summary, peach gum treatment can effectively delay the post-ripening of bananas through regulat?
ing reactive oxygen species metabolism and cell membrane integrity, thereby maintaining a better storage quality. This
study provides a theoretical basis for developing and applying peach gum-based natural preservation materials. |
