| 目的 探索不同自发气调袋在低温下对百香果的贮藏效果。方法 将“台农1号”百香果作为实验材料，使用不同自发气调袋对其进行包装处理，贮藏于(8±0.3)℃的环境内30 d，每5 d进行1次生理和营养指标的测定，研究贮藏期间各自发气调袋内百香果的品质变化，以期探寻“台农1号”百香果的最佳贮藏包装条件。结果 随着贮藏时间的延长，PE袋内的CO2浓度逐渐升高，O2浓度逐渐下降，相较于微孔袋，PE袋推迟了贮藏期间果实的呼吸高峰，延缓了可溶性固形物、维生素C、总黄酮和多酚含量的下降，维持了较高的果皮硬度;而不同厚度的PE袋之间，果实品质也不同，贮藏到30 d时，PE30果皮硬度(16.17 g)、可溶性固定物(15.29%)、维生素C(1.71 mg/kg)、总黄酮(2.14 mg/kg)含量均最高。结论 “台农1号”百香果在低温下采用PE30自发气调袋进行包装，其贮藏效果最佳。 |

| Abstract: |
| The work aims to explore the storage effects of different spontaneous modified atmosphere bags on passion fruit at low temperature. The passion fruit of Tainong No. 1 was used as experimental material, packaged with different spontaneous modified atmosphere bags, and stored at (8±0.3)℃ for 30 d. The physiological and nutritional indexes were measured every 5 d to study the quality changes of passion fruit in each spontaneous modified atmosphere bag during storage to explore the optimal storage and packaging conditions of passion fruit Tainong No.1 . With the extension of storage time, the CO2 concentration in the PE bags increased gradually, and the concentration of O2 decreased gradually. Compared with microporous bag, the PE bag delayed the peak of respiration and the decrease in the contents of soluble solids, vitamin C, total flavonoids and polyphenols, and maintained high peel hardness. Due to different thickness of PE bags, the fruit quality was also different. When stored for 30 d, PE30 peel hardness (16.17 g), soluble solids (15.29%), vitamin C (1.71 mg/kg) and total flavonoids (2.14 mg/kg) content were the highest. Relatively, the storage effect of Tainong No. 1 passion fruit is the best when packaged with PE30 spontaneous modified atmosphere bags at low temperature. |
