| 目的 探究BioSuee可降解膜对鲜食葡萄采后的保鲜作用，以及在贮藏过程中的降解性能，筛选出保鲜及降解效果较好的BioSuee膜材料。方法 以新疆无核白葡萄为实验材料，采用3种不同厚度的BioSuee膜(B4、B5、B6)及PE保鲜膜进行包装，在(15±1)℃条件下贮藏14 d;将膜分别放置在自然条件和土壤中140 d进行观察。通过分析葡萄的生理品质、包装膜内的气体成分和降解情况，探讨BioSuee膜对葡萄贮藏品质的影响，以及其自身的降解情况。结果 采用BioSuee膜处理均可较好地保持果实的采后品质，且具有较好的降解效果，B4膜的降解率为84.7%，B5膜的降解率为81.22%，B6膜的降解率为92.8%。在贮藏结束时，B6膜处理组葡萄果实的质量损失率为7.62%，腐烂率为8.8%，分别为PE贮藏组果实的75.37%和28.33%;无核白葡萄果实的可溶性固形物含量为18.8%，硬度为4.94 N，与PE贮藏组相比分别提高了20.44%和10.46%。在贮藏中后期，B6膜包装中CO2的体积分数为3.5%~4%，O2的体积分数在16.6%~16.7%间波动。在降解结束时，土壤环境中B6膜的质量损失率和断裂伸长率分别为12.64%和6.84%，表面形态和微观结构均出现了明显的破碎和崩裂。结论 与其他处理组相比，采用B6膜能较好地保持无核白葡萄的贮藏品质，且具有较好的降解效果。 |

| The work aims to explore the preservation effects of BioSuee film on postharvest quality of fresh grape and the degradation property of the film during storage, and screen out BioSuee film of good preservation and degradation effects. Thompson seedless grapes of Xinjiang were packed with BioSuee films (B4, B5, B6) and PE film, and stored at (15±1) oC for 14 days. All kinds of films were placed in natural condition and soil for 140 days for observation. By analyzing physiological quality of grapes, gas composition in packaging film and degradation of packaging film, the effects of BioSuee film on grape storage quality and its degradation were discussed. The postharvest quality of grape could be maintained well by all BioSuee films. The degradation rates of B4, B5 and B6 packaging film groups were 84.7%, 81.22% and 92.8%, respectively. At the end of storage, the weight loss rate and decay rate of B6 film group were 7.62% and 8.8%, respectively, which were only 75.37% and 28.33% of PE storage group. The soluble solid content and hardness of the Thompson seedless grape were 18.8% and 4.94 N, which were 20.44% and 10.46% higher than those of PE storage group, respectively. In the middle and late period, the CO2 content (volume fraction) of grade packaged with B6 film remained in the range of 3.5%-4%, and the O2 content (volume fraction) fluctuated in the range of 16.6%-16.7%. At the end of degradation, the weight loss rate and elongation at break of B6 film in soil were 12.64% and 6.84%, respectively. The surface of B6 film was obviously broken and cracked from the observation of morphology and microstructure studies. Compared with other treatment groups, B6 film can better maintain the storage quality of Thompson seedless grape and has more excellent degradation effect. |
