目的 探究不同厚度、材质的BioSuee膜对库尔勒香梨货架期品质的影响，筛选出适宜香梨货架期包装的BioSuee膜材料，为生产应用提供技术参考。方法 以新疆库尔勒香梨为实验材料，采用BioSuee膜(T1，T2，T3)和PE保鲜膜(CK)进行包装处理，在18~20 ℃货架期条件下，包装后贮藏18 d，通过分析包装袋内气体组分和生理指标的变化情况，研究BioSuee膜对香梨果实货架期品质的影响。 结果 采用BioSuee膜处理均可较好地保持果实货架期品质，T1，T2和T3组之间效果略有差异，T2处理在抑制果皮转黄、果肉软化、腐烂等方面效果显著。采用T2膜包装的香梨在中后期CO2的体积分数为2%~3%，O2的体积分数在10%~12%之间波动。货架期12 d时，T2组果皮转黄指数为0.2281、腐烂指数为0.200、质量损失率为1.076%、相对电导率为25.46%，分别为CK组的53.23%，74.88%，41.46%和58%，并且T2处理可以显著抑制果实硬度、可溶性固形物、可滴定酸、维生素C的下降，综合品质较好。结论 相对于T1和T3处理，T2处理可以较好地保持香梨货架期果实品质。

The work aims to explore the effect of BioSuee films with different thickness and materials on the quality of Korla fragrant pears during shelf life, and BioSuee films suitable for shelf life packaging of fragrant pears are screened out, which provided technical reference for production and application. Xinjiang Korla fragrant pears are encased in BioSuee films (T1,T2,T3) and PE film(CK), and then stored for 18 days under the shelf life condition of 18~20 ℃. The effects of BioSuee films on the quality of fragrant pear fruit during shelf life are studied by analyzing the changes of gas components and physiological indexes in the packaging bags. The shelf-life quality of fruit could be well maintained by BioSuee film treatment, and the effect of T1, T2 and T3 groups are sightly different. T2 treatment has a significant effect on inhibiting pericarp yellowing, pulp softening and rotting. In the middle and late period, the CO2content of T2 group always remains range from 2%~3%, and the O2 fluctuates range from 10%~12%. On the 12th day of shelf life, the yellowing index of the pericarp rotting index mass loss rate,and relative electrical conductivity of T2 group are 0.2281, 0.20, 1.076 and 25.46%, which are 53.23%, 74.88%, 41.46% and 58% of CK group. And the decrease of the hardness, soluble solid content, titratable acidity and Vitamin C are significantly inhibited by T2 treatment and T2 group has good comprehensive quality. Compared with T1 and T3 groups, T2 group can better maintain the fruit quality of fragrant pears during shelf life.
