| 中文摘要: |
| 目的 研究双向拉伸聚丙烯（BOPP）和聚乙烯（PE）等2种不同薄膜包装材料对葡萄低温贮藏期间理化指标的影响，以期为延长葡萄保鲜期提供依据。方法 以‘紫秋’葡萄为实验材料，采用厚度为0.03 mm的BOPP和PE薄膜袋进行单穗包装，在(0±0.5)℃冷库中贮藏，以不包装为对照，每隔10 d测定其生理生化指标，对不同包装材料的低温贮藏保鲜效果进行探讨。结果 采用BOPP和PE包装处理可以减少果实的质量损失和落粒的发生，并降低果梗的褐变程度和维生素C的氧化速度，在贮藏前30 d可以延缓果实可溶性固形物和可滴定酸的降解，相较于PE包装，BOPP包装能更大程度地降低果实腐烂、脱粒的发生，减少质量损失，延缓TSS、TA、花色苷和维生素C含量的下降。结论 BOPP包装贮藏保鲜效果最好，能更好地保持‘紫秋’葡萄果实的外观和内在营养品质，减缓其衰老进程，延长其贮藏期。 |

| The work aims to study the effect of biaxially oriented polypropylene plain (BOPP) film and polyethylene (PE) film on storage physicochemical indexes of grapes during cold storage, in order to provide a basis for prolonging the shelf life of grapes. As the experimental materials, the Ziqiu Vitis Daviaii grapes were packaged in 0.03 mm thick BOPP and PE films, respectively, each with a bunch of grapes, and stored in (0±0.5)℃ cold storage, with no packaging as the control. The preservation effects of different packaging materials at low storage temperature were studied by measuring the physiological and biochemical indexes every 10 days. The experimental results showed that, BOPP and PE packaging films could significantly reduce grape fruit dropping and weight loss, and slow down the rate of stem browning and the oxidation of vitamin C. The degradation of fruit's soluble solid and titratable acids could be delayed 30 days before storage. Compared with PE packaging, BOPP packaging could significantly reduce the occurrence of fruit decay and dropping, reduce the weight loss, and delay the decline of TSS and TA, anthocyanins and vitamin C content. BOPP packaging film has the best preservation effect, which can better maintain the appearance and nutrition quality of ZiqiuVitis Daviaii grape fruits, delay the senescence process, and extend their storage period. |
