| 摘要: |
| 目的 研究气调包装和微孔膜包装对葡萄贮藏期间品质的影响，为延长葡萄货架期提供依据。 方法 以新鲜葡萄为实验材料，分别采用O2(5%)+CO2(5%)+N2(90%) (气调1)和O2(10%)+CO2(10%)+ N2(80%)（气调2）等2种气体比例（均用体积分数表示）的气调包装，以及PE参尼龙多层共挤材质的微孔保鲜膜（微孔膜）对新鲜葡萄进行包装，在温度为4 ℃的条件下进行贮藏，每隔48 h对葡萄的硬度、pH值、可溶性固形物、可滴定酸、抗坏血酸、色度和质量损失率等变化进行测定，并进行感官评价。结果 在贮藏0～12 d，从整体保鲜效果来看，微孔膜>气调2>气调2>裸放组。结论 葡萄在采后贮运期间，当葡萄的货架期≤12 d时，使用3种包装均有利于延缓其衰老进程，PE参尼龙共挤微孔膜保鲜膜的保鲜效果最好。 |

| Abstract: |
| The work aims to study the effects of modified atmosphere packaging and micro-perforated film on the storage quality of grapes to provide basis for prolonging the shelf life of grapes. The fresh grapes were respectively provided with modified atmosphere packaging with the proportions of O2 (5%)+CO2 (5%)+N2 (90%) (MAP1) and O2 (10%)+CO2 (10%)+N2 (80%) (MAP2), and PE ginseng nylon co-extrusion micro-perforated film (MPF) and stored at 4 ℃. The changes of grape hardness, pH value, soluble solids, titratable acid, ascorbic acid, chroma and weight loss rate were measured every 48 d, and the sensory evaluation was made. During storage of 0-12 days, the experimental results showed that, the preservation effect was as follows: MPF>MAP2>MAP1> reference group. During postharvest storage of grapes, the three kinds of packaging can delay the aging process of grapes when the shelf life of grapes is ≤12 days. PE ginseng nylon co-extrusion micro-perforated film has the best preservation effect. |
