| 中文摘要: |
| 目的 探究包装材料的阻隔性对樱桃番茄的气调保鲜效果。方法 选择EHA/PE（乙烯乙烯醇共聚物、聚酰胺/聚乙烯复合膜）、PA/PE（聚酰胺/聚乙烯复合膜）、PE（聚乙烯膜）等3种薄膜气调包装樱桃番茄后于（23±2） ℃温度下贮藏，无包装的樱桃番茄在同样条件下作为空白对照。定期检测包装袋内气体组分变化及感官、硬度、可溶性固形物含量、维生素C的变化情况。结果 PE组在整个贮藏过程中CO2体积分数在5%左右，O2的体积分数在6%～16%范围内波动，樱桃番茄处于低O2高CO2环境中，呼吸受到抑制，具有24 d的保鲜期。PA/PE膜、EHA/PE膜包装的樱桃番茄呼吸产生的CO2及空气中的O2无法透过包装膜，包装中O2含量在第3天时便已为0，CO2在第6天时达到30%以上，樱桃番茄处于高浓度CO2中加速了组织腐烂，同时空白组的樱桃番茄呼吸强度和水分流失不受抑制，因此，贮藏期只有18 d。结论 适宜阻隔性的材料气调包装保鲜樱桃番茄，可明显延长其保鲜期。 |

| The work aims to explore the effect of barrier of different packaging materials on the flesh-keeping. Cherry tomatoes were encased in modified atmosphere packaging (MAP) with PA/PE, EHA/PE and PE films and stored at (23±2) ℃, while the tomatoes without packaging were used for comparison under the same conditions. The gas composition in packaging, sugar content, hardness, vitamin C, and sensory quality of Cherry Tomato were regularly measured during storage. The CO2 content of PE group always remained about 5% and O2 fluctuated range from 6% to 16%，in which cherry tomatoes stored at the low O2 and high CO2 atmosphere, postharvest respiration rate was inhibition, so the shelf life of cherry tomatoes could achieve 24 d. The CO2 produced by cherry tomatoes breathe and O2 in the air couldn’t permeate the PA/PE film or EHA/PE film, in which O2 decreased to 0 on the third day and CO2 increase to 30% on the sixth day. The high CO2 caused cherry tomatoes to spoil more rapidly, while its respiratory intensity and water loss were uncontrolled, thus all the shelf life only lasted for 18 d. In conclusion, suitable gas barrier material packing cherry tomatoes will significantly extend the shelf life. |
