Global agricultural exports are expected to increase in the future. Sea transportation facilitates the carrying of an incomparably large amount of cargo for a much lower cost than by air freight. However, sea transportation takes much longer and the produce quality is inferior to that transported by air. Accordingly, it is necessary to develop technologies to create a more suitable environment for sea transportation. For this reason, a method was devised in which all fruit and vegetables packaged for domestic distribution are wrapped from the outside of the package as additional packaging with a more versatile film, and an actual export demonstration using this method was conducted in this study. Namely, two sets of 28 different kinds of fruits and vegetables were prepared, one that was wrapped in additional packaging and the other with ordinary packaging. These sets were then exported from Japan's Shimizu Port to Singapore as mixed cargo. Following transportation, instrumental analysis and sensory evaluation were performed to compare the quality of the additionally packaged produce with that of the ordinarily packaged produce. This additional packaging greatly reduced the loss of fresh weight of Chinese cabbage, lettuce, cabbage and Japanese white radish. Moreover, the additional packaging reduced the drying of ‘Shine Muscat’ grape stems. However, some produce such as peaches deteriorated in quality due to slight changes in gas concentration. For many items, additional packaging can be a low-cost option for maintaining quality when exporting fruits and vegetables packaged for routine domestic distribution.

包装巧夺天工，保持新鲜果蔬海运混杂货物品质

预计未来全球农产品出口将增加。海运可以以比空运低得多的成本运输大量货物。但是，海运时间长，产品质量不如空运。因此，有必要开发技术以创造更适合海上运输的环境。出于这个原因，设计了一种方法，其中所有用于国内分销的水果和蔬菜都从包装外部包裹起来，作为附加包装，使用更通用的薄膜，并在本研究中使用这种方法进行了实际出口演示。即准备了两套28种不同的水果和蔬菜，一个用附加包装包裹，另一个用普通包装。然后，这些装置作为混合货物从日本的清水港出口到新加坡。运输后，进行仪器分析和感官评价，以比较外包装产品与普通包装产品的质量。这种额外的包装大大减少了大白菜、生菜、卷心菜和日本白萝卜的鲜重损失。此外，额外的包装减少了“Shine Muscat”葡萄茎的干燥。然而，由于气体浓度的轻微变化，一些产品如桃子的质量下降。对于许多物品，在出口包装用于国内常规分销的水果和蔬菜时，额外包装可能是保持质量的低成本选择。
