To accumulate more basic data for the realization of sea transportation of strawberries to Southeast Asia, we conducted an export demonstration test to Singapore under different transportation conditions. Additionally, the effect of closed and semi-closed film packaging of the strawberry packs on quality retention was confirmed in this export test. Using temperature-controlled containers, we maintained a stable temperature during sea transportation, which accounted for most of the transportation period. Conversely, there was a concern regarding the affect of temperature change on the temperature of strawberries owing to the large temperature fluctuation during local transportation, including unloading of the container. Moreover, the humidity in the storeroom during the distribution period was lower than the optimum storage humidity for strawberries, suggesting the need to implement countermeasures against the issue of drying. Most of the shocks during transportation occurred during the domestic and local transportation in Singapore, and shock accelerations of 200ms－2 or higher occurred several times. When strawberries were transported under the 1 and 5℃ settings, neither molds nor rots appeared at 1℃. However, under the 5℃ setting, where the strawberries were mixed with other fresh fruits and vegetables for commercial use, the ambient temperature was stabilized near 7℃, and molds and rots appeared on the surface of the fruit. Through applying MA or perforated packaging to each package of strawberries, the humidity inside the package was maintained at approximately 94-95%, which prevented the damage, loss of fruit firmness, and mass loss during transportation and storage, and maintained marketability for two weeks after the shipment, which is a requisite for sea transportation to Southeast Asia. Under the present transportation conditions, there was no significant difference in the quality maintenance effect between MA and perforated packaging, and the latter was considered to be an effective packaging option when transporting strawberries via sea, considering the risk of gas damage that may occur at high temperatures.
