CA 컨테이너를 활용한 한국산 신선 농산물 품질 유지 효과

초록

This study evaluated the effectiveness of controlled atmosphere (CA) containers in maintaining the quality of fresh horticultural products during long-distance maritime transport. A simulated export experiment was conducted using both reefer and CA containers, focusing on single commodities (oriental melon, Asian pear cv. Wonwhang, and king oyster mushroom) and mixed commodities (paprika, cherry tomato, and summer squash). The impact of packaging types and CA conditions on quality retention was analyzed. The results demonstrated that CA conditions (5/12 and 5/0.04) enhanced storage stability for oriental melon and pear, and CA (1/15) effectively minimized browning and moisture loss in king oyster mushrooms. However, in mixed commodity storage, the effects of CA conditions varied depending on the product. Cherry tomatoes exhibited the best quality retention under CA (5/12), whereas paprika and summer squash suffered peel discoloration and tissue softening under high CO₂ conditions. In the case of products with modified atmosphere (MA) packaging, interactions between the internal gas composition and the CA environment influenced quality changes. Notably, commodities sensitive to high CO₂ levels exhibited physiological disorders under high CO₂ conditions. This study confirms that CA containers effectively preserve the quality of fresh horticultural products and proposes optimal CA conditions for different commodities. In particular, when shipping mixed commodities, it is crucial to continuously monitor the internal gas composition of MA-packaged products in the CA environment, and storage conditions must be optimized accordingly. The findings of this study contribute to the development of quality maintenance technologies for the long-distance distribution of fresh produce.
