Abstract

This study was conducted to compare the storability of some sprout vegetables; alfalfa, broccoli, radish, red-cabbage, and red-radish, packed with 50 low density polyethylene (LDPE) film in MA storage. Most of all 5 different sprout vegetable crops maintained the fresh weight higher than 99% until 10 days storage at 2 and $8^{\circ}C$. The carbon dioxide concentration in packages was higher at 8 than at $2^{\circ}C$. It was higher in radish and red-radish sprouts than other crops. As the oxygen concentration showed opposite trends to carbon dioxide, that of radish and red-radish sprouts decreased more than 3% after 3 days in 8 storage. Ethylene concentration in the packages of alfalfa was 0.1 ppm, significantly higher than other four crops with less than 1.0 ppm. Temperature treatment, however, did not influence the ethylene concentration in packages. The radish and red-radish sprouts, with lowest oxygen concentration in package, showed lowest off-flavor compared to the others. The visual quality of these sprouts in packages showed higher at $2^{\circ}C\;than\;at\;8^{\circ}C$ and was maintained the highest in radish sprouts, followed by red-radish, broccoli, red-cabbage, and alfalfa sprouts in that order. In conclusion, as the sprout vegetables have different shelf-life, of which radish was $4{\sim}5$ days longer than that of alfalfa the distributed condition of sprout vegetables should be differently controlled according to kinds of crops.

저장중 5가지 싹채소, (무, 적무, 적양배추, 알팔파, 브로콜리)의 생체중은 $50{\mu}m$ LDPE필름으로 밀폐하여 $2^{\circ}C$$8^{\circ}C$모두 99%이상 유지되었다. 저장중 포장재내 이산화탄소 농도는 $8^{\circ}C$에서 $2^{\circ}C$에서 보다 높았으며 작물별로 무와 적무가 높았다. 산소농도는 이와 정반대로 $2^{\circ}C$에서 높게 유지되었고, 무와 적무가 가장 낮은 농도를 보였는데 특히 $8^{\circ}C$저장 3일째는 3%미만까지 낮아지기도 하였다. 에틸렌 농도도 $2^{\circ}C$에 비해 $8^{\circ}C$에서 다소 높았으며 작물별로는 알팔파가 0.1ppm으로 가장 낮았고 나머지 4 작물은 작물간 농도차이에 유의성 없이 1ppm미만으로 낮았다. 이취는 산소농도가 가장 낮았던 무와 적무에서 오히려 낮은 수준을 보였으며 온도별로 큰 차이가 없었다. 외관상 품질은 역시 $2^{\circ}C$$8^{\circ}C$보다 높게 유지되었으며, 두 온도 모두에서 무가 가장 높게 유지되었고, 다음으로 적무, 브로콜리, 적양배추, 알팔파 순서였다. 이상의 결과에서 싹채소의 작물간 저장성에 차이를 알 수 있었는데 무와 알팔파의 경우 $4{\sim}5$일의 저장기한의 차이를 보였다. 따라서 싹채소 유통에 있어 작물별 관리가 다르게 실시되어야 할 것이라 생각된다.
