Abstract

In order to inhibit rot of soybean sprouts, presoaking treatments of soybeans with various solutions were studied. Optimal soaking time was 20min and citric acid, chitosan, GFSE(Grapefruit seed extract) were more effective. Most of presoaking treatments decreased the rot ratio of soybeans considerably, and didn't decrease germination ratio of them compared to control. Particularly GFSE, chitosan and phosphate buffer were effective. Presoaking treatments besides ethanol showed increased weight and yield of soybean sprouts compared to control, and particularly chitosan treatment increased yield of 67%, weight of 6.9% and length of 9.5% of soybean sprouts compared to control. Presoaking treatments decreased total microbial count of soybeans and rot of soybean sprouts during cultivation.

항균물질을 사용하여 나물콩을 침지처리함으로써 콩나물 부패를 억제할 수 있는 침지조건을 검토하였다. 적정 침지시간은 20분이었으며 citric acid, chitosan 등의 효과가 우수하였다. 대부분의 처리구에서 대조구에 비해 발아율 감소가 일어나지 않은 반면 상당한 부패율 감소가 나타났으며, 특히 GFSE, chitosan, 인산용액의 침지 효과가 켰다. Ethanol 침지처리를 제외한 처리구가 대조구에 비해 중량 및 수율중가의 효과를 나타내었으며, 특히 chitosan 처리구는 대조구에 비해 수율 67%, 개체중량 6.9% 및 전체길이 9.5%의 중가가 나타나 그 효과가 월둥하였다. 침지처리에 의해 나물콩에 부착된 미생물의 수를 감소시킴으로써 재배중 콩나물의 부패를 감소시킬 수 있었다.
