오존수 처리콩나물의 저장 중 품질변화를 조사하였다. 콩나물 재배 중 오존수 처리는 콩의 수침시와 주수시에 물을 사용한 것(W/W), 수침 시만 오존수를 처리한 것 (O/M), 주수 시에만 오존수를 처리한 것 (W/O), 수침시와 주수시에 각각 처리한 것(O/O)으로 나누어 각각 5일간 재배하였다. 저장은 콩나물을 0.01 mm polyethylene film 에 포장하여 1와 2에서 저장하였다. 저장수명은 오존수 처리와 무처리간의 뚜렷한 차이를

This study was conducted to investigate the changes in quality of soybean sprouts grown by ozone treatment during storage. Soybean spouts were cultivated under conditions of ozone water watering after soaking in water (W/W), watering after soaking in ozone water (O/W), ozone water watering after soaking in water (W/O) and ozone water watering after soaking in ozone water (O/O). The ozone concentration in soaking of soybean and watering of soybean sprouts was 0.3 ppm, respectively. No significant difference in shelf-life between W/W soybean sprouts and ozone treated samples showed. But shelf-life of soybean sprouts stored in 0.01 ㎜ polyethylene film at 10 and 20 prolonged 4 and 2 days, respectively. The slow growth of total microbe in the ozone treated samples stored at 10 was observed, whereas that of products at 20 showed rapid growth during storage. However, no great difference occurred among samples in the changes of moisture, vitamin C and chlorophyll content during storage. Higher hardness of soybean spouts stored at 10 and 20 was kept in the O/W and W/O products. Color, flavor and overall acceptability evaluated by sensory teat during storage had higher scores in O/W products as compared to the other samples.
