Fresh gingers, harvested in Seosan, Choongcheongnam-do, were pre-treated by a washing-pasteurizing-drying process, a curing process, and non-treated, respectively. Then they were stored in a lab-scale storage room(12, >92%RH) to investigate the effect of pre-treatment methods on the quality changes during long-term storage. Weight loss of ginger during storage showed ranges in 0.7∼4.3%, and the weight of gingers pre-treated by washing-drying process showed a tendency to change less than those treated by curing. After storage of 130 days, spoilage rates were about 20% in non-treated, 11% in curing treated, and 12% in washing-drying treated ginger,, showing the effect of pre-treatment. The final rate of sprouting was 13∼15% regardless of treatment methods. The firmness of gingers showed a tendency to decrease in stored ginger for the longer period; however, the values were ranged from 1,200 to 1,400 g/, that is hard enough to show a marketable quality. The contents of reducing sugar showed a tendency to increase with the lapse of storage time.

생강의 적정 저장 온ㆍ습도 조건을 구명하기 위하여 7, 12, 2의 온도와 75%, 85%, 95%의 상대습도에서 각각 저장하면서 생강의 품질을 비교 분석하였다. 7와 2에서 습도조건별로 저장한 생강에서는 각각 저온장해 현상과 발아현상으로 인하여 품질저하가 빠르게 진행되었으며, 이들 온도구에서는 습도의 영향은 비교적 크지 않았다. 7에서는 저장 30일부터 곰팡이 발생, 위조현상 등 저온장해가 발생하기 시작하여 90일경 상품성을 소실한 반면 2에서
