격막 및 무격막 방식의 전해수 처리에 의한 샐러리 및 생굴의 세정처리에 따른 살균 및 저장성 효과를 조사하였다. 샐러리를 대상으로 세정처리에 따른 저장중의 품질변화를 살펴본 결과, 총균수는 전해수 처리구에서 무처리구에 비하여 약 1/200∼1/1,000 수준, 대장균군수는 약 1/100 수준으로 감소하였다. 그리고 수분함량, pH, 경도, 비타민 C 및 잔류염소 함량 등의 변화는 저장 10일째까지 처리구에 관계없이 거의 유사한 경향을 보이거나 차
This study was carried out to investigate the efficacy of electrolyzed water manufactured with or without diaphragm on sterilization and preservation of cut-celery and shelled raw oyster. In cut-celery, total viable cell count and coliform group in the treatment of electrolyzed water were decreased to about 1/200∼1/1,000 level and about 1/100 level comparing non-treated ones. But moisture content, pH, hardness, vitamin C and residual chlorine content were showed a little difference among treatments up to 10 days at 10. L and a color values were gradually increased in all treatments, and color differences(E) were remarkable between treatment and untreatment sample. In overall acceptability, cut-celery treated with electrolyzed water showed somewhat higher score than that of other ones treated with tap water and 100 ppm NaClO solution until 5 days of storage. After 48 hours of storage, it was showed that VBN, total viable cell count and coliform count of shelled raw oyster treated with electrolyzed alkali water produced by non-diaphragm system are lower by about 3 mg%, 1∼2 log cycle and 2 log cycle respectively than that of ones treated with sea water. Total viable cell count of shelled raw oyster just after treatment was lower by about 1 log cycle than that of ones treated with sea water, and any significant increment was not found after 24∼48 hours of storage.
