다양한 제조조건에 따른 전기분해수의 물리적 특성 및 미생물의 표면살균 효과, 이에 따른 저장성 등을 조사하였다. 그 결과 격막방식의 강산성 전기분해수는 최소한 저장 30일, 무격막 방식의 전해수는 최소 저장 15일까지는 초기 물리화학적 특성치와 거의 유사한 수준을 보였으며, 저장온도에 따른 차이는 거의 없는 것으로 나타났다. 시험관내에서 전해수의 미생물 사멸효과는 무격막 방식의 EW-3만이 Salmonella typhimurium이 1분 이내에

This study was carried out to investigate the cleaning effect of sesame leaf, the sterilization effect and physicochemical properties, treated with various electrolyzed water. Initial physicochemical properties could be kept more than 1 month in electrolyzed oxidizing water(EW-1) of diaphragm type and 15 days in electrolyzed water(EW-2 and EW-3) of non-diaphragm system, there was no significant difference by storage temperature. 4 kinds of microorganism (initial total counts, CFU/mL) were sterilized within minutes by electrolyzed water. In fresh sesame leaves, total viable cell count and coliform group in the treatment of electolyzed water were decreased to about log scale comparing non-treated ones. Especially Bacillus cereus was not detected until 13th day when treated with EW-l. Decaying ratio of sesame leaf appears on day 6 of storage in the untreated but the treatments of electrolyzed water has no sign until day 10 of storage. Change in color difference() during storage was observed the treatments of electrolyzed low-alkaline water(EW-2) and electrolyzed neutral water(EW-3) were very desirable at the level after day 13 of storage comparative to the untreated Change of Chlorophyll content was biggest decreased to 6.8 on the untreated and decreased least to 8.35 on EW-3 treated group on 13th day from initial value of The overall sensory evaluation appeared most acceptable in the treatments of EW-2 and EW-3.
