초록

산성 전해수를 이용하여 포도(Vitis labrusca L.)의 저장 안정성을 향상 시킬수 있는 방법을 개발하기 위하여, Campbell Early와 Sheridan 포도를 저장고 내부기체를 산성 전해수에 통과시켜 살균시키는 $0^{\circ}C$ 조건에서 저장하면서 환경기체의 살균처리가 포도의 품질특성과 미생물 생육에 미치는 영향을 조사하였다. 저장환경기체의 살균처리는 포도 품종에 따른 차이가 없이 객관적 품질특성인 가용성 고형물, 적정산도, 가용성 탄닌, 안토시아닌, 에탄올 및 아세트 알데하이드 등의 함량 변화와 관능적 품질특성인 color, aroma, texture, juiciness 및 sweetness등에 거의 영향을 미치지 않는 것으로 나타났다. 반면에 저장기체의 살균처리는 포도 품종에 약간 의존적이긴 하지만 곰팡이를 포함하는 미생물의 생육을 억제하는 효과를 보였다. 이러한 결과로 볼 때 산성 전해수에 의한 저장환경기체의 살균처리는 포도의 품질에는 해가 없으면서 부패를 억제시켜 저장 안정성을 향상시킬 수 있는 방법으로 판단된다.

This study was conducted to investigate the effect of storage atmosphere sterilization using acidic electrolyzed water for table grapes (Vitis labrusca L.). ‘Campbell Early’ and ‘Sheridan’ grapes were stored at $0^{\circ}C$ for 12 weeks under the atmosphere that was passed through an acidic electrolyzed water for sterilization. Storage atmosphere sterilization using acidic electrolyzed water did not influence on the changes in soluble solids, titratable acidity, soluble tannins, anthocyanins, ethanol, acetaldehyde and organoleptic quality attributes including color, aroma, texture, juiciness and sweetness of both varieties during storage. Growth of bacteria and fungus in grapes during storage, however, was inhibited by storage atmosphere sterilization. These results suggest that the storage atmosphere sterilization using acidic electrolyzed water can be utilized for improving the storage life of table grapes.
