Abstract

Salt composition may affect the quality of Kimchi. We examined the quality of Kimchi prepared using different types of salt (Korean purified salt, Korean solar salt without bittern, Korean solar salt, Chinese purified salt, Chinese solar salt, and Australian solar salt). Kimchi was fermented for 7 days at $20^{\circ}C$. Following fermentation, the pH of Kimchi decreased during storage, but total acidity and salinity values increased. The type of salt used did not affect quality. Total bacterial counts were 4.18-4.37 log CFU/g initially, and increased markedly during fermentation. Lactic acid bacterial counts were 3.42-4.91 log CFU/g initially, but 7.31-7.79 log CFU/g after 7 days of storage. The sensory characteristics of Kimchi during storage did not vary with the type of salt used in fermentation.

식품 조리 및 제조 가공 시 사용되는 소금은 천일염, 정제염 및 수입산염이 대부분이지만, 아직까지 소금 종류에 따른 식품 제조 시 품질특성에 관한 연구는 미비한 실정이다. 이에 국내산 정제염, 국내산 천일염, 수입산염 등 소금의 종류를 달리하여 제조한 김치를 $20^{\circ}C$에서 7일간 발효시키며 품질을 비교, 분석하였다. 이화학적인 특성으로 pH, 산도, 염도를 측정하였고, 미생물학적인 특성으로 총균수와 젖산균수를 분석하였으며, 또한 관능검사를 실시하였다. 실험 결과, 발효가 진행됨에 따라 전반적으로 김치의 pH는 감소하였고, 소금 종류에 따른 처리구간의 유의적인 차이는 없었다. 산도와 염도는 증가하였으며, 특히 염도는 전반적으로 수입산염이 국내산염보다 높은 값을 나타내었다. 미생물의 경우 총균수와 젖산균수가 증가하였으며, 특히 저장 5일후 균수가 급격히 증가하였다. 관능평가 결과, 처리구간 근소한 차이를 보일 뿐 유의적인 차이를 보이지는 않았다.
