Abstract

The rate of salt and sugar into pickled cabbages was determined, and physicochemical characteristics, such as sensory, texture, and pH, of vinegar pickled cabbages during storage were examined at different storage temperatures and vinegar concentrations. The rate of salt and sugar penetration was faster in smaller size and on leaves rather than the stem of cabbage. Also, higher salt and sugar concentration and higher storage temperatures led to increase in salt and sugar permeation rate. As a result of sensory test, lower storage temperature is the most suitable, and 6% vinegar concentration was the mostly appropriate. Hardness and cohesiveness were decreased significantly at the initial $1^{st}$ week storage time, but storage temperature did not show any significant effect. Addition of vinegar contents enhanced the hardness, but decreased cohesiveness. The pH was lowered with increasing vinegar content, indicated most significant factor on pickled cabbage. In general, salt and sugar contents rather than storage temperature have greater influence on permeation rate, and especially, addition of vinegar affects the texture of pickled cabbage.

저장 중 배추의 부위, 크기, 저장온도와 절임액의 농도에 따라 배추에 침투하는 염과 당의 침투속도를 알아보고자 하였고 그에 따른 물성변화도 관찰하였다. 그 결과 배추의 크기가 작을수록, 절임액의 농도가 높을수록 배추로 침투하는 염과 당의 속도가 빨랐으며, 배추의 줄기보다 잎에서 비교적 빠른 침투속도를 보였다. 저장온도가 증가함에 따라 배추의 줄기로 침투하는 염과 당의 침투속도는 증가하였지만 잎의 경우 유의적인 차이를 보이지 않았다. 저장기간에 따른 배추 줄기와 잎의 풍미, 맛, 식감, 전반적인 선호도 등의 모든 항목에서 $5^{\circ}C$ 저장온도에서 저장한 배추만이 시간에 따른 기호도의 유의적인 차이를 보이지 않았고, 저장 3주차부터 저장온도가 높아질수록 기호도기 유의적으로 감소하였다. 또한 절임액의 식초함량이 높을수록 줄기와 잎에서의 모든 항목의 기호도가 유의적으로 증가하였으나 잎의 경우 시간이 경과함에 따라 식초 6%에서 더 우수한 기호도를 나타내었다. 경도와 응집성은 모든 저장온도에서 1주차까지 급격히 감소한 이후 큰 변화를 나타내지 않았고, 식초의 농도에 따른 유의적인 차이를 나타내지 않았으나, 식초를 첨가하지 않은 대조군 경우 실험군보다 경도의 감소폭이 더 크고, 응집성의 감소폭이 더 작게 나타났다. pH의 경우 식초가 첨가된 실험군에서 식초의 농도가 높을수록 더 낮은 값을 나타내었다. 따라서 염 절임 배추에서 저장온도보다는 투입하는 염이나 당의 농도가 더 영향을 미쳤으며 첨가하는 식초함량이 조직변화에 많은 영향을 미침을 보여주었다.
