Abstract

This study compared quality changes among brined baechu cabbages manufactured by various salting methods and types of salt. Brine, brine and dry salting, and dry salting were used as salting methods. When baechu cabbages were salted by dry salting method, the salinity of brined baechu cabbage increased compared to salting by other methods, even though the quantity of salt used was small. In addition, salinities of leaf and stem were relatively equal among brined baechu cabbages using dry salting method compared to those of other methods. When baechu cabbages were salted using dry method at different salt concentrations (3%, 5%, and 10% of weight of baechu), brined baechu cabbage showed suitable salinity (1.41~1.42%) at 5% salt concentration. Among brined baechu cabbages prepared using dry salting method with different types of salt (purified salt, solar salt, and bamboo salt), bamboo salt produced the highest salinity. Brined baechu cabbages with solar salt and bamboo salt showed significantly lower counts of total aerobic bacteria and higher counts of lactic acid bacteria than others. These results indicate that baechu cabbage can be salted equally, and the amount of salt used can be reduced when baechu cabbage is salted using dry salting method. In addition, using solar salt and bamboo salt can increase the quality of brined baechu cabbage.

본 연구에서는 절임 방법 및 소금의 종류에 따른 절임 배추의 품질특성을 비교, 측정하고 적절한 조건을 찾고자 하였다. 제간수 천일염을 이용하여 염수법, 혼합법, 건염법으로 절임 배추를 제조한 결과 건염법을 이용하여 제조한 절임배추가 줄기와 잎 간의 염도 차가 적고 비교적 균일하게 절여진 것으로 나타났으며, 적은 소금 사용량으로도 높은 염도를 나타내어 절임 시 사용되는 소금의 양을 줄일 수 있을 것으로 생각된다. 건염법으로 소금의 농도와 절임시간을 달리하여 절임 배추를 제조하였을 때 5%의 제간수 천일염을 사용하여 12~15시간 절임을 할 경우 적절한 염도를 나타내었으나, 절임시간이 길어질 경우 배추 조직의 탄력성 저하를 가져와 12시간 이상의 절임은 바람직하지 않은 것으로 나타났다. 건염법으로 정제염, 제간수 천일염, 죽염을 이용하여 절임 배추를 제조하였을 때 죽염을 이용한 절임 배추가 가장 높은 염도를 나타내었으며, 제간수 천일염, 죽염을 이용한 절임 배추에서 유의적으로 총호기성 세균수가 낮고 유산균 수가 높게 나타났다. 따라서 건염법으로 절임 배추를 제조할 경우 절임에 사용되는 소금의 양을 줄일 수 있으며 줄기와 잎 간의 염도 차가 비교적 균일한 좋은 품질의 절임 배추를 얻을 수 있는 것으로 보인다. 또한 배추절임 시 제간수 천일염과 죽염을 이용하면 절임 배추의 품질적인 측면을 향상시킬 수 있을 것으로 기대된다.
