Abstract

This research aimed to investigate the quality of conventional salted cabbages. Here, we studied the general characteristics and microbiological aspects of purchased salted cabbage samples from 15 companies. The purchased salted cabbages used a sun-dried salt, but two samples used a mixture of sun-dried salt and processed salt. There were 4 times of washing, 3 steps of washing after automatic washing, and 3 steps of washing after bubble washing as washing methods for the salted cabbages and ground water was used as the washing water. Also, three samples received HACCP certification. The salt contained in the purchased salted cabbages ranged from 0.5% to 2.0%, representing low salted cabbages. The pH of the purchased salted cabbages ranged from 5.32 to 6.47, and hardness ranged from 1,997 g to 3,665 g. Rewashing was necessary before using some salted cabbages due to foreign materials such as insects, soil, etc. Total bacterial counts of the purchased salted cabbages ranged from 3.36 log to 6.06 log and coliform bacteria ranged from below 1 log to 6.05 log, whereas other pathogens were not detected.

시중 절임배추의 품질 특성을 조사하기 위하여 15개 업체의 절임배추를 구입하여 염도 등 일반특성과 미생물학적 분석을 한 결과는 다음과 같았다. 시중 구입된 절임배추는 대부분 천일염을 사용하였으며, 일부 식염 혼합, 해수를 사용하는 업체도 있었다. 세척 방법으로는 지하수 4회 세척, 자동 세척 후 3단 세척, 버블 후 3단 세척 등의 방법을 사용하고 있으며, 세척수로는 지하수를 사용하고 있었다. 15개 업체 중 3개 업체 제품은 HACCP 인증을 받았다. 시중 절임배추의 염도는 0.5%에서 2.0%로서 저염도를 나타났다. pH는 최저 5.32에서 최대 6.47을 나타내었다. 물성은 최저 1,997 g에서 최대 3,665 g을 나타내었다. 일부 제품은 재세척이 필요한 제품도 있었고, 애벌레, 흙 등의 이물이 나오기도 했다. 시중 절임배추의 일반세균은 최저 3.37 log CFU/g에서 최대 6.05 log CFU/g의 분포를 나타내었다. 대장균군은 불검출에서 최대 2.93 log CFU/g로 나타났다. 이 중 대장균, 황색포도상구균, 병원성균 등은 불검출로 나타났다.
