김치는 절임 발효 식품으로서 염장이 품질에 영향을 미치는 중요한 요인이다. 이러한 영향에 대해 주재료인 배추의 품종 및 재배 방법의 차이를 구명하고자하였다. 배추의 재배방법(노지, 하우스재배) 및 품종(쌈노랭이, 매력, 춘황, 춘광, 고령지 여름, 옥황씨알)에 따른 수확전 요인(생육 특성)과 수확후에 나타나는 절임특성을 조사하고자 구중, 결구지수(크기), 엽수, 엽두께, 삼투몰 농도, 염함량, 탈염률, 경도를 측정하였다. 수확후 생육면에서는 시설
This experiment investigated the characteristics of salted and fresh Chinese cabbages of different cultivars and using various cultivation methods. We measured the numbers of leaves, sizes, thicknesses, moisture contents, and firmness qualities of fresh Chinese cabbage grown in a plastic house, and outdoors. 'The bulb sizes, leaf thicknesses, and moisture contents of leaves were higher after plastic house cultivation than after growth in the field. Plastic house culture increased the growth rate of Chinese cabbage. Firmness and osmolarity showed better values after outdoor cultivation, however. The growth rates and the levels of chemical components were affected by interactions between cultivation methods and cultivars of Chinese cabbage. The salt levels of salted Chinese cabbage were 1.21.7% (w/w) after cabbages cultivated outdoors were preserved, and 0.91.2 % (w/w) after vegetables grown in a plastic house were treated. The quality properties of postharvest Chinese cabbages after salting varied with cultivation method even when the same cultivars of Chinese cabbage were used. The salt contents of salted Chinese cabbage thus varied with different cultivation methods. The results indicate that the properties of Chinese cabbage vary with the culture systems adapted.
