Abstract

Salting conditions on organoleptic properties and rheology of Chinese cabbage were optimized and monitored by four-dimensional response surface methodology. Experimental conditions were decided in the ranges of salt concentration 8∼12%, salting time 5∼25 hr and salting temperature 5∼15$^{\circ}C$. The salted Chinese cabbage with experiment design was measured on organoleptic and physical properties. The organoleptic form of the salted Chinese cabbage showed maximum score in 11.28% of salt concentration, 9.75 hr of salting time and 12.81$^{\circ}C$ of salting temperature. The organoleptic taste was maximized in 11.19% of salt concentration, 11.38 hr of salting time and 13.58$^{\circ}C$ of salting temperature. The organoleptic mouth-feel was maximized in 11.24% of salt concentration, 11.71 hr of salting time and 13.57$^{\circ}C$ of salting temperature. The organoleptic palatability was maximized in 11.52% of salt concentration, 12.86 hr of salting time and 13.07$^{\circ}C$ of salting temperature. In rheological properties of salted Chinese cabbage, hardness and chewiness decreased with the increase of salt concentration.

절임은 배추의 맛을 결정하는 중요한 공정이므로 배추의 소금 절임시 가장 중요한 영향인자인 소금농도, 절임시간 및 절임온도에 따른 관능적 특성 및 물리적 특성 에 대하여 반응표면분석을 실시하였다. 절임배추의 외관에 대한 관능평점은 소금농도 11.28%, 절임시간 9.75 hr 및 절임온도 12.81$^{\circ}C$에서 가장 높았으며, 맛에 대한 관능평점은 소금농도 11.19%, 절임 시간 11.38 hr 및 절임온도 13.58$^{\circ}C$에서 가장 높게 나타났다. 조직감에 대한 관능평점은 소금농도 11.24%, 절임시간 11.71 hr, 절임온도 13.57$^{\circ}C$에서 가장 높게 나타났으며, 전반적인 기호도에서는 소금농도 11.52%, 절임시간 12.86 hr, 절임온도 13.07$^{\circ}C$에서 가장 높은 관능평점을 나타내었다. 물리적 특성으로 견고성과 씹힘성은 소금의 농도가 증가할수록 값이 낮아지는 경향을 보였으며 소금의 농도에 가장 영향을 많이 받고 절임시간, 절임온도의 순으로 영향을 받는 것으로 나타났다.
