Abstract

The present study was investigated to evaluate on the health improving effect of Kochujang (Fermented Korean hot pepper paste), which was famous as Korean traditional healthy food among foreigners as it was served together with Bibimbap. For comparison, observation was made on the experimental animals (Sprague-Dawley rat) as breeding during 5 weeks, which were divided three groups as into the control groups (N-group) fed with normal feed only and high cholesterol feed only (H-group) and the K-group with combined diet of normal feed and Kochujang extracts (Water soluble complex materials). The most outstanding result was found as the definite fatty liver lesions found from all (100%) of the rats of the H-group at the abdominal opening examination. On the other hand, there was any finding on fatty liver lesions in the N-group as well as the K-group. Therefore, it was more than enough to identify the hypolipidemic effect by visual finding only. Furthermore, from the results of blood plasma analysis from SD-rats fed with Kochujang extract (K-group), more prominent differential findings were found, the value of HDL-cholesterol, which was good for preventing the arteriosclerosis, was more or less higher than that of H-groups. But the level of LDL-cholesterol, which was one of the hazardous agents of hyperlipidemia and arteriosclerosis, was more significantly reduced to the level even lower than that of N-group, based on the statistical analysis, in especial. According to the present results, we could find that the unidentified Korean traditional Kochujang-derived complex components had expressed both the positive health improving effects and hypolipidemic effects on the SD-rat.

오늘날 현대인들의 식생활방식 중 과다한 열량의 영양소 섭취로 인하여 초래되는 비만의 유발 원인 중의 하나로 알려진 고지혈증(hyperlipidemia)에 대한 예방효과가 있는 것으로 알려진 전통방식으로 제조된 고추장의 생리활성 기능성 효과를 분석하고자 하였다. 이 연구에서는 실험동물로서 Sprague-Dawley(SD)-Rat에 대해서 고추장 추출물의 건강증진 효과에 대해서 실험동물을 사용하여 직접 확인하고 시도하였다. 실험군은 실험동물용 일반사료만을 먹인 음성대조군 그룹(N-group)과 일반사료와 고추장 추출물을 동시에 먹인 시험그룹(K-group) 그리고 양성대조군으로 고콜레스테롤 사료만을 먹인 그룹(H-group)으로 구분하여 5주간 사육하면서 건강증진효과의 발현에 대해서 분석하였다. 3그룹의 실험동물을 5주간의 사육 후 해부했을 때 H-group의 모든 동물(100%)에서 공통적으로 심한 지방간(fatty liver) 소견이 관찰되었으나, N-group이나 K-group의 어떠한 동물에서도 지방간 소견은 관찰되지 않았다. 한편, 실험동물의 혈장성분에 대한 혈액생화학적 성적의 비교에서는 고지혈증의 예방에 유익한 성분으로 알려진 HDL의 경우, 고추장 추출물 투여 그룹($25{\pm}8.43mg/d{\ell}$)은 H-group($22.6{\pm}4.16$) 보다 다소간 상승된 수치를 보였으나, 특히 고지혈증을 악화시키는 원인으로 알려진 LDL 경우에는 H-group ($55.8{\pm}44.8mg/d{\ell}$)이 고추장 추출물 투여 그룹($8.6{\pm}1.52mg/d{\ell}$)과 음성대조군인 N-group($9.8{\pm}2.39$)의 성적보다도 유의적으로 높은 수치를 나타냈다. 결과적으로 이 연구에서 SD-Rat에 투여했던 고추장 추출물은 실험동물에서 건강기능 개선효과의 하나인 저지방혈증 효과를 발현한 것으로 사료되었다.
