본 연구는 김치와 노화 억제에 미치는 영향을 살펴보기 위하여 AIN-76 마우스 식이에 배추, 갓김치, 갓배추김치를 각동결건조 김치를 5%씩 첨가하여 만든 후 김치식이를 노화촉진쥐인 SAMP8에게 1년간 섭취시키면서 간의 노화관련 특성인 유리기 농도와 항산화효소계의 효소활성 변화를 살펴보았다. 노화촉진쥐 간의 총유리기, OH radical, $H_2O$$_2$그리고 TBARS 모두 가려에 따라 증가되었으며, 간에서 생성된 유리기 농도와 TBARS 농도는 대조군에 비해 김치섭취시 유의적으로 감소되었다(p<0.05). 그러나 생성된 유리기를 제거하기 위한 SOD 활성은 오히려 김치섭취군에서 유의적으로 증가되었으며(P<0.05), catalase와 GSH-px, GSH/GSSG의 비율도 김치섭취군에서 유의적으로 증가하였다(p<0.05). 따라서 김치섭취는 노화에 따라 발생되는 간의 유리기 및 TB-ARS 생성은 억제시키면서, 이를 제거하는 항산화계 효소는 활성화시켜 노화를 억제한 것으로 생각된다. 김치종류 중에서는 배추김치보다 배추갓김치와 갓김치가 유리기 생성 억제 및 항상화 효소 활성을 더욱 증진시킨 것으로 관찰되어 이는 첨가된 갓의 항산화물질 때문인 것으로 생각된다.

In order to develop and propagate the low sodium kimchi for preventing high sodium related diseases, the salinity, pH and acidity of cabbage(Bachu) kimchi sampled from home located in 6 big cities(Pusan, Daegoo, Kyungjoo, Daegoo, Jeonjoo, Daejeon, and Seoul) and commercial 6 manufacturers(A~F) distributed in markets were monitored and analyzed in the current study. Salinity was significantly (p<0.05) higher in homemade($3.03%{\pm}0.60$: 1.79~4.40) kimchi than in commercial($2.38%{\pm}0.60$:1.04~2.87) kimchi. Also, salinity was significantly(p<0.05) higher in Pusan($3.45{\pm}0.60%$) kimchi than in Kyungjoo($3.11{\pm}0.39$), Daegoo($3.19{\pm}0.42$), Jeonjoo($2.98{\pm}0.32$), Daejeon($3.00{\pm}0.38$) and Seoul ($2.52{\pm}0.46%$) kimchi. However, there was no significant difference(p<0.05) of salinity in 6 kinds of commercial kimchi. Related to this result, pH of kimchi from homemade and commercial was $4.40{\pm}0.29$(3.72~6.03) and $5.45{\pm}0.76$ (4.23~6.35), acidity of kimchi from homemade and commercial were $0.99{\pm}0.30%$(0.28~2.17) and $0.45{\pm}023$(0.17~0.93), respectively. Thus, the current study provides evidence that we may need to manufacture the low sodium kimchi because all homemade kimchi, especially Pusan and Daegoo kimchi and commercial brand kimchi contained over 2% salinity.

피부는 외부의 물리적 화학적 자극으로부터 신체를 보호하는 중요한 역할을 하며 노화에 따른 조직의 형태학적인 변화를 쉽게 관찰할 수 있는 기관이다. 동결건조한 배추김치, 갓김치, 부추김치를 식이에 10%씩 첨가하여 hairless mouse에 16주간 섭취시켜 피부조직에 미치는 영향을 살펴보았다. 노화가 진행됨에 따라 표피의 두께는 감소하며 본 실험에서 대조군에 비해 김치섭취군에서 유의적으로 두꺼운 것으로 나타났다. 피부 각질화에 관여하는 cytokeratin은 대조군에 비해 갓, 배추, 부추김치군의 순으로 낮았는데 전자현미경적 소견으로도 대조군에서 각질층은 중간원섬유들이 치밀하게 분포된 매우 두꺼운 각질층이 보인 반면 갓김치, 배추김치, 부추김치군은 얇은 각질층으로 배열되어 있었다. 상피기저막의 type Ⅳ 콜라겐은 갓김치섭취군에서 현저하게 증가되어 갓김치 성분들이 피부의 기저막의 노화를 억제한 것으로 사료된다. 콜라겐 함량은 노화에 따라 감소하며 대조군에서 콜라겐의 합성에 관여하는 fibroblast의 RER 발달은 뚜렷하지 않았으나 갓김치군, 배추김치군에서는 RER의 발달이 현저하여 새로운 콜라겐 생성이 활발히 이루어지는 것으로 나타났다. 이러한 결과로 보아 많은 생리활성물질 및 항산화물질이 함유되어진 김치의 섭취는 피부노화를 방지할 수 있을것으로 기대되며 특히 갓김치의 효과가 우수한 것으로 나타났다.

김치의 숙성도를 평가하기 위한 한 방법으로 김치의 숙성과정 중 자연적으로 유출되는 김치액의 색상 변화를 색차계를 이용해서 측정하고, 또한 이들 결과를 성분분석과 관능적인 평가와 비교 조사하였다. 성분분석과 관능검사 결과는, 16$^{\circ}C$에서 숙성 3일째 김치의 숙성 적기 pH인 4.3에 달하였으며 이때 비타민 C 및 carotenoids 함량도 거의 최고치에 달하고 신맛과 조직감도 적당하였다. 숙성온도 4$^{\circ}C$에서는 숙성 6일후에도 미숙단계에 있었다. 숙성온도 16$^{\circ}C$에서 김치액의 $L^{*}$ 값은 숙성기간 중 뚜렷한 변화를 나타내지 않았다. 반면 $a^{*}$ 값은 숙성 4일까지는 상승하다가 이후 급속히 감소하였으며 $b^{*}$ 값은 숙성 3일까지는 증가하다가 그후 거의 변화가 없었다. 김치액량, pH 및 산도는 김치액의 $L^{*}$ 혹은 $b^{*}$ 값과, carotenoids 함량은 다만 $a^{*}$ 값과 높은 상관관계를 나타냈다. 김치액의 색상으로 김치의 숙성 정도를 평가하기 위해서는 $a^{*}$ 혹은 $b^{*}$ 간을 지표로 삼는 것이 바람직하였다. 즉, $a^{*}$ 값이 담금 초기와 비교해서 동등 혹은 낮은 값을 나타내거나 $b^{*}$ 값이 거의 변화가 없을 때는 과숙기에 이르렀다고 할 수 있었다. 김치의 적숙기를 예측하는 한 방법으로 $a^{*}$ 와 $b^{*}$ 의 비( $a^{*}$ / $b^{*}$ )를 이용할 수 있었다. 즉, $a^{*}$ / $b^{*}$ 의 비값이 1이상 흑은 1에 가까울 때는 미숙기, 0.8 부근 일때는 적숙기, 0.8보다 작아 질수록 적숙기에서 과숙기로 점차 옮아감을 알 수 있었다.

The principal objective of this study was to investigate regional characteristics in the consumption of home-cooked varieties of kimchi and jangajji. Data obtained from the third Korea National Health and Nutrition Examination Survey III(KNHANES Ⅲ), which was conducted in 2005, were utilized in this study. A total of 7,810 data were included in our statistical analyses, which were conducted using SPSS 14.0. The total number of home-cooked kimchi and jangajji were 22 and 11, respectively, and Korean cabbage kimchi, young radish kimchi, and kkakdugi were the top 3 varieties of kimchi. Leaf jangajji, green pepper jangajji, and garlic jangajji were most frequently consumed. Additionally, the results of this study revealed significant correlations between neighboring areas in the ranking of consumption of kimchi varieties, whereas the jangajji varieties did not evidence results as distinct as were noted with kimchi. Different kimchi and jangajji variety consumption patterns were noted between the Middle West and South areas, coastal and inland areas, and cities and provinces. Spicy kimchi varieties, in particular, were enjoyed more frequently by households in the South than those in the Middle West. Further analysis using PROXSCAL multidimensional scaling demonstrated the proximity between areas in terms of kimchi and jangajji consumption patterns. In conclusion, more effort should be extended to encourage the consumption of home-cooked regional foods.

In this study, we have attempted to characterize the effects of encapsulated mustard oil with regard to the extension of the shelf life of kimchi. The quantity of mustard oil or encapsulated mustard oil added to the brined cabbage in this study was 0.05%(w/w). Overall, the fermentation processes in the encapsulated mustard oil-added kimchi (EMO) and mustard oil-added kimchi (MO) occurred at a slower rate than in the controls. The periods during which the MO and EMO kimchi samples were edible were prolonged for more than two weeks, according to measurements of pH, total acidity, and microbial changes. The overall acceptability of EMO was superior to MO throughout the entirety of the fermentation period. Sensory evaluation verified that EMO yielded a more favorable product than the MO and control varieties. Encapsulated mustard oil can be employed as a natural food additive to prolong the shelf life of kimchi, via an induced delay of the fermentation process.

The modernization process of Korea, which can be considered westernization, has influenced Korean folk culture. In this process the kimchi culture could be destroyed. However the kimchi culture has survived very well to date. This study was conducted to investigate the cause of this survival of the kimchi culture. To accomplish this, the enormous influence of modernization on kimchi culture and the cause of its successful survival was investigated in the middle region of the Korean peninsula. We think that the kimchi culture can survive because of the inherent system and structure. Kimchi is composed of vegetables, salt, seasoning, and salted seafood (jeotgal), which are systemized. We also described the kimchi ethnography in this region to study the regional characteristics. The eastern coast uses a different method to salt the cabbage during the production of Kimchi, namely it uses seawater to accomplish this. Additionally, pollak broth is used instead of jeotgal. However nowadays the regional uniqueness of kimchi culture has greatly disappeared in large part, and Korean kimchi is standardized in this region.
