The amounts of thiamin, riboflavin, and niacin in fresh water fishes live in Nak-Dong river were determined and the effects of heating conditions on change in the content of vitamins were also studied with carp meats. The amounts of vitamins were found to be varied a lot among different kinds fishes. The contents of thiamin and niacin in eel were the highest with 460mg% and 10.39mg%, respectively and goby showed the highest content in riboflavin with 3.55mg%. The amounts of riboflavin and niacin in carp were found to be the lowest and the thiamin in goby was the lowest among sample fishes. Vitamin B groups in eel were abundant compare to the others. The concentration of niacin and lipid content in fish were highly related. The linear regressions obtained from the thiamin content and either heating temperature or heating time were Y=-1.45X + 3.54 or Y=-5.51X + 0.02, respectively. The correlation coefficients of those were-0.96 and -0.97 which were statistically significant(p<0.01). Thiamin was readily destroyed by heat and the degree of destruction was much more dependent on the heating time than the heating temperature. When the effects of heating conditions on riboflavin and niacin were studied, destruction of these vitamins were depend only on the heating time, not on heating temperature. The change were statistically significant (p<0.05). It was found that the destruction of thiamin by heat was most serious among three vitamins.

The purpose of this study is reporting the results of first trial for the standardization of children's kimchi in terms of brining standardization, development for the recipe ad pannel test for the children's kimchi. In order to develop the standard recipe for children's kimchi, our research team have visited kimchi factories, temples and houses located in Pusan and Kyung-Sang Nam Do province. Three kinds of chinese cabbage kimchi (hamyang, haeundae, and jinrae kimchi named by region where we collected) which got the top three highest score in panel testing was selected. The original recipes of these kimchi were sightly modified to prepared the kimchi at laboratory. Among three of them, hamyang kimchi which contained dried anchovy power was selected as a model kimchi for development of the children's kimchi recipe. We find out that the optimal salt concentration of brined cabbage and kimchi for the children's kimchi (sliced style kimchi, approximately 2.5X3cm a piece) that showed the hightest pennel score were approximately 1.5% and 2.0%, respectively. The salt concentration of brined cabbage became 1.5, 1.43, and 1.60% after 60 min at 10% brining solution, 45 min at 12% and 30 min at 15%, respectively. The developed recipe used for the children's kimchi at our team is as follows. The major ingredients used for the preparation of kimchi is brined sliced chinese cabbage (salt concentration is 1.5%) 1kg galic 11g, ginger 5.0g, red pepper powder 20.0g, fermented anchovy juice 25.0g, fermented shrimp juice 5.0g dried anchovy and sea weed extracts 30.0g, anchovy power 2.4g glutinious rice gel 40.0g, starch syrup, 10.0g, and apple juice 22.5g. The total acceptability test of developed children's kimchi (test kimchi) was carried out with 84 of 6th grade student during lunch time at elementary school in Pusan where has a school lunch program. Sixty nine percent of student answered test kimchi is very good, 25% of them said it is fair, and only 6% of students answered they didn't like test kimchil. However, for the kimchi supplied from school at lunch, 52% students answered the kimchi is good, 26% of them said it is fair, and 22% of them said they don't like school supplied kimchi. This result tells us that the test kimchi is better than school supplied kimchi and the test kimchi can be developed further as a children's kimchi.

This study is a continuous work for the standardization of children's kimchi preparation. In order to find out the proper red pepper powder for children's kimchi, four kinds of red pepper powder(A, B, C, D) sold in Kyungsang province were used as samples. The proximate composition, color value, capsaicinoids concentration and sugar content in four kinds of the red pepper powder were determined, and sensory evaluation of kimchi prepared with those was carried out for different fermentation times. Moisture contents of red pepper powder A, B, C and D were in the range of 11.59∼13.48%. Lipid and ash contents of samples were in the range of 7.59∼8.39% and 4.34∼7.45%, respectively. In comparision of color values measured by a Hunter colorimeter, red pepper powder A showed the highest value for a and b values. Also A showed the brightest color as measured in ASTA color and L value. Capsaicin concentration of D and dihydrocapsaicin concentration of C were found to be the highest among the samples. The capsaicin equivalent was in the order of D>C>A>B. The content of total sugar was in the order of B>A>D>C. In the sensory evaluation of children's kimchi prepared with four kinds of red pepper powder, the color and total acceptability of kimchi prepared with A were found to be the best. The results of sensory evaluation between kimchi prepared with A and school supplied kimchi showed that the former was better. And the composition of A red pepper powder was as follows: capsaicin equivalent 24.15㎎%, total sugar content 15.79% and ASTA color value 178.2.

This study was performed to investigate the effect of kimchi intake on free radical and oxidative substance production in young adults and the elderly. Daily kimchi intake by people in their twenties (n = 93, 20 to 29 years old) and over sixty-five (n = 143, over 65 years old) in M city were surveyed and blood was drawn to analyze the free radicals in their plasma. The average amount of kimchi intake by the subjects was 115.8 ± 91.7 g. The amount of kimchi intake of those in their twenties (106.1 ± 80.6 g) was significantly lower than that of those over sixty-five (125.5 ± 102.9 g, p < 0.05). Concentrations of total free radicals and OH radicals were 27 and 33% greater respectively, in those over sixty-five than in those in their twenties, indicating that more free radicals were produced by the older group. The concentration of GSH was not signiacantly different in the two groups, but that of GSSG in the over sixty-five age group was 53% greater than in the twenties group, which resulted in a 35% reduction in GSH/GSSG in the elderly group. TBARS concentration in the over sixty-five group was 26% greater than that of the twenties group. In order to see the effect of kimchi intake on free radical production, subjects in same age group were divided into two sub groups-the mean over and the mean under groups-according to the average amount of kimchi intake, which was 115.8 g. The total free radicals, the OH radicals, the GSH, the GSSG, and the GSH/GSSG in the twenties group were not significantly different in the two kimchi intake groups. However, those in the over sixty-five group were significantly different. The concentration of total free radicals and OH radicals of the mean over group were 21 and 26% lower respectively, than those of the mean ova. group (p < 0.05). The GSH and GSH/GSSG of the mean ova. groups were higher by 8 and 12%, respectively. The correlation coefficient between the kimchi intake and the total free radicals was -0.1862 (p < 0.05) and that for GSH/GSSG was 0.1861 (p < 0.05). In conclusion, the production of free radicals and oxidative substances increased with age, and kimchi seemed to retard this phenomena.

김치의 용매획분중 in vitro에서 LDL 산화억제 활성이 강했고 in vivo에서 지질저하 효과가 있었던 디클로로메탄 획분, 에틸아세테이트 획분, 수용성 획분이 고콜레스테롤 식이를 섭취한 토끼의 심장, 신장, 그리고 폐에서 항산화 효소의 활성에 미치는 영향을 살펴보았다. 과산화물 함량은 심장이 가장 높고 신장이 가장 낮았으나, catalase와 GSH-pxghkf성은 심장이 낮았고, 신장은 높은 활성을 나타냈다. Catalase, GSH-px 및 SOD의 활성은 모든 장기에서 1% 콜레스테롤 식이를 섭취한 대조군에 비해 김치 용매획분군에서 낮았고 특히 디클로로메탄 획분군의 항산화효소 활성은 유의적으로 낮았다(p<0.05). 이러한 결과는 김치 용매획분은 심장, 신장 그리고 폐에 지방축적을 억제하는 효과가 있었고, 그로 인해 지질 유리기의 생성이 적어, 각 장기에서 유리기를 제거하는 항산화 효소의 활성이 낮은 것으로 생각된다. The effects of dichloromethane (CH_(2)Cl_(2)), ethylacetate (EtOAc) or water (H_(2)O) fraction of Korean cabbage kimchi on anti-oxidative enzyme activities of the heart, kidney and lung of rabbit fed 1% cholesterol diet for 16 weeks were studied. The amount of kimchi fraction added to the 100g of diet was 8.3mg of CH_(2)Cl_(2), 5.6mg of EtOAc, and 221.9mg of H_(2)O, which are equivalent to 5% of freeze-dried kimchi in the diet. Each group had 6 rabbits and rabbit was housed individually. Lipid peroxide values for the heart was the highest followed by lung and kindey. But the activities of catalase and GSH-px were the lowest in the heart and the highest in the kidney. Activities of anti-oxidative enzymes (catalase. GSH-px, Mn-SOD, Cu, Zn-SOD) of rabbits fed kimchi solvent fractions added diets were lower than those of the control which fed 1% cholesterol diet. Among kimchi groups, CH_(2)Cl_(2) group showed the lowest(p<0.05) enzymes activities. Lipid accumulation in these organs fed diets with kimchi solvent fractions, especially with CH_(2)Cl_(2) fraction, were lower than that of the control. Therefore, production of the lipid free radicals might be suppressed and the activities of anti-oxidative enzymes responsible for removing the free radicals seemed to be lowered in kimch frachoin-fed rabbits.

본 연구는 김치가 노화와 직접적인 관련이 있는 유리기 생성 및 항산화 효소활성에 미치는 영향을 살펴보기 위하여 배추김치, 배추갓김치 그리고 갓김치를 식이중량의 5% 첨가하여 실험식이를 제조하여 이를 노화촉진쥐인 SAMP8에게 1년간 섭취시켰다. 총유리기, OH radical, H_2O_2농도 그리고 TBARS 농도 모두 가령에 따라 증가하였으며, 김치섭취시 유의적으로 감소되었다(p<0.05), 김치군에 있어서 생성된 유리기를 제거하기 위해 항산화계 효소인 SOD, catalase, GSH-px 그리고 GSH/GSSG는 모든 김치군에서 유의적으로 증가 하였다(P<0.05). 따라서 김치섭취는 먼저 가령에 의해 생성되는 유리기의 생성은 억제시키면서, 둘째 이를 제거하기 위한 항산화계 효소 활성은 더욱 활성화시키므로써 항노화 기능을 발휘한다고 생각된다. 김치종류 중에서는 배추갓김치와 갓김치가 배추김치보다 유리기 생성을 억제하고, 항산화계 활성을 증진시킨 것으로 보아 이들의 항노화 효과가 클것으로 생각된다. This study was performed to investigate the effect of kimchi intake on antiaging characteristics in the brain of senescence-accelerated mouse (SAM) in terms of free radical production and anti-oxidative enzymes. Two hundreds twenty SAM (20 mice) were divided into four groups and fed kimchi diet for 12 months. Experimental groups were kimchi free AIN-76 diet (control) group, Korean cabbage kimchi diet (KCK)group, 30% mustard leaf added Korean cabbage kimchi diet (MKCK) group, and mustard leaf kimchi diet (MLK) group. Concentrations of total free radical, OH radical and H_2O_2 of control group increased up to 123%, 262% and 174% of initial value (p<0.05) after one year. Increase in free radical production in kimchi groups due to aging was decreased by kimchi feeding. Among kimchi groups. MKCK and MLK groups showed greater inhibiting effect against free radical production than KCK. The concentration of TBARS in the bruin of control group also significantly increased up to 362% of initial value as aged (p<0.05) and production of TBARS in kimchi groups were decreased. When the activities of Cu, Zn-SOD, Mn-SOD, GSH-px and catalase of kimchi groups were compared to those of control at the same experimental period, anti-oxidative enzyme activities of kimchi groups were lower than those of control (p<0.05). But GSH/GSSG in kimchi groups were higher compared to control. In conclusion, decrease in free radical production and increase in anti-oxidative enzyme activities were observed from kimchi groups suggesting that kimchi might have important role on retarding aging. Among kimchi variety tested in this experiment, MKCK and MLK seem to have greater effect on inhibiting free radical production and increasing anti-oxidative enzyme activities than KCK.

The protective effects of L-arabinose and sugar beet (SBP) on high glucose-induced oxidative stress were investigated using LLC-PK cells. Under the high glucose-induced cellular oxdative model, the treatment of 45 mM of glucose led to the decrease in cell viability and increase in lipod peroxidation_However. L-arabinose and SBP significantly inhibited the high glucose-induced cytotoxicity and lipid per-oxidation. In addition, the formation of nitric oxide(NO) was increased by the treatment of 45mM glu-cose. while the treatment of L-arabinose or SBP inhibited signigicantly the NO formation compared with high glucose-treated control. The superoxide anion production of groups treated whth L-arabinose or SBP was significantly lower than that of the control treated with high glucose. Futhermore. L-arabinose and SBP elevated the glucose uptake. resulting in lower glucose concentration compared with non-treated control. High glucose levels induced the overexpressions of bax. inducible NO synthase and cyclooxygen-ase-2. but L-arabinose or SBP treatrnent down-regulated the expressions of these genes. Arabinose and SBP also inhibited the expression of nuclear factor-kappa B induced by 45mM glucose in LLC-PK cells. In particular, arabinose exhibited stronger inhibitory activities on high glucose-induced oxdative stress than SBP did. These findings indicate that L-arabinose and SBP are promising antioxidative agents with protective activities against hyperglycemia.
