본 연구는 마를 활용하여 마죽을 만든 다음 양념으로 마김치를 제조하였다. 마의 농도는 3%(W/W)로 하여 마맛김치, 마깍두기, 마포기김치를 제조한 다음 영양성분 및 관능 평가를 실시하였으며, 그 결과는 다음과 같다. 시료 100 g 당 3 종류의 마김치 열량은 35~40 kcal이였으며, 조지방, 포화지방, 트랜스지방 및 콜레스테롤은 검출되지 않았다. 나트륨 함량은 450~650 mg으로 마맛김치군 < 마깍뚜기군 < 마포기배추김치군 순으로 높은 함량을 보였다. 3종류 마김치의 비타민 C 함량은 저장 기간 28일에 급격히 높은 증가량을 보였으며, 마깍뚜기에 비해 마맛김치와 마포기배추김치에서의 비타민 C 함량이 크게 증가되었다. 3종류의 마김치 모두에서 Ca, K, Mg의 함량은 높았다. 마김치의 염도는 담금 직후부터 28일까지 맛김치와 깍두기에 비해 포기배추김치 염도가 2.38~ 2.72%의 적정염도를 유지하였다. 맛김치와 배추포기김치는 저장기간이 늘어나면서 명도값은 증가된 반면에 적색도값은 감소되는 경향을 보였으며, 대조군에 비해 마를 첨가한 실험군에서 높은 황색도값을 보였다. 3종류 마김치의 경도는 저장기간이 길어질수록 낮아졌다. 3종류 마김치의 관능검사에서는 대조군과 마를 첨가한 실험군 간에 큰 차이는 없었다. In this study, we produced kimchi with cooked Dioscorea batatas yam. Sliced kimchi cabbage, processed white radish kimchi (kkakdugi), and whole kimchi cabbage were prepared with 3% Dioscorea batatas, the nutritional and sensory properties were evaluated. The three types of D. opposita kimchi showed energy content in the range of 35-40 kcal per 100 g, and no crude fat, saturated fat, trans fat, or cholesterol was detected. Sodium content was 450-650 mg, with sliced cabbage kimchi showing the highest concentration. The vitamin C content increased significantly after 28 days of storage, with the sliced cabbage kimchi and whole-cabbage kimchi showing larger increases than the radish kimchi. All three types of D. opposita kimchi showed high Ca, K, and Mg contents. The whole-cabbage kimchi maintained salinity at a level of 2.38-2.72% from immediately after preparation to 28 days of storage compared to sliced cabbage kimchi and radish kimchi. Sliced cabbage and whole kimchi cabbage kimchi showed an increase in lightness and a decrease in redness with longer storage duration. Compared to the control groups, the experimental groups (with added D. opposita) showed higher yellowness. The hardness of the three types of kimchi decreased with longer storage duration. In sensory evaluation, there were no significant differences between the control groups and the experimental groups.

B. cereus에 대한 지역별 단삼 추출물의 항균 활성은 영양단삼이 가장 높았으며, 열수에 비해 75% 에탄올 추출물의 항균 활성이 더 우수하였다. LPS로 염증을 유도한 RAW 264.7 세포에 지역별 단삼 추출물을 처리하여 NO 저해율을 비교한 결과 열수 추출물에서는 중국산 단삼이 34% 저해율로 가장 높았으나, 75% 에탄올 추출물에서는 고창 단삼이 68% 저해율로 가장 우수한 결과를 나타내었다. 재배지역별 단삼 추출물에서 주요 성분인 salvianolic acid 함량을 비교한 결과 영양 단삼 추출물의 함량이 가장 높았으며, 열수에 비해 75% 에탄올 추출물의 함량이 좀 더 높은 결과를 보였다. The purpose of this study was to compare the chemical components and biological activities of Salvia miltiorrhiza Bunge (SMB) from different cultivation regions (Gochang, Yeongyang, Jangheung, and China). Proximate compositions and contents of total polyphenols and flavonoids were measured. Depending on the cultivation region, proximate composition of SMB showed significant variations. Total polyphenol and total flavonoid contents were highest in Yeongyang SMB and Gochang SMB, respectively. We prepared hot water and 75% ethanol extracts of SMB from different cultivation regions and also investigated the biological effects of extracts on anti-oxidant, antibacterial, and anti-inflammatory activities. Extracts of Yeongyang SMB were the most effective at scavenging DPPH and ABTS free radicals, and hot water extract showed better scavenging activity than 75% ethanol extract. We observed that extracts of Yeongyang SMB exhibited the best antibacterial activity against Bacillus cereus, and 75% ethanol extract showed better antibacterial activity than water extract. Anti-inflammatory activities of SMB extracts from different cultivation regions were investigated through evaluation of their inhibitory effects on production of nitric oxide (NO) in lipopolysaccharides-induced RAW 264.7 cells. At 50 μg/mL, extract of China SMB showed the highest NO inhibitory activity of 34% among water extracts, and extract of Gochang SMB showed the highest NO inhibitory activity of 68% among 75% ethanol extracts. Salvianolic acid B level was the highest in extract of Yeongyang SMB with values of 110.59 mg/g for water extract and 111.93 mg/g for 75% ethanol extract.

Recently, due to lack of physical activity, middle-aged women are exposed to Lifestyle-related diseases by obesity and health care is urgently needed. The purpose of this study was to investigate the effect of complex exercise program on Lifestyle-related factors and blood free oxygen radical of middle-aged obese women. The two-way repeated measure ANOVA was used to verify the difference between the time of measurement and the group. At this time, the paired sample t-test was performed for the variables with statistically significant differences in each variable. The significance level of all results was set to p<.05 and the following conclusions were obtained. In the changes of Lifestyle-related factors, the body fat percentage showed an interaction effect between group and period & group. The blood glucose showed only the interaction effect between period & group. Total cholesterol had an interaction effect between timing and period & group, In neutral fat, there was only interaction effect between timing & group. In blood pressure, there was no interaction effect in time, group and time & group. Also in all the factors of the exercise group, the difference between the two groups was statistically significant after the experiments than before. Changes in blood activated oxygen were found to have an interaction effect between the two groups. In the exercise group, statistically significant decrease was observed after the experiment. In conclusion, complex exercise has a positive effect on improving Lifestyle-related factors and blood stress. This indicates that this can be a recommended exercise method for middle-aged obese women. In future follow-up studies, if the exercise duration is prolonged and the intensity is gradually increased, it can be considered to be a program that can prevent various Lifestyle diseases by eliminating middle-aged obesity.

항효모 활성이 우수한 녹차씨로부터 천연 보존소재를 개발하기 위하여 추출 원료를 최적화하기 위한 녹차씨의 전처리 방법을 평가하였다. 과피 유무에 따른 녹차씨의 추출 결과 추출물의 항효모 활성은 같았으며, 추출 수율은 과피를 제거한 속씨에서 근소하게 높은 것으로 나타났다. 건조에 따른 녹차씨의 수분 함량은 항효모 활성에는 영향을 주지 않았으나 추출 수율은 7.3% 수분 함량에서 가장 높게 나타났다. 분쇄 공정에 따른 녹차씨 추출물의 항효모 활성은 같았으나, 원료의 입도가 작은 믹서 분쇄 원료에서 추출 수율이 더 높게 나타났다. 녹차씨 오일을 추출한 부산물인 탈지 녹차씨를 추출하여 보존소재 원료로써 활용 가능성을 평가한 결과 항효모 활성은 녹차씨 추출물과 같았으며, 탈지 방법에 따라 수율은 다르게 나타나 헥산 추출 탈지 녹차씨보다 압착 탈지 녹차씨의 추출 수율이 더 높게 나타났다. 녹차씨의 전처리 방법 평가에 따라 천연 보존소재를 추출하기 위한 원료로서 과피가 포함된 녹차씨를 수분 함량 7.3%로 건조한 후 롤밀 분쇄하여 착유기로 오일을 추출한 탈지 녹차씨를 제조하였다. 탈지 녹차씨를 추출 용매에 따라 추출한 후 수율 및 항효모 활성을 조사한 결과 경제성이 높은 추출 용매는 물이 적합하였다. 추출 온도 및 시간에 따른 탈지 녹차씨의 추출결과 90°C 추출에서는 항효모 활성이 다소 불안정한 것으로 나타났다. 추출 수율과 항효모 활성의 안정성을 고려하여 물을 용매로 하였을 때 50°C, 4시간 추출 조건이 적합할 것으로 생각된다. Green tea (Camellia sinensis) seed extract (GTSE) was prepared under various pretreatment conditions and used to investigate its extraction yield and anti-yeast activity. Anti-yeast activity of GTSE from seeds with or without the coats was the same, whereas the extraction yield was slightly higher in extract from seeds without the coat. Anti-yeast activity of GTSE from seeds with different water contents or particle sizes was the same, whereas the extraction yield was highest in extract from seeds with 7.3% moisture or a smaller particle size. Anti-yeast activity of defatted green tea seed extract (DGTSE) was the same as that of GTSE. Extraction yield was higher in DGTSE from defatted seeds by the oil press machine compared to hexane extraction. Defatted green tea seed (DGTS), a by-product from the oil extraction process, is a good natural source of anti-yeast preservative. The extraction yield and anti-yeast activity of DGTSE were investigated using various extraction solvents, temperatures, and times. The results show that water was an economic extraction solvent, and anti-yeast activity of DGTSE was unstable at 90°C. These results suggest that water, extraction temperature of 50°C, and extraction time of 4 h were the most efficient for extraction of anti-yeast compounds from DGTS.
