  • 본 연구는 쉬리(Coreoleuciscus splendidus)를 대상으로 사료내 색소원으로서 paprika 및 spirulina 첨가와 원료 각각의 첨가량을 달리하여 쉬리의 생존율과 색택개선에 미치는 영향을 조사하였다. 실험어는 평균체중 약 4.4 g인 쉬리를 사용하였으며, 총 8개(Control, P1, P2, P3, S1, S2, S3 및 P2+S2)의 실험 사료를 설계하였다. 사료 P1, P2 및 P3는 paprika를 각각 2%, 5% 및 10%를 첨가하였으며, 사료 S1, S2 및 S3는 spirulina를 각각 5%, 10% 및 20%를 첨가하여 제조하였다. 또한 P2+S2 사료는 paprika 5%와 spirulina 10%를 혼합하여 제조하였다. 실험종료 후, 쉬리의 생존율은 spirulina가 첨가된 모든 실험구인 S1, S2, S3 및 P2+S2에서 100%로 대조구(80%) 및 paprika 첨가구($73{\sim}93%$)보다 높게 나타났다. 쉬리의 표피 및 지느러미의 총 carotenoids 함량은 색소원이 첨가되지 않은 대조구에서 1.58 mg/100 g으로 가장 낮았으며, spirulina 10% 첨가구인 S2 실험구에서 2.23 mg/100 g으로 가장 높았다. Paprika와 spirulina가 혼합되어 첨가된 실험구인 P2+S2는 1.61 mg/100 g으로 paprika와 spirulina가 각각 첨가된 P2 (2.14 mg/100 g) 및 S2 (2.23 mg/100 g)보다 낮은 총 carotenoids 함량을 보였다. 쉬리의 표피를 육안으로 관찰한 결과 색소원이 첨가된 모든 실험구에서 대조구에 비하여 체색이 더욱 선명화 됨을 관찰 할 수 있었다. 이상의 결과를 고려할 때, 쉬리의 사료내 paprika 첨가시 5%, spirulina 첨가시 10%가 쉬리의 색택개선에 좋을 것으로 판단된다.

  • To examine the effects of residual phosphorus content on color reversion and storage stability of corn germ oil, the changes of Lovibond total color and stability of oxidation were determined according to the different storage periods at room and incubating temperature, respectively. The residual phosphorus content and storage temperature had the synergistic effect on color reversion during short time storage. The extent of color change was the greatest when oils were stored for 1.0∼1.5 years at room temperature and thereafter gradually tended to reverse color reversion. It is supposed that the double bonds of carotenoids in oils were oxidized and then turned to the volatiles such as epoxide, ionone, and etc. In contrast, the residual phosphorus content increased oxidation stability of oils. The residual phosphorus content was closely correlated with the color reversion and storage stability, respectively.

  • Carotenoids liberated from the red carotenoprotein from the skin of ascidian(Halocynthia roretzi)were developed on TLC, and two bands were obtained with different Rfvalues. Their chemical reactivities and spectroscopic properties were studied and elucidated as astaxanthin diester and astaxanthin monoester. After saponification of carotenoid ester, GC analysis was performed. The carotenoid ester contained oleic acid, palmitic acid and palmitoleic acids as 50% of total amount, and had higher content unsaturated fatty acid including eicosapentanoic acid than saturated fatty acid.

  • Paprika (Capsicum annuum L.) contains various phytochemicals, including carotenoids, ascorbic acid, tocopherol, flavonoids, and phenolic compounds, as well as natural food colorants. Very little information is available regarding wine produced from different colored paprikas. The objectives of this study were to prepare wines from red, orange, and yellow paprika and evaluate their physicochemical characteristics. The alcohol concentration, pH, titratable acidity, and reducing sugar content were not significantly affected by the type of paprika. Hunter's color values varied with the color of paprika. The total mineral content and 2,2-diphenyl-1-picrylhydrazyl radical scavenging potential of red paprika wine were significantly higher; however, the total polyphenol content of yellow paprika wine was significantly higher than that of the other wine samples. This study suggested that paprika could be used to prepare wine and red paprika might be appropriate for producing good-quality wine.

  • The consumption of fruits and vegetables that have high polyphenol content has been previously associated with a reduced risk for cardiovascular disease. We investigated the effects of onion peel extract on plasma total antioxidant capacity, lipid peroxidation, and leukocyte DNA damage. This study was a randomized, double-blind, placebo-controlled, crossover trial. Healthy female subjects received either onion peel extract or placebo (dextrin) for two weeks, underwent a 1-week washout period, and then received the other treatment for an additional two weeks. After two weeks of onion peel extract supplementation, the total cholesterol level, low-density lipoprotein cholesterol level, and atherogenic index significantly decreased (P < 0.05). No changes were observed in activities of erythrocyte antioxidant enzymes or levels of lipid peroxidation markers following onion peel extract supplementation. Additionally, no significant difference was found in plasma antioxidant vitamin (retinol, tocopherols, carotenoids, and coenzyme Q10) levels or ex vivo $H_2O_2$-provoked oxidative DNA damage after onion peel extract supplementation. The present interventional study provides evidence of the health benefits of onion peel extract and demonstrates its effects in modulating lipid profiles in healthy young Korean women.

  • This study was carried out to prepare green tea by traditional roasting process, Kujeungkupo, and to determine its sensory characteristics. The carotenoid content in green tea was increased by roasting and reached 1,317 mg/100 g by Kujeungkupo. Of all carotenoids, the contents of lutein and $\beta$-carotene were 1,170 mg/100 g and 111.1 mg/100 g, respectively. The total cathechin content in green tea was 14.57 g/100 g after 9th roasting. The more the number of roasting the little contents of cathechin in green teas. Of all cathechin, epigallocathechingallate was the highest(6.80g/100 g) followed by epicathechingallte and epicathechin. total cholrophyll content was 141 mg/100 g of green tea. The free sugar content in Kujeungkupo green tea wet 2.18 g/100 g, of which sucrose comprised 46% (1.01 g/100 g). The color value ($\Delta$E) of Kujeungkupo green tea was 16.25. In sensory evaluation, sweet taste was the highest in green tea roasted 3 times and the flavor was best in that roasted 5 times. The sweet and astringent tastes of green tea had negative relationships with a and b values. The content of cathechin in green tea had a negative relationship with sweet taste and a positive relationship with astringent taste.
