This study was performed to investigate the effect on polyunsaturate fatty acid diets and feeding periods on the antithrombosis. the hematological changes in the blood and fatty acid compositions of platelets in rats. Each group of rats was fed a diet containing 20%(W/W) corn oil beef tallow sardine oil and the general stock diet for 10, 20. 40 and 80 days. Rats fed sardine oil diet showed significantly longer bleeding time than any other diet groups after 20 days feeding The whole blood clotting time of sardine oil group fed for 80 days was increased significantly. The number of platelet and the concentration of hemoglobin showed no significant difference among all groups. The number of white blood cell was decreased continously in sardine oil group after 10 days feeding. The level of malondialdehyde generation during thrombin-induced aggregation of platelets was decreased continously in sardine oil grou after 20 days feeding. With regard to the composition of platelet fatty acid the ratio of eicosapentaenoic acid(EPA 20: 5 $\omega$-3) to arachidonic acid(AA 20:4 $\omega$-6) was increased in sardine oil group but decreased in corn oil groups and beef tallow groups with days. In conclusion the rats fed sardine oil diet for more than 20 days showed the fact that EPA induced the antithrombosis. the changes in number of white blood cell and the fatty acid composition of platelets.

We hypothesized the primary effect of ginseng was to protect cell membrane fatty acids from decomposition caused by free radicals. To confirm the antioxidant effect of ginseng, we measured the inhibitory effect on the formation of thiobarbituric acid-reactive substances, an indicator of lipid peroxidation, and evaluated the free radical scavenging effect of ginseng by electron spin resonance spectrometer, and gas chromatography. The results showed that thiobarbituric acid-reactive substances formed and the loss of arachidonic acid during lipid peroxidation, and that hydroxyl (-like) radical peak formed by the iron complex (ferric nitrilotriacetate, an known free radical generator in vitro) were completely inhibited by ginseng extract. This antioxidant effect of ginseng may be responsible for its wide pharmacological actions in clinical practice. As the free radical reactions in general are rapid and non-specific, ginseng seems to act as a normalizer, rather than a general tonic, at the stages of acute or chronic active phase of the various diseases.

혈중 콜레스테롤 농도를 저하시키는 건강지향적인 불포화 지방산을 다량 함유한 옥배유로 원료유 지방을 표준화하여 cholesterol free Mozzarella cheese제조 후 특성을 살펴 보았다. 치즈 제조용 원료유는 안정성이 있었고, 최종 시료인 치즈에서 휘발성 유리지방산은 콜레스테롤 상승에 영향을 미치는 palmitic acid가 일반 치즈인 대조구에서 가장 높게 측정된 반면에 실험구인 옥배유를 첨가하여 만든 치즈는 동맥경화 및 성인병 등의 예방, 치료에 도움을 주는 linoleic acid 조성 이 가장 높게 나타나 영양학적으로 우수한 결론이 돌출되었다. 포화지방산에 대한 불포화지방산의 비율은 대조구가 7:3, 옥배유를 첨가하여 만든 치즈가 2:8로 나타났으며, 콜레스테롤은 대조구의 43.58 mg/100 g에 비해 옥배유를 첨가하여 만든 치즈는4.34 mg/100g만 측정되어 건강에 유의한 결과가 나타났다. 결과적으로 본 연구는 혈중 콜레스테롤 저하효과를 나타내는 휘발성 유리지방산을 다량 함유하고, 콜레스테롤 함량이 대조구의 10%수준인 영양학적으로 우수한 건강지향적인 cholesterol free Mozzarella cheese를 제조할 수 있었다.

This study was performed to evaluate the quality characteristics of functional Dasik prepared with a mixture of freeze-dried mealworm (Tenebrio molitor) powder and dried pollack powder along with assessment of the general and fatty acid compositions of mealworms. General compositions, except for moisture content of freeze-dried mealworm powder, were higher than those of raw mealworms. The ratios of saturated fatty acids and unsaturated fatty acids of freeze-dried mealworm powder and raw mealworms were 1:3.31 and 1:3.19, respectively. Amounts of oleic acid, which was the most abundant among unsaturated fatty acids, of freeze-dried mealworm powder and raw mealworms were 41.12 and 37.84%, respectively. For color values, greater content of freeze-dried mealworm powder in functional Dasik resulted in lower L and b scores, whereas a value increased. In the case of mechanical properties, greater content of freeze-dried mealworm powder resulted in significant reduction of hardness, chewiness, and gumminess. In the case of sensory evaluation, color, taste, and overall quality of DPMD50, which was prepared with a 1:1 ratio of freeze-dried mealworm powder and dried pollack, were the highest. It was concluded that DPMD50 is a nutritious combination of edible insects and fish for protein fortification for growth and the elderly.

The purpose of this study was to investigate the possibility of Meles moles application as an edible functional food resource. This study was conducted to estimate the general nutrition composition, amino acid and minerals contents, fatty acid composition of Meles meles oil and the added fermented medicinal herbs liquid, and examine the cell toxicity effects in normal liver and kidney cells. The approximate composition of Meles moles oil was crude fat, 97.64％, crude ash, 1.99％ and crude protein, 0.37％. In the fermented liquid, the approximate composition was moisture, 96.08％, Carbohydrate, 1.53％, crude ash, 0.92％, dietary fiber, 0.65％, crude protein, 0.54％ and crude fat, 0.28％. The amino acid contents were 2.67 and 80.9mg％ in the oil and liquid, respectively. The singularity of the unsaturated fatty acid contents attracted our attention. Especially, the polyunsaturated fatty acid compositions were 32.28 and 54.98％ in oil and liquid, respectively. Negative effects were not found form the results of the cell toxicity respection. These results imply that Meles effects oil and the added fermented medicinal herbs liquid can be used as possible food resources and functional food materials.

This study was carried out to prepare green teas by traditional roasting manufacturing process, Ku Geung Ku Po and to determine the quality charateristics of the green teas by examining the change of their main components induced during this roasting process. The content of total sugars in unroasted tea leaves was 7.82%. Its content of roasted teas was decreased by increasing the number of roasting and there was significantly differences between samples. The content of total sugars in 9th roasted green tea was 3.98%. The total nitrogen contents of green teas produced by this process were 4.96∼6.38%. The more the number of roasting and the less content of tannin in green teas. And the ratio of total nitrogen and tannin in tea leaves 21.97 but its ratio in 9th roasted tea was increased to 45.54. The ascorbic acid in tea leaves consisted in 1,820.3 mg/100g but its content was decreased by increasing the number of roasting process. Whereas the content of caffeine in green teas was not reduced significantly by this traditional method. Of all amino acids, green tea produced by Ku Jeung Ku Po was rich glutamic acid, lysine and aspartic acid. And especially, phenylalanine, which was rarely found in other green teas, was abundant in these green teas. The compositions of glutamic acid and methionine were increased as increasing the number of roasting process but those of aspartic acid and arginine decreased by these processing. The main fatty acids of Ku Jeung Ku Po green tea were linolenic acid, linoleic acid and palmitic acid and the contents of unsaturated fatty acid in green teas were composed over 70% of total fatty acid. And the fatty acid contents in green teas were not affected during Ku Jeung Ku Po's process. The contents of minerals in these teas was rich in the oder of potassuim. magnessuim and calciumim, and these contents were not observed the prominant change during the process.
