Dasik is a type of Korean traditional confectionery that is kneaded with various grains, nuts or herb flour and honey and then pressed with a decorative press. Soybeans are a rich in protein, lipids, dietary fiber, minerals and fat soluble vitamins. Spirulina is a functional food that contains protein, lipids, carbohydrates, minerals, vitamins, dietary fiber and pigments. In this study, soybean Dasik containing spirulina was developed in an attempt to provide an easy method of incorporating spirulina into daily dietary life. In addition, we evaluated the quality characteristics of the soybean Dasik with spirulina that was developed here. Specifically, 0, 10, 20 and 30% spirulina was added to the soybean powder that was used to prepare soybean Dasik. Soybean Dasik that contained 30% spirulina had a higher moisture content and lower hardness when compared to other groups. In addition, the L, a and b value decreased as the level of spirulina increased. Furthermore, the antioxidant activity of soybean Dasik increased according to the increase in the addition of spirulina. Specifically, the $IC_{50}$ values of the DPPH and hydroxyl radical scavenging activity of the control group were 76.6 mg/mL and 100.7 mg/mL, respectively, whereas these values were 26.3 mg/mL and 32.9 mg/mL, respectively, in Soybean Dasik that contained 30% spirulina. When a sensory evaluation was conducted, the overall preference decreased as the level of added spirulina increased. When the buying intension was evaluated, the control group had the highest score (7.8), followed by that of the Dasik that contained 20% spirulina (7.2) The buying intention was lowest for the Dasik that contained 30% spirulina. In conclusion, Soybean Dasik that contained up to 20% spirulina would be maketable.

This research was designed and implemented to evaluate how the composition of yaksuncha can affect the health of individuals suffering from diet-related diseases such as obesity and hyperlipidemia by prescribing Yaksun as a nutritional supplement with daily meals. The yaksunucha was prepared as Koekac, Sansa, Heshouwu and Woolong tea and the tea's effects on serum lipids and oxidative stress were evaluated by clinical procedures. The yaksuncha significantly increased HDL-cholesterol and decrease of LDL-cholesterol concentrations in serum. It also had significant effects on decreasing oxidative stress and homocystein levels. The physical characteristics of the yaksunucha were also examined, showing. Brix, pH and titratable acidity values of 1.4, 5.50 and 0.05% respectively. It is thought that scientific and objective evaluations were completed on the components of the yaksuncha prescription. Thus one can concluded that the components could be applied not only in the form of tea, but also various food. The data derived from this study provides basic information that will aid in the application of oriental medicinal resources to other foods as well as facilitate the study of medicinal herbs within the field of functional food research, which already draws sizable attention worldwide.

Postmenopausal women are at an increased risk of developing coronary artery disease. This is due to primarily dyslipidemia accompanying the loss of estrogen secretion. Soy isoflavones are known to have weak estrogenic effects. The purpose of this study is to investigate whether isoflavone supplement improves the risk of cardiovascular disease in hypercholesterolemic postmenopausal women. Subjects consisted of 39 Korean postmenopausal women with hypercholesterolemia (total cholesterol $\geq$ 200 mg/㎗ or LDL cholesterol $\geq$ 130 mg/㎗). Subjects were divided into 2 groups; placebo group (PG), isoflavone supplement group (IG). During 12 weeks, subjects were given placebo and 80mg isoflavone daily. Anthropometric measurement, blood sample analysis and dietary intake measurement were taken at baseline and after 12 weeks. After 12 weeks, systolic blood pressure was decreased significantly (p ＜ 0.01) and plasma HDL cholesterol level was increased significantly (p ＜ 0.05) in IG. But there were no significant changes in plasma total cholesterol, LDL cholesterol and triglyceride levels after isoflavone supplementation. There was a negative correlation between initial plasma HDL cholesterol level and the extent of plasma HDL cholesterol reduction in IG (r＝-0.572, p＝0.012). Atherogenic index (AI), total-/LDL- cholesterol ratio and LDL/HDL cholesterol ratio were improved significantly after isoflavone supplementation. In subjects whose initial plasma LDL cholesterol level were above 160 mg/㎗, plasma malondialdehyde (MDA) level were decreased and total antioxidant status (TAS) were increased significantly after isoflavone supplement (p ＜ 0.05). However there were no significant changes in flow-mediated dilator (FMD), the marker of endothelium-dependent vasodilation and nitroglycerine-mediated dilator (NMD), the marker of endothelium-independent vasodilation and the extent of DNA damage after isoflavone supplement. In conclusion, these results indicate that isoflavone supplement may decrease the risk of cardiovascular disease via improving blood pressure, HDL cholesterol level and AI in hypercholesterolemic postmenopausal women. Futhermore, in case of subjects with elevated LDL cholesterol level, isoflavone supplementation may have more antiatherogenic effects via improving antioxidant status.

환경문제에 대한 관심이 증가함에 따라 지속가능한 소재에 대한 요구가 증가하고 있다. 전 세계적으로 커피는 가장 많이 소비되는 음료이며, 커피음료의 가공 및 소비로 발생하는 커피 부산물에는 셀룰로오스, 헤미셀룰로오스, 리그닌, 지질 및 생리활성물질 등이 풍부하지만 대부분 폐기되는 실정이다. 따라서, 많은 연구자들이 커피 부산물을 고부가가치 소재로 개발하기 위하여 노력하고 있다. 본 총설에서는 고분자/커피 은피 복합화 연구, 커피 은피로부터 셀룰로오스 추출 및 응용연구, 고분자/커피찌꺼기 복합화 연구, 커피찌꺼기로부터 셀룰로오스 추출 및 이를 활용한 연구, 커피찌꺼기로부터 지질 추출 및 이를 활용한 PHAs합성, 가소제로써 커피찌꺼기로부터 추출한 지질의 응용가능성 연구 등에 대하여 조사하였다. 선행 연구에서는 커피 부산물인 커피 은피 및 커피찌꺼기 자체를 고분자와 혼합하여 복합소재를 제조하고 물성을 평가하는 연구는 광범위하게 수행되고 있는 것으로 확인되었다. 하지만, 커피 은피 및 커피찌꺼기로부터 나노셀룰로오스를 추출하거나, 상대적으로 친수성인 커피 부산물과 소수성인 석유계 고분자 또는 생분해성 고분자와 복합화 시 상용성 개선과 관련된 커피 부산물의 표면 개질 및 상용화제 도입 등의 연구는 부족함을 확인하였다. 또한 커피 부산물로부터 추출한 지질을 활용하여 PHAs를 합성하는 연구가 일부 진행되고 있지만 합성된 PHAs를 활용하여 포장소재로의 제조 및 응용에 관한 추가적인 연구가 필요하다고 사료된다. 또한, 커피찌꺼기의 발생량 대비 국내외 관리방안 마련 및 제품 적용 시 안전성 평가방법에 관한 연구는 거의 실시되지 않아 이에 대한 추가적인 연구가 필요하다고 판단된다.

In order to investigate whether Eisenia bicyclis (EB) as a functional food material improves serum lipid status, supplementation of EB powder or EB extract to the high fat/cholesterol diet was tested in 6-week old male Sprague-Dawley rats for four weeks. In the first experiment, four kinds of seaweed powder -Eisenia bicyclis (EB), Undaria pinnatifida (Up), Laminaria japonica (LJ), and Ecklonia stolonifera (ES) were compared with alginic acid (ALG) as well as control. In the second experiment, EB water extract and EB ethanol extract and EB pill containing EB and LJ powder were compared with the EB powder. Amounts of dietary fiber contained in experimental diets were adjusted to provide 5% of diets. Serum total cholesterol was significantly lower only in rats fed LJ or EB powder, but HDL cholesterol was higher in rats fed UP, LJ, ES or EB powder. Ratios of HDL-/total cholesterol of all seaweed groups including ALG were significantly higher than that of the control group. Serum triglyceride was lower in LJ, EB nd ES powder groups than the control group. In comparison of EB extracts, triglyceride level was decreased in rats fed only EB water extract as compared to control rats, but HDL cholesterol was elevated with both water and ethanol extracts. Serum levels of total cholesterol, triglyceride were decreased and HDL cholesterol was increased by the EB pill. Serum levels of thiobarbituric acid-reactive substances were lower in rats fed ES powder, and EB powder, EB water extract or EB pill, as compared to the control rats. Supplementation of EB powder and EB pill reduced serum level of GOT and GPT, respectively, as compared to the control group. In conclusion, EB and EB pill improve serum lipid status and may be utilized as ingredient of functional foods for the purpose of improving serum lipid profile and inhibiting peroxidation of lipids.

Microalgae are unicellular microorganisms inhabiting various ecosystems of the world, including marine and freshwater systems and extreme environments. Only a few species have been actively used as food. Microalgae are attracting attention as a means of biological CO2 reduction because they play an important role in absorbing atmospheric CO2 through their rapid growth by photosynthesis in water. Besides, microalgae are considered to be an eco-friendly energy source because they can rapidly produce biomass containing a large quantum of lipids that can be converted into biodiesel. Several microalgae, such as Chlorella spp., Spirulina spp. and Haematococcus spp. have already been commercialized as functional health supplements because they contain diverse nutrients including proteins, vitamins, minerals, and functional substances such as docosahexaenoic acid (DHA), β-glucan, phycocyanin, astaxanthin, etc. Moreover, they have the potential to be used as food materials that can address the protein-energy malnutrition (PEM) which may occur in the future due to population growth. They can be added to various foods in the form of powder or liquid extract for enhancing the quality characteristics of the foods. In this review, we analyzed several microalgae which can be used as food additives and summarized their characteristics and functions that suggest the possibility of a role for microalgae as future food.

New supplements with preventive effects against skin photodamage are receiving increasing attention. This study evaluated the anti-photoaging effects of salmon nasal cartilage proteoglycan (SPG), acting as a functional material for skin health. We administered SPG to in vitro and in vivo models exposed to ultraviolet B (UVB) radiation and assessed its moisturizing and anti-wrinkle effects on dorsal mouse skin and keratinocytes and dermal fibroblasts cell lines. These results showed that SPG restored the levels of filaggrin, involucrin, and AQP3 in the epidermis of UVB-irradiated dorsal skin and keratinocytes, thereby enhancing the keratinization process and water flow. Additionally, SPG treatment increased the levels of hyaluronan and skin ceramide, the major components of intercellular lipids in the epidermis. Furthermore, SPG treatment significantly increased the levels of collagen and procollagen type 1 by down-regulating matrix metalloproteinase 1, which play a crucial role in skin fibroblasts, in both in vitro and in vivo models. In addition, SPG strongly inhibited mitogen-activated protein kinase (MAPKs) signaling, the including extracellular signal-regulated kinase, c-Jun N-terminal kinase (JNK), and p38. These findings suggest that dietary SPG may be an attractive functional food for preventing UVB-induced photoaging. And this SPG product may provide its best benefit when treating several signs of skin photoaging.

This study was to examine the lipid metabolism of fermented Rhynchosia nulubilis (FRN) in obese rats. The abnormal content of blood lipids often results in metabolic diseases, such as obesity and hyperlipidemia. Seven weeks female Sprague-Dawley rats were divided into four groups and fed high fat diets for 44 days. Also FRN was administered orally for 44 days at 7.5 ml/kg of body weight of rats. The effects of the lipid metabolism were evaluated by total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), glutamic pyruvate transaminase (GPT) and glutamic oxalacetic transaminase (GOT) levels in sera. The levels of TC, TG, LDL and GPT in FRN-treated groups were lower than those in obese groups. While HDL levels were significantly increased. These results demonstrated that FRN had improving effects of lipid metabolism in the obese rats, suggesting that FRN would be used as an ingredient of the useful functional products.
