평균연령의 증가에 따른 인구고령화는 현대사회의 공통적 당면과제이며, 이에 따른 퇴행성 근감소증의 발생 및 증가는 이에 대한 새로운 해결책을 요구한다. 근감소증은 단백질의 불균형 및 운동부족, 염증 증가 등 다양한 요소에 의해 발생하므로, 과학적 원인분석을 통한 다각도적 접근이 필요하다. 이는 식품산업의 새로운 블루오션을 창조 할 수 있으나, 현재 국내의 근감소증 개선 식품성분에 관한 연구는 태동 단계라고 할 수 있다. 제품 개발 현황의 경우 단백질을 이용한 제품이 대다수인 반면, 미국의 경우 단백질 유래 원료뿐만 아니라 현미, 갈조류, 사과껍질 등 식물 유래 원료를 이용하여 다양한 제품을 출시하고 있다. 또한, 근감소증 개선 효과가 있는 원료에 대한 특허 출원 은 증가하는 추세지만, 지표성분에 대한 연구는 아직 미비하다. 국내와 비교했을 때 미국을 비롯한 국외 학계 및 산업계는 비교적 많은 연구와 개발을 이루고 있다. 하지만 제품의 소재가 주로 대두단백 및 유청단백 등에만 국한되어 있으며, 운동보조제 위주의 접근으로 인해 제형의 한계가 존재하는 상황이다. 따라서, 근감소증을 개선할 수 있는 다양한 과학적 기작 연구와 함께 소재개발을 통하여 식품 산업의 새로운 시장을 열어갈 선구적 연구가 필요하다.

Whole grain cereal (WGC)-rich diets provide macronutrients that are important for the regulation of energy metabolism. The current study evaluated whether WGCs had a preventive effect on sarcopenic obesity in high-fat diet (HFD)-induced obese mice. C57BL/6N mice were fed a normal diet (ND), ND+WGC, HFD, and HFD+WGC for 12 weeks. WGCs significantly reduced body weight gain, food efficiency ratio, fat mass, and adipocyte size in HFD-induced obese mice. WGCs attenuated HFD-induced nonalcoholic fatty liver disease by decreasing liver weight and hepatic fat accumulation. In addition, WGCs increased muscle strength and muscle mass in HFD-induced obese mice as well as in ND mice. Taken together, WGCs can be employed as functional food materials for the prevention of sarcopenic obesity by inhibiting fat accumulation and increasing muscle mass.

Proximate analysis and antioxidant activity of cultivated wild Panax ginseng (CWPG) were investigated to provide fundamental information of CWPG with different ages and to increase its industrial application. Proximate analyses of CWPG with different ages were performed. Extraction of CWPG with different ages was carried out using heatreflux extraction, and their extraction yield, crude saponin content, ginsenoside content, and antioxidant activity were analyzed. Moisture content decreased, but crude fat and crude protein were increased with aging. Extraction yield and crude saponin contents did not show a specific pattern while 5-year-old CWPG revealed the highest extraction yield and crude saponin content. All CWPGs showed typical ginsenoside profiles containing C-K and Rh2 ginsenosides, which are not found in ginseng. The 3-year-old CWPG showed the highest antioxidant activity including total phenolic content, total flavonoid content, and DPPH and ABTS radical scavenging activities. Moreover, 3-year-old CWPG also revealed the highest acidic polysaccharide content. Therefore, these results suggested that 3-year-old CWPG, which is the cheapest, can be used in industrial application due to its high antioxidant activity and acidic polysaccharide content with similar ginsenoside profile compared to 5- and 7-year-old CWPGs.

It is well-known that cultivated wild Panax ginseng has anti-inflammatory effect. However, a comparative study on cultivation period vs biofunctionality is currently lacking. In this study, 70% ethanol extracts of 3-years (yrs)-, 5-yrs-, or 7-yrs-old cultivated wild ginseng were evaluated for their inhibitory effects on RAW264.7 murine macrophages. Specifically, the production of pro-inflammatory cytokines (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-α]), the expression of surface proteins (CD80, CD86, and MHC-II), and the phagocytic properties were investigated. RAW264.7 cells were induced by 500 ng/mL of lipopolysaccharide (LPS) and treated with 0.1, 1, and 10 ppm of samples. LPS-induced IL-6, TNF-α and surface proteins in all samples were downregulated in a dose-dependent manner. Both IL-6 and TNF-α were significantly reduced at 10 ppm of the 7-yrsold sample compared to 10 ppm of 3-yrs- and 5-yrs-old samples. CD80 and CD86 were also reduced at 10 ppm of all samples, and there was no difference among samples. The phagocytosis has no difference except in 10 ppm of 3 yr-old sample. The results suggest that cultivated wild ginseng extract has anti-inflammatory effect without decreasing phagocytosis.

How to appropriately apply the theories of oriental diet therapy in terms of direction and development are pressing concerns. To address these concerns, this study was performed to provide basic ideas to further the understanding oriental medicinal cuisine(Yack-Sun) and aid its application. Presently, basic data on the nutritional composition and oriental diet therapy area approach of Reajerksodo-rang was acquired to predict the usefulness of Reajerksodo-tang as an edema-related diuretic to promotes urination, drains heat and leaches out dampness. Reajerksodo-tang energy was 67.3 kcal per 100 g, crude protein was 77.2 g, crude fat was 5.7 g crude ash was 0.6 g and carbohydrate was 16.5 g per 100 g. This basic data could help guide the application of oriental medicinal resources into other foods and serve as a stepping-stone for use of Reajerksodo-tang in the burgeoning field of function foods. Lastly, the scientific effects of oriental medicinal foods developed according to oriental medicinal theory. It is believed to be essential for government policy development concerning validation of medicinal effects and assessment, with the aim of fostering systematic development and providing guidance to food development in the interest of national health.

옥수수기름의 탈취온도가 trans 지방산 생성량 및 그 조성에 미치는 영향을 GLC를 이용하여 측정하였다. 상대적으로 저온탈취인 240∼250℃에서는 극미량의 trans 지방산만이 검출되었으나, 고온탈취인 255∼270℃ 구간에서는 0.30, 0.57, 0.64 및 0.81%를 나타내었다. 이성화 현상은 이중결합수가 증가할수록 두드러졌으며, tt 및 ttt형은 거의 검출되지 않는데 비하여 ct, tc, cct 및 tcc형이 다량 검출되었다. 따라서, 탈취유의 이화학적 특성과 함께 이성체형성의 극소화는 저온탈취에 의하여 최대의 효과를 얻을 수 있음을 확인하였다.

Jujube paste was prepared by autoclaving the fresh jujube at 1.2 atm and 120℃ for 30 min and removing the skin and cores. In order to increase the juice yield, the paste was treated with pectinase, cellulase and their combinations. The soluble fractions of enzymatically treated jujube paste were characterized in terms of yield, pH, titratable acidity, color, Bx, transmittance and sugar compositions. The original paste exhibited the water soluble fraction of 57.3%. Of various quality factors, the clarity was the most significantly distinguished between pectinase and cellulase treatments. The cellulase treatment produced the cloudy juice with the yield of 83.60%. On the other hand, the clear juice was produced by the pectinase and combined treatments due to degradation of pectins, whose yields were 79.47% and 85.39%, respectively. The results clearly demonstrated that the pectinase treatments improved the solubilization efficiency and clarity.
