This study was performed to investigate the quality characteristics and antioxidant activity of black soybean Sunsik product with functional food ingredients and functional labeling system. We prepared black soybean Sunsik (BS) containing black beans, cereals, and vegetables. Black soybean Sunsik with nondigestible maltodextrin and calcium lactate (BSN) was prepared by adding non-digestible maltodextrin and calcium lactate to the base recipe to apply a functional labeling system. The particle size in BS was 118.00 μm, whereas BSN was 127.00 μm. The respective L, a, and b color values of BS were 73.25, 2.36, and 14.21. The respective L, a, and b values of BSN were 73.21, 2.36, and 14.31. The respective water retention capacities of BS and BSN were 241.67% and 216.33%. No significant difference was observed between BS and BSN in the three physicochemical properties described above. However, the pH of BSN was 5.45, which was significantly lower than that of BS. The total respective phenolic contents of BS and BSN were 1.75 mg GAE/g and 1.61 mg GAE/g, and total respective flavonoid contents of BS and BSN were 6.36 mg RE/g and 5.95 mg RE/g. The antioxidant capacities of BS and BSN were compared via assays of DPPH and ABTS radical scavenging activities, FRAP, and reducing power. The antioxidant activities of BS and BSN increased in a dose-dependant manner. No significant difference between BS and BSN was observed in any measure of antioxidant capacity. These results suggested that the addition of functional food ingredients (non-digestible maltodextrin and calcium lactate) did not affect the quality characteristics and antioxidant activity of black soybean Sunsik.

Dyslipidemia, defined as elevated triglyceride (TG), total- and LDL-C, and/or decreased HDL-C levels, is considered a principal risk factor for cardiovascular disease. The low-density lipoprotein receptor (LDLR) family has been considered a key player in the prevention of dyslipidemia. The LDLR family consists of cytoplasmic membrane proteins and plays an important role not only in ligand–receptor binding and uptake, but also in various cell signaling pathways. Emerging reports state that various functional ingredients dynamically modulate the function of the LDLR family. For instance, oats stimulated the LDLR function in vivo, resulting in decreased body weight and improved serum lipid profiles. The stimulation of LRP6 by functional ingredients in vitro activated the Wnt/β-catenin pathway, subsequently suppressing the intracellular TG via inhibition of SREBP1, PPARγ, and C/EBPα. Furthermore, the extract of Cistanchetubulosa enhanced the expression of the mRNA of VLDLR, followed by a reduction in the serum cholesterol level. In addition, fermented soy milk diminished TG and total cholesterol levels while increasing HDL-C levels via activation of LRP1. To summarize, modulating the function of the LDLR family by diverse functional ingredients may be a potent therapeutic remedy for the treatment of dyslipidemia and cardiovascular diseases.

추출방법에 따른 기능성 성분을 분석한 결과 양파 착즙액의 경우 100oC에서 열수 추출한 시료에서 총 phenol, flavonoid, quercetin의 함량이 가장 높게 검출되었으며, 에탄올 추출 시 100oC에서 추출한 시료와 거의 유사한 농도의 기능성 성분이 검출되었다. 양파 추출액의 quercetin 함량은 총 flavonoid의 80-90%로 quercetin이 flavonoid의 대부분을 구성하는 것으로 확인되었다. 양파분말의 경우 착즙액과 비교하여 추출된 flavonoid와 quercetin 함량이 약간 높았지만, thiosulfinate는 약 40% 낮은 농도를 나타내어 동결건조 과정이 황화합물의 손실을 초래하는 것으로 나타났다. 양파 껍질은 육질에 비하여 60배 이상 높은 quercetin을 함유하고 있는 것으로 나타났으나, thiosulfinate는 껍질에서 검출되지 않았다. 양파 추출액의 살균조건에 따른 기능성 성분을 분석한 결과 60, 80, 105, 121oC의 열처리는 살균 전과 비교하여 기능성 성분의 함량에 영향을 미치지 않았다. 양파 추출액의 저장동안 총 phenol, flavonoid, quercetin 함량은 저장기간과 온도에 상관없이 안정적으로 유지되었으나, thiosulfinate는 저장 기간이 길어질수록 감소하였고 25oC에 저장한 경우 4oC에서 보다 급격히 감소하는 경향을 나타냈다.

Aralia elata Seemann (AE) has long been used as a folk medicine for the treatment of various diseases including diabetes mellitus, anti-arthritic, and anti-gastric ulcer agent in Korea, Japan, and China. This study was performed to establish a simple and reliable HPLC/UV analytical method for determination of most active anti-hypertensive compound, a 3-O-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl hederagenin 28-O-β-D-xylopyranosyl(1→6)-β-D-glucopyranosylester (HE) for the standardization of the shoot extract of AE as a health functional food ingredient. The quantitative analytical method of HE was optimized by HPLC analysis using reverse-phase C18 column at 40°C with H2O and acetonitrile (70:30, v/v) as an isocratic mobile phase at a flow rate of 1.0 mL/min and detection wavelength of UV 205 nm. This HPLC/UV analytical method showed good specificity and high linearity in the tested range of 0.03125-2.0mg/ml with excellent coefficient of determination (R2) of 0.9999. The limit of detection and limit of quantification were 12.0 μg/mL and 36.5 μg/mL, respectively. Relative standard deviation (RSD) values of data from intra- and inter-day precision were less than 0.2% and 0.1%, respectively. These results indicate that the established HPLC/UV analytical method is very simple, specific, precise, accurate, and reproducible and thus can be useful for the quantitative analysis of HE as a functional anti-hypertensive compound in AE extract.
