This study examined the structural, physicochemical, and functional characteristics of five black soybean (Glycine max (L.) Merr.) cultivars—Cheongja5, Danheuk, Socheongja, Seum, and Soriheuk—bred and cultivated in Korea. We conducted comprehensive analyses on morphology, microstructure, thermal and hydration properties, pasting behavior, and antioxidant activity to identify cultivar-specific differences in processing suitability and functional properties. The results indicated significant varietal variations in seed coat ratio, cotyledon density, and color, which affected thermal stability, hydration, and viscosity development during heating. Cultivars with compact cotyledon matrices, such as Cheongja5 and Danheuk, displayed high enthalpy (ΔH), low solubility, and limited viscosity development, suggesting high structural stability and low thermal reactivity-traits favorable for thermally stable or beverage-type applications. In contrast, cultivars with looser structures and greater surface exposure, like Seum and Socheongja, exhibited higher swelling power, dispersion stability, and RVA viscosities, indicating their suitability for viscous or semi-solid systems. Notably, Soriheuk showed the highest antioxidant activity and levels of phenolic and flavonoid compounds, correlating with its high seed coat ratio and dark pigmentation, positioning it as a promising functional ingredient. These findings underscore that the physicochemical and structural diversity among black soybean cultivars significantly influences their processing performance and functional potential, providing a scientific foundation for selecting and developing functional cultivars.

The purpose of this study was to analyze the physicochemical properties by mixing ratio of soybean and peanut protein to secure basic data for developing alternative protein foods. As a result of analyzing the protein molecular weight pattern, it was confirmed that the specific molecular weight was affected by the soybean and peanut protein mixture. The content of glutamic acid, aspartic acid, arginine, glycine, serine, alanine, and tyrosine among nonessential amino acids was higher as the mixing ratio of peanut protein to soy protein was higher. However, the higher the peanut protein mixing ratio, the lower the water absorption capacity. Based on the results of this study, further studies, such as selecting soybean and peanut cultivars for determining the optimal mixing ratio of soybean and peanut protein and processing methods to improve physical properties, are necessary

본 연구는 도로 노면결빙 판정 알고리즘에 대해 알고리즘을 개선하고 실제 현장 측정 자료와 알고리즘 예측값을 비교하였을 때 알고리즘에 대한 적중률을 분석하였다. 분석을 위하여 포천시 신북면 금 동리의 도로 및 기상을 측정하였다. 알고리즘은 기존 도로 결빙 알고리즘을 선정하여 실제 결빙 조건 및 측정 수치에 맞춰 4차 알고리즘까지 개선하였다. 최종적으로 응결에 의한 결빙, 강수에 의한 결빙, 적설에 의한 결빙, 결빙상태의 지속, 풍속에 의한 결빙 5개의 알고리즘을 제작하였다. 포천 현장에서 알고리즘을 활용하여 예측할 경우 경우 결빙 적중률이 93.22%까지 개선되었다. 결빙 알고리즘에 대한 조합 비율에 대 해 도출하였을 때 응결에 의한 결빙과 결빙상태의 지속에 대한 알고리즘이 96%를 차지하였다.

The purpose of this study was to investigate antioxidant characteristics and anti-adipogenic effects of colored rice and brown rice extracts in 3T3-L1 adipocyte depending on cultivar (Josaengheugchal, Heugjinmi, Hongjinju, Geongganghongmi, Seolgaeng, Milyang 320, Sindongjin, Baegjinju). Colored rice and brown rice was extracted with 100% ethanol, followed by the analysis of polyphenol, flavonoid, anthocyanin, antioxidant, and anti-adipogenic activity. Total polyphenol and flavonoid content ranged from 6.86~314.08 mg GAE/g and 1.47~56.88 mg CE/g the highest total polyphenol and flavonoid content was observed in Heugjinmi cultivar. Anthocyanin composition was analyzed by HPLC, cyanidin-3-gluoside and peonidin-3-glucoside was found in black rice including Josaengheugchal and Heugjinmi. Also, the ABTS and DPPH radical scavenging activity of colored rice cultivars was higher than that of brown rice cultivars, the highest ABTS radical scavenging activity also was observed in Heugjinmi (128.20 mg TE/g). The anti-adipogenic effects of colored rice and brown rice extracts on differentiation of 3T3-L1 preadipocytes evaluated that extracts of Heugjinmi cultivar significantly reduced intracellular lipid accumulation. These results provide valuable information for the use of Korean colored rice cultivar as a functional food materials relative to anti-obesity.
