Abstract

The goal of this study was to evaluate the quality characteristics of various beans in distribution. The quality characteristics investigated were proximate composition, color, free sugars, organic acids, amino acids, and minerals. Bean samples analyzed were white soybeans (Glycine max. (L.) Merrill), kidney beans (Phaseolus vulgaris var. humilis), black soybeans (Glycine max (L.) Merr.), black small soybeans (Rhynchosia nulubilis), sword beans (Canavalia gladiata), and green beans (Phaseolus vulgaris). The highest contents of crude fat and crude protein were 17.60${\pm}$0.14% for white soybeans, and 42.38${\pm}$0.15% for black soybeans, respectively. Higher color values compared to the other samples were $L^*$ (64.07${\pm}$0.97) for sword beans, $a^*$ (15.64${\pm}$0.48) for kidney beans, and $b^*$ (22.92${\pm}$0.09) for white soybeans. The highest contents of sucrose, oxalic acid, and malic acid in black small soybeans were 54.23 mg/g, 23.26 mg/100 g and 18.24 mg/100 g, respectively. Xylose, galactose, lactose, malonic acid, succinic acid, and lactic acid were not detected in the soybeans studied, whereas the glutamic acid content of soybeans ranged from 2.68 to 6.18 g/100 g. Levels of K and Mg contents in soybean were higher than those of the other minerals.

콩의 일반성분 분석에서 조지방은 백태 17.60${\pm}$0.14%, 조단백질은 서목태 42.38${\pm}$0.15%로 가장 높고, 조회분의 경우 비슷한 값을 나타내었다. 색도는 L값 작두콩 64.07${\pm}$0.97, a값 강낭콩 15.64${\pm}$0.48, b값 백태 22.92${\pm}$0.09로 각각 가장 높은값을 나타내었다. 유리당 중 fructose, glucose, maltose는 서목태가 각각 13.92 mg/g, 20.52 mg/g, 2.61 mg/g으로 가장 높은 함유량을 보였으며, sucrose는 서리태가 54.23 mg/g으로 가장 높은 함유량을 보였다. 유기산 중 oxalic acid, malic acid, tartaric acid는 각각 서목태가 23.26 mg/100 g, 18.24 mg/100g, 23.6 mg/100 g으로 가장 높은 함유량을 보였으며, citric acid의 경우 청태가 7.22 mg/100 g으로 가장 높은 함유량을 보였다. 콩의 종류에 따라 각각 함유 성분에 차이가 있었다. 구성아미노산은 glutamic acid가 2.68~6.18 g/100 g으로 가장 많이 함유하고 있으며, 그 중 서리태가 가장 많이 함유하고 있는 것으로 나타났다. 콩의 무기질은 K, Mg이 가장 많이 함유되어 있고, Co, Cu, Zn은 미량 함유되어 있는 것으로 나타났다. 이상의 결과에서 콩의 품종에 따른 차이와 동일한 품종일지라도 재배 및 환경 요인, 건조 방법, 건조 상태에 따라 많은 영향을 받는 것으로 생각된다.
