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.
