The change of quality characteristics and antioxidant properties of black soybean flours after germination and roasting treatment were evaluated. The moisture content of roasted black soybean flours decreased significantly according to roasting temperatures and times, and the crude ash, protein, and fat contents increased. The water binding capacity of roasted black soybean flours with and without germination increased significantly according to roasting temperatures and times; however, water solubility index and swelling power decreased. The lightness of roasted black soybean flours was significantly decreased, and the redness and yellowness increased. The phenolic compounds and radical scavenging activity of roasted black soybean flours increased with increasing roasting temperatures and times. The total polyphenol contents of roasted black soybean flours with and without germination were 5.43-7.81 and 4.52-6.17 mg GAE/g, and total flavonoid contents were 2.90-3.50 and 2.34-3.01 mg CE/g, respectively. The DPPH radical scavenging activity of roasted black soybean flours, with and without germination, was 254.98-415.05 and 171.95-295.15 mg TE/100 g, and the ABTS radical scavenging activity was 459.74-596.37 and 422.95-526.85 mg TE/100 g, respectively. As a result, it is necessary to establish quality standards for each application by considering the quality characteristics and antioxidant properties of roasted black soybean flours.
