Two varieties of adzuki beans (Vigna angularis), Bloodwood and Erimo, were stored at temperatures of 10, 20 or 30 °C, and relative humidities (RH) 40 or 65%, and samples were analysed at 0, 1.5, 3 and 6 months. Storage at 30 °C for > 1.5 months caused a significant decrease in the a* and b* colour values and darkening of the seed coat. Beans stored at 65% RH had lower L* but higher a* and b* colour values than those stored at 40% RH. Bloodwood and Erimo samples showed similar trends in colour during storage. The best storage conditions for the preservation of the adzuki colour were 10 °C and 65% RH. The Australian beans had lower L*, a* and b* colour values than Japanese Erimo-shouzu beans and storage increased the difference.
