Abstract:

In order to assess and evaluate beans with high antioxidant by measuring total antioxidant capacities and the hydroxyl radical scavenging activities of Adzuki Beans, studied 181 kinds of Adzuki beans from various area and various color. The result showed that, the color of surface, the weight of 100 beans and the beans, areas were the main factors of infecting Adzuki beans, antioxidant capability during analyzing. The green beans had the highest total antioxidant, yellow and white beans had the second, red beans had the lowest. The weight of 100 beans was in an inverse ratio of the antioxidant, if the weight of 100 beans was high, the antioxidant was low; compare total antioxidant capacities and the hydroxyl radical scavenging activities of 156 kinds of red beans, the kinds with the highest of total antioxidant capacity were from Liaoning which lies in northeast of China, and the lowest was from Japan, but the red beans from Japan had higher hydroxyl radical scavenging activities.
