Abstract
In this study, we investigated the effects of irradiation on phytochemical content of soybean. Soybean seeds were irradiated at different doses of 0, 0.5, 1, and 2 kGy. In followings, the changes in isoflavone aglycone concentrations were analyzed. Also, the antioxidant potential was measured as DPPH free radical-scavenging activity. Genistein and daidzein concentrations, antioxidant activity and total phenolic and flavonoid content of soybean extracts were higher at the radiation dose of 0.5 kGy. Lower doses of irradiation improve concentration and antioxidant activity of soybean isoflavones as well as total flavonoid and phenolic content.
