Enhancement of Antioxidant and Isoflavones Concentration in Gamma Irradiated Soybean

Table 1

Effect of different doses of gamma irradiation on isoflavone (genistein, daidzein, genistin, and daidzin), total phenol and tannin contents, DPPH RSC, and FRAP of soybean extracts.

Dose (kGy)Genistein (mg/kg)Daidzein (mg/kg)Genistin (mg/kg)Daidzin (mg/kg)TIC (mg/kg)TPC (mg kat./g)**TTC (mg kat./g)**DPPH RSC (%)**FRAP (FRAP units)**


Marked values are significantly different in comparison with nonirradiating control (Tukey test, ).
Data obtained from Štajner et al. [11].
TIC: total isoflavone content (sum of all 4 isoflavones); TPC: total phenol content; kat: katechine; TTC: total tannin content; DPPH RSC: DPPH radical scavenging capacity; FRAP: ferric reducing antioxidant capacity.
