This study was carried out to determine the effect of moderate gamma (γ)-irradiation (3–20 kGy) on the characteristics and anti-inflammatory activity of water extracts (SFWEs). The SFWEs were γ-irradiated with 3, 7, 10, and 20 kGy absorbed doses, and their pH, color value, reducing sugar content, and viscosity were measured. The reducing sugar content showed a 1.89-fold increase at 20 kGy compared
