초록
This study investigated the reduction of microbial population and sensory propertiesin red pepper powders irradiated by gamma ray, electron beam, and X-ray. Populations of totalaerobic bacteria and yeast & molds in red pepper powders were decreased by irradiation treatmentin a dose-dependent manner. Gamma ray, electron beam, and X-ray at doses above 8 kGy caused100% inhibition on growth of aerobic bacteria in red pepper powders. Inhibitory activity of X-rayon sterilization of red pepper powders was significantly equal to or higher compared to gammaray and electron beam. Color and off flavor in red pepper powders were no significant differenceamong the control and samples irradiated with gamma ray, electron beam, and X-ray. As a result,the gamma ray, electron beam, and X-ray irradiation can be used to sterilize the microbial growthin red pepper powders without quality loss.
