Technical Abstract: Ionizing irradiation is a non-thermal processing technology that can be used to improve microbial safety and reduce food loss. This chapter reviews the current status of food irradiation technology. Topics covered include comparison of three types of radiation (gamma ray, electron beam and X-ray) in terms of advantages and disadvantages, dose unit and dosimetry, irradiation facilities, optimization to achieve desirable benefits, interaction of radiation with food components, mechanisms for microbial inactivation, factors affecting irradiation efficacy of inactivating human pathogens, impact on product quality, and labeling and consumer acceptance of irradiated foods.
