Irradiation is an important modern food processing technology.However,the safety of food irradiation has been concerned by consumers.Therefore,the study of food irradiation identification techniques is of great significance.Identification of irradiated foods is based on the characteristics of food-irradiation to the nature of the physical and chemical changes in measurements.This paper describes the irradiation of food chemical markers(e.g.fat degradation products,protein degradation products,free radical,DNA degradation products) and physical markers(e.g.energy) and its detection techniques.At the same time,the prospects of identification techniques for irradiated food were analyzed.
