Abstract:Animal source foods are rich in proteins，essential amino acids，vitamins，and other nutrients.However，they are prone to infections by various pathogenic microorganisms because of their abundance of nutrients.Safe and efficient preservation methods are critical in ensuring food safety.Irradiation is a non-thermal processing technology widely used in the insecticidal treatment and sterilization of a variety of agricultural and food products.The irradiation dosage and types of irradiation rays substantially impact the quality and taste of the products.This article summarized γ -ray and electron beam，the two most widely used irradiation processing methods for animal source foods.The drawbacks in their current applications were also analyzed to provide theoretical references for the irradiation processing of animal source foods.
