Technical Abstract: This chapter gives a comprehensive review on ionizing irradiation of fresh fruits and vegetables. Topics include principles of ionizing radiation, its effects on pathogenic and spoilage microorganisms, shelf-life, sensory quality, nutritional and phytochemical composition, as well as physiologic and enzymatic mechanisms of irradiation-induced changes. Radiation resistances of E. coli O157:H7, Salmonella spp. and Listeria spp., and radiation tolerances of various types of fresh and fresh-cut fruits and vegetables are tabulated. Toxicity and regulatory aspects of irradiation are briefly discussed.
