Irradiation
• Cold pasteurization (no heat generated during irradiating)
• Using
• Radioactive isotopes (no “turned off”): 60Co, 137CS
• X‐rays
• Electron beam (can be “turned off” by pushing a power off button)
• Ultraviolet (UV) radiation
• Could not go through > 1 cm of transparency object equipment surfaces
• Radappertization
• Use of ionizing radiation (gamma radiation)
• To extend shelf life
• Sterilize meat, seafood, fruits & vegetables
• Kill microbes in moist foods (producing peroxides from water then peroxides oxidize cellular constituents)
