Document Summary
Understand the concept of food irradiation as a food preservation method. Outline the terminologies commonly used in conjunction with preservation of food with ionizing energy. Describe the principles for determining the required irradiation dose depending on the desired outcome. Illustrate principles for determining wholesomeness and safety of irradiated foods. Summarize the regulations, and compare the magnitude of food products that are approved for irradiation in canada versus usa. Articulate personal values pertaining to use of ionizing energy in food preservation. Radiation (rays of energy): emission and propagation of energy through matter or space by electromagnetic disturbances. Food irradiation : application of radiation, as ionizing energy, to foods. Radiation is the energy , irradiation is the process ! Mw absorbed by food up to a death of 5-7. 5 cm. Food irradiation uses beta & gamma rays or electron accelerators. No significant heat produced: cold sterilization/pasteurization (old terminology) Division 26 of fda of canada: treatment of food with ionizing radiation .
