Food processing

Food Irradiation is a physical treatment in which food is exposed to calculated dose of ionizing radiation. Electron beam processing may be used for the following purposes: reduce the incidence of foodborne disease by destroying pathogenic organisms; important  decrease in product loss due to insects, bacteria and mold; extended shelf life and reduce loss of foodstuffs by premature ripening, germination, or sprouting;  reducing the dependence on chemical pesticides
