What is it about?
While food borne pathogens constitute a major public health problem world-wide, food post-harvest losses is considered to be the leading cause of hunger and malnutrition globally. Food irradiation is a process of preserving food in which food are exposed to appropriate doses of ionizing radiation in order to kill insects, molds and other potentially harmful microbes and allergens. The process involves carefully exposing food to a measured amount of ionizing radiation in a special processing room on a conveyor belt for a specifed duration. The radiation sources could be gamma ray, electron beam or X-ray. The radiation doses could be high, low or medium depending on the products to be irradiated and the target organism to be eradicated. Irradiation technology has various applications including sprout inhibition in root and tubers, disinfestation in cereals and pulses, reduction or elimination of food borne pathogens in vegetables and animal products and delayed ripening of fruits. All these applications are intended to increase shelf life and eliminate food allegenicity. Despite consumer concern on the safety and quality of irradiated foods, it is gradually gaining acceptance due to increased awareness and the perceived safety and quality as symbolized by the Radura symbol. With the increasing acceptance and commercialization of food irradiation, it could play an important role in solving the problems of food insecurity and food borne illnesses in the world.
