Extending the shelf life of foodstuffs by irradiation

Gamma rays are used for irradiating foodstuffs, for instance, to kill insects and to destroy harmful microbes. Irradiation of food requires careful consideration. In Finland there is a facility capable of commercial irradiation of foodstuffs. But, however, the Finnish legislation only permits the irradiation of dried spices. Foodstuffs are irradiated commercially in about 50 facilities in 26 countries. Irradiation is mainly used for dried spices, crustaceans and certain vegetables and fruit. (2 figs.)
