Abstract

For increasing the shelf life of foods having a rind, skin, shell or like partially protective covering, decay-causing organisms are inactivated in only a small fraction of the food including all the exterior surface by bombardment with penetrating ionizing radiation such as high velocity electrons. The food may before such bombardment be enclosed in a film which is impervious to the passage of micro-organisms but pervious to the radiation, e.g. oranges may be sealed in plastic sacks or may be lacquered. Energy levels of 500,000-1,000,000 electron volts, and electron doses of 50,000-700,000 rep (1 rep is the equivalent of 100 erg./g.), preferably administered at 20,000 rep/sec., are referred to. Specification 657,295 is referred to.ALSO:For increasing the shelf life of foods having a rind, skin, shell, or like partially protective covering, exemplified by most fruits, vegetables and fish, eggs, nuts, seeds, and animal carcasses, decay-causing organisms are inactivated in only a small fraction of the food including all the exterior surface by bombardment with penetrating ionizing radiation such as high velocity electrons produced by a cyclotron. The food may before such bombardment be enclosed in a film which is impervious to the passage of microorganisms but pervious to the radiation, e.g., oranges may be sealed in plastic sacks or may be lacquered. Energy levels of 500,000-1,000,000 electron volts, and electron doses of 50,000-700,000 rep (1 rep is the equivalent of 100 erg/g.), preferably administered at 20,000 rep/sec., are referred to. Specification 657,295, [Group III], is referred to.
