Definitions
- ABSTRACT F i A mm The material to be irradiated is placed with an oxygen binding [30] m n y medium into a gas-tight package and irradiated.
- Oxygen particularly in one of the aforementioned highly reactive forms, can give rise to a wide variety of harmful effects depending on the nature of the packaged material or of the packaging material itself. In the first place, there is oxidation of the packaged material itself, also foodstuffs and other consumables containing fats and albumen for example fish and meat products can be adversely affected.
- any oxygen that may be present may unfavorably continue the ripening process of fruit, for example strawberries, which-have been exposed to a preserving irradiation, thus impairing the visual condition and taste of the packaged material.
- fruit for example strawberries
- a preserving irradiation thus impairing the visual condition and taste of the packaged material.
- a correspondingly increased radiation dose or duration of radiation or radiation intensity also increases the danger of harmful oxidation of the packaged material in conjunction with the formation of ozones or nascent oxygen.
- Oxygen in an irradiated package for foodstuffs and other consumables may also have an adverse effect on aromatic substances.
- the invention provides a method and a package which preserves materials such as foodstufi's, consumables, pharmaceuticals, and the like over long time periods without adverse effects from entrapped oxygen in the package upon the-package being subjected to radiation and the like.
- the method resides in the steps of packaging the material to be irradiated in a gas-tight covering along with a medium capable of binding oxygen and of exposing the sealed material to an ionizing irradiation. During the time of irradiation, as well as thereafter, any gases in the interior of the covering come into contact with the oxygen binding medium and become bound.
- the oxygen can be bound either chemically or physically.
- adsorption media are particularly suitable for physical binding.
- media such as silica gel which is particularly activated as regards its oxygen binding capacity by ionizing radiation can be used. With such characteristics, it is in some cases possible to dispense with special measures which protect the oxygen binding medium against premature contact with atmospheric oxygen while the package is not yet sealed.
- the oxygen binding medium in small, particulate or porous form, both for chemical as well as for physical binding as the increased surface area obtained by this measure accelerates and intensifies the binding process.
- the package of the invention includes the material to be irradiated, the oxygen binding medium and a gas-tight covering enclosing the material and medium therein in sealed relation.
- the interior of the gas-tight covering is constructed as a support for the oxygen binding medium.
- the oxygen binding medium is appropriately disposed within its own gas-permeable covering or sheath such as a perforated cartridge. This separates the medium from the packaged material thus preventing undesirable contact between the binding medium and the material. It is furthermore recommended that the gas-permeable covering for the oxygen binding material be joined to the gas-impermeable covering for the material to be irradiated. The binding medium and the packaged material is then automatically separated when the package is opened.
- the oxygen binding medium may be disposed in a gas-permeable foil which is coated onto the gas-tight covering enclosing the material to be irradiated.
- a gas-permeable foil is advantageously constructed of polyethylene while the use of packaging material having aluminum foil is recommended for the gas-tight covering.
- Aluminum has a relatively high transmittance for the ionizing radiation, readily reflects incident heat radiation and is very suitable as hygienic packaging material.
- the oxygen binding media can, in another embodiment, be brought into contact with the oxygen only after sealing of the package for the material to be irradiated. This may be achieved by disposing the oxygen binding medium in a gasimperrneable covering which is opened only after sealing of the gas-tight covering for the material to be irradiated.
- the material for the packages of the kind heretofore described can be easily prefabricated and provided it is protected by a suitable hermetically sealed packaging against premature exhaustion of the binding capacity can be stored or transported to the location of use for any desired period of time.
- the gaseous oxygen disposed in the package is bound and thus does not cause any harmful oxidation of the irradiated material or any of the other detrimental effects.
- the radiation dose it is possible for the radiation dose to be substantially increased without having to anticipate any increased oxidation of the irradiated material.
- FIG. 1 illustrates a sealed package prepared for irradiation with an enclosed cartridge containing oxygen binding media according to the invention
- FIG. 2 illustrates an enlarged view of the cartridge of FIG. 1
- FIG. 3 illustrates an embodiment of the invention in which the oxygen binding medium is disposed in a gas-permeable covering joined to the interior of a packaging material;
- FIG. 4 illustrates a gas-permeable foil in which the oxygen binding medium is disposed according to the invention
- FIG. 5 illustrates an embodiment according to the invention in which the oxygen binding medium is disposed in a gas-impermeable covering which is opened only after the gas-tight covering for the material to be irradiated is closed.
- the package 11 consists of a material which is as far as possible impermeable to gas, for example, a paper-like packaging material with an inlaid aluminum foil and a plastic coating on the interior.
- the package 1 1 contains a material 12, for example fresh meat, and is hermetically sealed by means of a welding seal 13 so that the material 12 is enclosed in a substantially gas-tight package.
- a cartridge 14 of oxygen binding medium is also enclosed within the interior of the package 1 1.
- the cartridge 14 comprises a cylinder 15, forming a gas-permeable covering which is closed at the endfaces by means of lids 16.
- the interior of the cartridge 14 contains the oxygen binding medium for example, in the form of granular material 17 which is in physical contact with the gases in the interior of the package covering by means of apertures 18 in the wall of the cylinder 15.
- the material 12 in the package 11 can be exposed to an ionizing radiation as is known. During such a time, and thereafter, any oxygen in the package interior is, at least, partially bound by the medium 17.
- the package can also be formed of a foil-like packaging material 21 which forms the gas-tight covering for the material to be irradiated.
- the material 21 may be formed of a plastic foil which can also be lined in any desired manner withpaper or metal foil.
- This package also includes a tubular chamber 22 on the material side which forms the interior of the package.
- This tubular chamber 22 is joined by means of flanges 23 to the foil 21, namely by welds 24 and, prior to welding, is filled with a granular medium 25 capable of binding oxygen.
- the medium 25 comes into physical contact with the oxygen in the package through apertures-26 in the chamber wall.
- any oxygen .which is entrapped in a package constructed of the material described hereinabove (FIG. 3)' is bound by the medium 25.
- the packaged material is removed from the gas-tight covering 21, automatic provision is made to ensure that the covering 21 and the packaged material are separated from each other.
- the oxygen binding medium 31 can also be incorporated into a gas-permeable foil 32 so that strips of the foil 32 can be used in the formation of packages.
- the oxygen binding medium 31 in a pulverized or granular form is disposed in a gas-permeable foil 32 of polyethylene.
- the foil 32 is appropriately obtained in such a manner that the small, particulate binding medium is admixed to the polyethylene during extrusion.
- suitable selection of the particle size and the degree of admixture preferably 0.5 to
- a foil-like material 33 for the gas-tight impermeable covering of a package is then coated with the foil 32.
- the oxygen binding medium can also be stored within gas-impermeable coverings which are opened only after the covered medium has been sealed into a package.
- the oxygen binding medium 44 in small particulate form is filled in a container 41 made of fragile gas-impermeable material such as a thin glass.
- the container 41 in turn is placed within a small gas-permeable material such as a small textile bag 43 which is closed by means of a clip 42.
- the small bag 43 with the container 41 is then enclosed in the package in place of the cartridge 14 shown in FIG. 1.
- the thin wall of the container 41 is broken from the exterior by applying pressure or a blow.
- the medium 44 thus comes into contact with the oxygen which diffuses through the wall of the small bag 43. In this way, it is possible to control the timing of the beginning of oxygen binding by the medium 44.
- the protective container is appropriately destroyed immediately after the package is sealed.
- Media suitable for binding oxygen include those capable of binding oxygen chemically as well as those capable of inducing binding by physical means. All readily oxidizing inorganic material are particularly suitable as chemically acting media. Metals such as manganese, aluminum and magnesium in small particulate form are particularly suitable although it is recommended that the media be stored in a protective atmosphere, for. example nitrogen, in the interior of a container according to FIG. 5 as a protection against premature oxidation. However, organic compounds with a suitable binding activity relative to oxygen are also feasible.
- silica gel having a particle size of for example 0.0l to 5 mm is very suitable for physical binding of the oxygen.
- Silica gel is characterized by the surprising property that is adsorption capacity relative to oxygen is substantially increased by irradiation with ionizing rays by virtue of a structural change resulting from the irradiation. Furthermore, it is absolutely non-toxic and acts practically without thermal effects.
- Another medium for physical binding of oxygen is bentonit'e. 1 v I
- an increase of the surface .area of the oxygen binding medium is recommended by using the medium in small particulate form such that the ratioes of surface area to volume of the particulate are relatively large. It would however also be possible to employ the oxygen binding medium in the form of a porous or spongy member.
- the package In order to treat the packaged material, the package should be made as impermeable to gas as is possible. In practice, however, a certain exchange of gas is possible under some circumstances even with lined packaging material having a plastics coating and a metal foil insert.
- the gas-impermeable property of the covering for the material to be irradiated is therefore meant to imply impermeability to gas as obtainable under practical conditions. Further, in order to improve the impermeability of aluminum foil it is advisable to apply a lacquer coating on the foil web, at least on one side.
- a package comprising a material to be irradiated; a gas-tight covering enclosing said material in sealed relation; and
- amedium within said covering capable of binding oxygen
- said medium having a surface area exposed to the interior of said covering and having an oxygen binding capacity which increases upon irradiation.
- a package as set forth in claim 1 which further comprises a foil coating the interior of said covering and wherein said medium is disposed in said foil.
- a package as set forth in claim 1 which further comprises a gas permeable covering about said medium within said gastight covering.
- a package as set forth in claim 1 which further comprises a gas impermeable covering about said medium within said gas-tight covering; said gas impermeable covering being adapted to be opened within said gas-tight covering to com- 5 municate said medium with said material.
