3、n treating driedspices, herbs, and vegetable seasonings to control pathogens and spoilage microorganisms. Informa-tion on handling these commodities before and after irradiation is also provided.This guide should be followed when using irradiation technology where approved by an appropriateregulator

4、y authority. It is not to be construed as a requirement for the use of irradiation, or as a rigidcode of practice. While the use of irradiation involves certain essential requirements to attain theobjectives of the treatment, some parameters can be varied in optimizing the process.This guide has bee

Generally, these items have moisture content of 4.5 to12 % and are available in whole, ground, chopped, or otherfinely divided forms, or

7、 as blends. The blends may containsodium chloride and minor amounts of dry food materialsordinarily used in such blends.1.2 This guide covers gamma, electron beam, andX-radiation treatment. This guide also covers low energyelectron beam treatment where only part of the product isirradiated (that is,

8、 surface treatment).1.3 This guide covers absorbed doses ranging from 3 to 30kilogray (kGy).NOTE 1U.S. regulations permit a maximum dose of 30 kGy. (See21CFR 179.26.) EU regulations permit a maximum dose of 10 kGy. (SeeDirective 1999/3/EC.)1.4 The values stated in SI units are to be regarded asstand

33、 for consumption.5. Pre-Irradiation Product Handling5.1 Upon receipt at the irradiation facility, inspect packagesand containers of the commodities according to relevant GoodManufacturing Practices (GMPs) to ensure that their integrityhas not been compromised. See for example 21 CFR 110.5.2 Radiatio

34、n can be applied to these commodities in bulk,in-line prior to packaging, or in commercial packages.5.3 Handling of the commodities in an irradiation facilityshould be in accordance with relevant and current GMPs.There are no special requirements for handling of the com-modities prior to irradiation

35、 except for providing controlmeasures to prevent post-irradiation re-contamination in stor-age facilities and for assuring separation of irradiated andnon-irradiated product.5.3.1 Product SeparationIt may not be possible to distin-guish irradiated from non-irradiated product by inspection. It isther

36、efore important that appropriate means, such as physicalbarriers, or clearly defined areas, be used to maintain non-irradiated product separate from irradiated product.6. Packaging and Product Loading Configuration6.1 Packaging:6.1.1 Packaging commodities prior to irradiation is onemeans of preventi

37、ng post-irradiation contamination.6.1.2 Use packaging materials suitable to the product con-sidering any planned processing (including irradiation) andconsistent with any regulatory requirements (see GuideF1640).6.2 Product Loading Configuration:6.2.1 The size, shape, and loading configuration of a

38、processload for the commodities to be irradiated should be determinedprimarily by considering design parameters of the irradiationfacility (see Practices ISO/ASTM 51608, ISO/ASTM 51649,ISO/ASTM 51702, and ISO/ASTM 51818). Critical irradiationparameters include the characteristics of product transpor

39、tsystems and of the radiation source as they relate to the dosedistribution obtained within the process load. These parametersand product dose specifications should be taken into account indetermining the size, shape, and loading configuration of aprocess load (7.3).7. Irradiation7.1 Standard Operat

40、ing Procedures (SOPs)Standard op-erating procedures for food irradiation are documented proce-dures that are used to ensure that the technologically estab-lished dose range and irradiation conditions selected by theradiation processor are achievable in a specific facility. Theprocedures should be es

41、tablished by qualified persons havingknowledge in irradiation requirements specific to the food andthe irradiation facility (21 CFR 179.25).7.1.1 Installation qualification, operational qualification,performance qualification and process control should be per-formed following the requirements of Pra

42、ctices ISO/ASTM51702, ISO/ASTM 51608, ISO/ASTM 51649,orISO/ASTM51818.7.2 Radiation SourcesThe sources of ionizing radiationthat may be employed in irradiating these commodities arelimited to the following (see CX/STAN 106-1983):7.2.1 Isotopic SourcesGamma rays from radionuclides60Co (1.17 and 1.33 M

43、eV) or137Cs (0.66 MeV) (see PracticeISO/ASTM 51702);7.2.2 Machine SourcesX-rays and accelerated electrons,(see Practices ISO/ASTM 51608, ISO/ASTM 51649, andISO/ASTM 51818).NOTE 3The Codex Alimentarius Commission, as well as regulationsin some countries, currently limits the maximum electron and X-ra

44、yenergies for the purpose of food irradiation (CX/STAN 106-1983).7.3 Absorbed DoseIrradiation specifications from the pro-cessor of the commodities should include minimum andmaximum absorbed dose limits and the volume of interestwhere these limits should be regarded (see 7.3.3): the lowestdose neces

45、sary to ensure the intended effect (for example,microbial load reduction, pathogen inactivation), and a highestdose that does not negatively affect the product quality toprevent product degradation. One or both of these limits maybe prescribed by government authorities for a given applica-tion. See

46、for example 21 CFR 179.26. It is necessary toconfigure irradiation parameters to ensure processing is carriedout within these limits in the volume of interest. Once thiscapability is established, it is necessary to monitor and recordabsorbed dose values during routine processing. (See 11.1.3.)NOTE 4

47、The minimum dose absorbed by a certain part of productvolume might be zero for some applications where a targeted location ofproduct needs to be treated. The volume of interest might be a thinexternal layer of the product if it has been demonstrated that microorgan-ism control is satisfactory.7.3.1

48、DosimetryDosimetry is a major component of atotal quality assurance program for adherence to good manu-facturing practices used in radiation processing of food. CX/STAN 106-1983 and CAC/RCP 1-1969 strongly emphasize therole of dosimetry for ensuring that irradiation is properlyperformed, since dosim

49、etry is part of a verification process forestablishing that the irradiation process is under control.7.3.2 Dosimetry SystemDosimetry used in thedevelopment, validation, and routine control of the irradiationprocess shall have measurement traceability to national orinternational standards and shall have a known level ofuncertainty. The selected dosimetry system should be appro-priate for the radiation source being used, the range ofabsorbed doses required, and the environmental conditions(e.g., product temperature, irradiation temperature) expected
