This standard replaces GB/T 18524-2001 “General technical requirements for
food irradiation”.
As compared with GB/T 18524-2001, the main changes of this standard are as
- CHANGE the standard name into “National food safety standard –
Hygienic specification for food irradiation processing”;
- MODIFY the standard structure;
- ADD the terms and definitions;
- ADD the basic hygienic requirements and management guidelines for
radiation processing, personnel and records;
- ADD the relevant requirements for the radiation processing process control
and radiation safety control;
- ADD the management requirements for records and documents;
- DELETE the Appendix A from the original standard, the content of which is
moved into the irradiation processing control part. DELETE the Appendix B
from the original standard which relates to the packaging materials, the
content of which is moved into the packaging part.
National food safety standard – Hygienic
specification for food irradiation processing
1 Scope
This standard specifies the basic hygienic requirements and management
guidelines for irradiation device, irradiation processing, personnel and records
for food irradiation processing.
This standard applies to food irradiation processing.
2 Terms and definitions
The terms and definitions in GB 14881-2013 apply to this standard.
2.1 Food irradiation
It refers to the irradiation process in which the radiation chemistry and radiation
microbiological effects produced by ionizing radiation in foodstuffs are used to
inhibit the germination, delay or promote ripening, and realize the insecticide,
disinfection, sterilization, and antisepsis.
2.2 Absorption dosage D
It refers to the quotient obtained through dividing the average energy which
is given by any ionizing radiation onto the substance having a mass of dm by
the dm, that is, , in the unit of J • kg-1 (joules/kg), in the name Gray,
and in the symbol of Gy, 1 Gy = 1 J • kg-1.
2.3 Dosage nonuniformity
The ratio of the maximum absorption dosage to the minimum absorption
dosage within the processing load.
2.4 Minimum effective dosage
The minimum dosage required to achieve a radiation purpose, i.e., the lower
limit of the process dosage, when the food is irradiated.
2.5 Maximum tolerated dosage
The maximum dosage, i.e., the upper limit of the process dosage, that does
not adversely affect the food quality and functional characteristics when the
food is irradiated.
2.6 Irradiation dosage After the food loading mode is established, it shall load with the actual
product or the simulant of similar density to measure its dosage distribution, so
as to perform the loading mode verification. When measuring the dosage distribution, a sufficient number of
dosimeters shall be placed in the irradiated product load to determine the
minimum and maximum dosage areas, then select the conventional dosage
monitoring location, AND calculate the relationship between the dosage at the
conventional dosage point and the maximum dosage and minimum dosage.
The dosage measurement shall include the sampling monitoring product
absorption dosage, product dosage nonuniformity verification, and the
inspection of the relationship between the device operation parameters and
product absorption dosage. In conventional irradiation processing, the dosimeter shall be placed at
the location of the minimum dosage in the irradiation container OR the position
easy to be placed having the known quantitative relationship with the minimum
dosage. Meanwhile, it shall also install a dosimeter at the maximum dosage
area to monitor the maximum acceptable dosage of the food. AND it shall
make record AND archive it. When the irradiation parameters change, the dosage distribution shall
be re-measured. It shall, in accordance with the expected irradiation
processing application of the device, the dosage measurement system
performance, and the measurement uncertainty, etc., select the appropriate
dosage measurement dosimeter in accordance with the provisions of GB/T
16640, AND it shall trace back to the national absorption dosage standards.
5.2.5 Repeated Irradiation In addition to the repeated irradiations of the low moisture foods (such
as cereals, beans, dehydrated food, and similar products), the repeated
irradiation shall not be performed under other conditions. Irradiation of the following foods is not considered as repeated
- Food made from raw materials irradiated by less than 1 kGy dosage;
- Food containing 5% or less of radiation;
- Food irradiated for many times by all the dosage to be absorbed to realize
the special process purposes. The cumulative dose of repeated irradiated food shall not exceed 10
5.3 Post-irradiation treatment
5.3.1 Storage
8 Marking
The marking of irradiated food shall comply with the requirements of clause of GB 14891 and GB 7718.
9 Records and document management
9.1 Irradiation records
9.1.1 Irradiation device records
It shall record all data relating to the construction, acceptance, licensing
registration, and maintenance of the irradiation device.
9.1.2 Recording of irradiation processing parameters
It shall record the parameters on the irradiation processing control, dosage
detection, and irradiation device during startup and daily operation.
9.1.3 Irradiation product records
It shall record the product type, irradiation purpose, irradiation dosage,
irradiation date, and post-irradiation product quality inspection (including
post-irradiation sampling, retention and inventory management).
It shall record the irradiation processing requirements and conditions, which
shall be kept by special person AND archived for reference. The records of the
irradiation processing and conditions shall include but not limited to the
a) The name, code, lot number and quantity, exit-factory date, receiving
date of the irradiated food, AND the name, address and contact of the
irradiated food delegator;
b) The purpose of irradiation;
c) The name and activity of the radionuclide, OR the irradiation device
energy, beam, scan width, transmission speed and processing
parameters that affect the absorption dosage of the food;
d) The density of the irradiated food, AND the loading pattern of the food in
the irradiation container or within the irradiation device;
e) Irradiation dosage;
f) The operating parameters set by the irradiation device;
g) The date of irradiation;
h) The placement and number of conventional dosimeters;
