12.Pollen. This document supersedes GB/T 18525.3-2001 "Irradiation Pesticide Process for Jujubes" and GB/T 18525.4-2001 "Irradiation of Dried Goji Berries and Raisins". "Insecticide Application Process". This document is based on GB/T 18525.3-2001, and integrates the content of GB/T 18525.4-2001. Compared with GB/T 18525.3-2001, apart from structural adjustments and editorial changes, the main technical changes are as follows:

a) The scope has been changed (see Chapter 1, Chapter 1 of the.2001 edition);

b) The terms "dried fruit," "process dosage," "dosage non-uniformity," and "dosage distribution test" were added; the term "red dates" was deleted; and the procedure was modified. Definitions of "minimum effective dose" and "maximum tolerated dose" (see Chapter 3,.2001 edition);

c) The term "irradiation device" has been changed (see Chapter 4,

5.1 of the.2001 edition);

3 Dried Fruit

1.Scope This document specifies the requirements for irradiation equipment, pre-irradiation procedures, irradiation process, post-irradiation procedures, record keeping, and document management for dried fruit irradiation processing. This document applies to dried fruits made from fresh fruits (such as red dates, goji berries, grapes, etc.) through dehydration processes such as sun-drying and drying. Irradiation of fruits and food products for insect and bacteria control.

4 Irradiation device

4.1 Irradiation devices shall comply with the relevant provisions of GB/T 17568 and GB/T 25306.

4.2 The irradiation device shall be a gamma-ray device that produces 60Co or 137Cs radionuclides, or an accelerator with an electron beam energy not exceeding

10 MeV. The device is an X-ray device that meets the relevant standards.

6 Irradiation process

6.1 Irradiation Operation Irradiation processing is organized according to the requirements of the irradiation process documents. The process includes setting parameters, loading products, irradiation implementation, and dose monitoring. It also monitors and records the irradiation equipment, related parameters, and online product flow process.

6.2 Dose Monitoring According to the irradiation process documentation, monitoring dosimeters are deployed for measurement and recording. The dosimeter measurement system is selected according to GB/T 16640. Select and regularly trace back to the national absorbed dose standard.

6.3 Irradiation Interruption If the irradiation process is interrupted, its impact on the absorbed dose of the product should be assessed, and subsequent processing and recording should be carried out.

6.4 Repeated irradiation Dried fruits can be repeatedly irradiated to control pests. The cumulative dose should not exceed the maximum tolerable dose for the dried fruit.

7 Post-irradiation management

7.1 Storage Irradiated and unirradiated products should be stored separately. The storage environment should meet the requirements of 5.1.2.
