Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document is Part 1 of GB/T 18525 "Irradiation Processes for Agricultural Products". GB/T 18525 has already published the following parts.

1.Legumes and their products;

2.Cereals and their products;

---Irradiation process for insect control and mold prevention in dried shiitake mushrooms (GB/T 18525.5);

6.Dehydrated Vegetables;

7.Spices and Seasonings;

8.Cooked Meat Products;

11.Dried Longan;

12.Pollen. This document replaces GB/T 18525.1-2001 "Irradiation Pesticide Process for Legumes". Compared with GB/T 18525.1-2001, the main differences are in the structural adjustments. Aside from 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) Added terms and definitions for "process dosage," "dosage non-uniformity," and "dosage distribution test" (see 3.4-3.6); changed "legumes" Terms and definitions for "and its products", "minimum effective dose", and "maximum tolerated dose" (see 3.1-3.3,.2001 edition 3.1-3.3);

c) The requirements for "irradiation facilities" have been changed (see Chapter 4,

5.1 of the.2001 edition);

1 Scope

GB/T 18525.1-2026 is the Chinese national standard covering the irradiation of beans and bean products - the dose that kills the insects that infest stored pulses without cooking the seed or spoiling its cooking quality. The standard fixes the dose range, the packaging and loading, the process control and dosimetry, and the records that make an irradiated lot traceable. It replaces GB/T 18525.1-2001 and takes effect on 1 December 2026, one of the twelve parts of the GB/T 18525 series revised together. It was issued on 25 May 2026 and takes effect on 1 December 2026, replacing GB/T 18525.1-2001. The document is under the responsibility of the Ministry of Agriculture and Rural Affairs. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

1.Scope This document specifies the irradiation equipment, pre-irradiation requirements, irradiation process, and post-irradiation treatment for insecticidal and bactericidal purposes involving legumes and their products. Record and file management. This document applies to irradiation treatment for insecticidal and sterilization of legumes and foods made from legumes through primary or deep processing. This document does not apply to legumes used for sprout production.

4 Irradiation device

4.1 Irradiation devices shall comply with relevant provisions such as 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 and the X-ray device that meets the relevant standards.

6 Irradiation process

6.1 Irradiation Operation According to the irradiation process documentation, the equipment operating parameters and loading mode were set, and the irradiation was organized. The irradiation device, related parameters, and online production were also monitored. The product circulation process is monitored and recorded.

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 Interruption Assessment If the irradiation process is interrupted, the impact on the absorbed dose of the product should be assessed, and the subsequent processing procedures should be recorded.

6.4 Repeated irradiation Legumes with low moisture content can be repeatedly irradiated to control pest infestation, but the cumulative dose should not exceed the tolerance dose of the legumes (see [reference needed]). 5.2.2).

7 Post-irradiation management

7.1 Storage Irradiated and unirradiated products should be stored separately. The storage environment should meet the temperature, humidity, and other conditions required by the product.
