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 12 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;

12.Pollen. This document replaces GB/T 18526.2-2001 "Pollen Irradiation Sterilization Process". Compared with GB/T 18526.2-2001, the only changes are structural adjustments. Aside from editorial changes, the main technical changes are as follows:

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

---Added the terms "bee pollen," "pine pollen," "process dosage," "dosage non-uniformity," and "dosage distribution test" and their definitions (see 3.2). 3.3, 3.6~3.8);

---The requirements for irradiation devices have been changed (see Chapter 4, Chapter 5 in the.2001 edition);

---The requirements for pre-irradiation moisture content and total bacterial count have been removed (see sections

4 Irradiation device

4.1 Available ionizing radiation sources include gamma rays produced by 60Co or 137Cs radionuclides, and electron accelerators producing energies not exceeding [a certain value]. The electron beam or energy limit of 10MeV complies with the relevant national regulations for X-rays.

4.2 The site selection, design, and construction of irradiation facilities shall comply with the relevant provisions of GB/T 17568 and GB/T 25306, and meet the requirements for food irradiation processing. Hygiene requirements.

4.3 Before product irradiation, the installation and operational qualification of the irradiation device should be completed. This should be in accordance with the requirements of GB 16334, GB/T 16841, and national standards. Relevant regulations are used to standardize processes and verify capabilities, and to create documented evidence.

6 Irradiation process

6.1 Irradiation Operation The product is loaded according to the process specification documents, the equipment operating parameters are set, irradiation is carried out, and the irradiation process is monitored and recorded.

6.2 Dose Monitoring According to the process specifications, deploy monitoring dosimeters, and perform dose measurements and record them. Dose measurements for gamma and electron beam irradiation devices should be performed separately. Do not follow the provisions of GB 16334 and GB/T 16841.The selection and calibration of the dosimetry system should be in accordance with the provisions of GB/T 16640. The decision will be made.

6.3 Interruption Assessment In the event of a processing interruption, the impact of the interruption on the absorbed dose of the product should be assessed, and the subsequent processing procedures should be documented.

7 Post-irradiation management

7.1 Storage Irradiated and unirradiated pollen should be stored separately. The storage area should be cool, dry, clean, and hygienic, protected from high temperatures, wind, rain, and contamination. Source of contamination.

7.2 Release The product can only be released after the monitoring results of the absorbed dose of the product confirm that the dose requirements of the irradiation process are met and there are no other abnormalities in the irradiation process. When there are cases where the dosage does not meet the process requirements or other non-conforming situations occur, the product should be treated as a non-conforming product.

7.3 Transportation During pollen transportation, high temperatures should be avoided, and it should be protected from direct sunlight, rain, and moisture. It should not be packaged with toxic, harmful, odorous, or easily contaminated items. Mixed transport.

8.Record and File Management All documents and records should be properly kept and available for inspection within the product's shelf life, and should be retained for at least 2 years.

12 Pollen

1.Scope This document specifies the irradiation equipment, pre-irradiation requirements, irradiation process, post-irradiation management, record keeping, and document management for pollen irradiation sterilization. Require. This document applies to the irradiation sterilization of bee pollen and pine pollen products intended to extend their shelf life.
