Scope

This standard applies to sodium selenite, a food nutritional fortifier obtained by preparing sodium selenite from selenious acid and sodium hydroxide, and then oxidizing sodium selenite with hydrogen peroxide.

Introduction

GB1903.56-2022 Standard Overview

GB1903.56-2022 is the national food safety standard of the People's Republic of China, which is specifically for the production, testing and application of the food nutrient fortifier sodium selenate. The standard was issued on June 30, 2022 and officially implemented on December 30, 2022.

Standard Formulation Background and Technology Evolution Analysis

With the development of the food industry, nutrient fortifiers are increasingly used in food. As an important nutrient fortifier, sodium selenate has the functions of antioxidant and immune enhancement. However, its production and use involve heavy metal detection and safety issues. The formulation of GB1903.56-2022 aims to ensure the quality and safety of sodium selenate and regulate its application in food.

Comparison table of standard frameworks

Dimensions	Old version of the standard (GB1903.56-201X)	New revised standard (GB1903.56-2022)
Scope of application	Applicable only to products with sodium selenite as raw material	Covering the entire production chain from selenious acid to finished products, adding hydrogen peroxide oxidation process requirements
Physical and chemical indicators	The specific methods for loss on drying and sodium selenite content are not specified	Detailed provisions are added in Appendix A to ensure the scientific nature of the detection method
Heavy metal restrictions	Indicators such as lead, arsenic, cadmium, and mercury have not been fully quantified	Specify the limit values of each heavy metal and require the use of ICP-OES method for detection

Implementation suggestions

To ensure the quality and safety of sodium selenate, it is recommended that:

• Manufacturers need to be equipped with professional testing equipment (such as ICP-OES spectrometers) and establish a quality control system.
• Strictly follow the limit requirements of GB1903.56-2022 when using food additives to avoid excessive addition.
• Strengthen employee training to ensure that operations comply with safety regulations (such as wearing protective equipment and properly disposing of waste).
