Introduction

GB 1903.57-2022 Standard Overview

This standard specifies the quality requirements, test methods and application specifications for manganese citrate as a food nutrient enhancer, and is applicable to products prepared with citric acid and manganese sulfate or manganese carbonate as the main raw materials.

Item	Requirement	Test method
Manganese citrate content	96.5-104.8% (dry basis)	4.5 in Appendix A
Loss on drying	23.0-26.0% (decahydrate)	5.2 in Appendix A

Analysis of standard formulation background and technological evolution

With the development of food industry, nutritional fortifiers play an important role in improving the nutritional value of food. As an important ingredient for improving trace elements in food, the formulation of manganese citrate quality standards is of great significance to ensuring food safety and consumer health.

Practical application case: How to determine the content of manganese citrate

When detecting the content of manganese citrate, the EDTA titration method is an efficient and accurate method. By controlling the pH value of the solution and using appropriate indicators, its content can be accurately determined to ensure that the product meets national standards.

Implementation recommendations

1. Production companies should strictly follow the standards for raw material procurement and production process control.
2. The inspection department needs to be equipped with advanced testing equipment and calibrate it regularly to ensure data accuracy.
3. It is recommended to strengthen employee training to improve the understanding and implementation of standards.
