Introduction

GB 1903.24-2016 Standard Overview

GB 1903.24-2016 "National Food Safety Standard Food Nutrition Fortifier Magnesium Vitamin C Phosphate" is a mandatory standard jointly issued by the National Health and Family Planning Commission of the People's Republic of China and the State Food and Drug Administration, and has been implemented since June 23, 2017. This standard specifies the chemical name, molecular formula, structural formula, relative molecular mass and technical requirements of magnesium vitamin C phosphate, providing an important basis for the quality control of food nutrition fortifiers.

Chemical properties of magnesium ascorbic acid phosphate

Project	Content
Chemical name	Magnesium L-ascorbic acid-2-phosphate
Molecular formula	C5H7PO4Mg·10H2O
Relative molecular mass	759.22

Technical requirements and inspection methods

The technical indicators of magnesium ascorbyl phosphate include: water content, pH, specific optical rotation, free phosphoric acid acidity, oxide and heavy metal content, etc. The standard specifies the testing methods for these indicators, among which key parameters such as magnesium ascorbyl phosphate content are determined by high performance liquid chromatography and ultraviolet spectrophotometry.

Item	Indicator	Test method
Ascorbic acid magnesium phosphate content	≥95.0%	Appendix A A.3
pH value	7.0-8.5	GB/T 9724

Significance of the implementation of the standard

Ascorbic acid magnesium phosphate is an important food nutrient fortifier, widely used in beverages, dairy products and other fields. The promulgation and implementation of GB 1903.24-2016 provides a scientific basis for ensuring the quality and safety of its products.
