Scope

This standard applies to the food nutritional enhancer sodium D-pantothenate obtained by the reaction of calcium pantothenate and sodium sulfate or by the condensation of sodium salt of dimethyl 7-dihydroxy-B,B-butyrate and B-alanine.

Introduction

GB 1903.32-2018 Standard Overview

This standard specifies the sensory requirements, physical and chemical indicators and test methods of sodium D-pantothenate as a food nutrient fortifier, and is applicable to products obtained by the reaction of calcium pantothenate and sodium sulfate or the condensation of sodium salt of β,γ-dimethyl butyrate and β-alanine.

Standard Framework Comparison

Dimensions	2018 Version Requirements	Comparative Analysis
Sensory Requirements	Color: white; Odor: slightly sour	Added a specific description of the crystal state, which is more stringent.
Physical and chemical indicators	Content of sodium D-pantothenate (%): ≥97.0; Specific rotation: 13.2-15.5	In line with international standards, the purity requirements have been raised.

Explanation of professional terms and application cases

High performance liquid chromatography (HPLC)

The method used to determine the content of sodium D-pantothenate ensures product quality through separation and detection technology.

LC columns can effectively separate the target compounds, and the UV detector (UV detector) can be used for qualitative and quantitative analysis.

Standard Formulation Background and Technological Evolution

As an important nutritional enhancer, the revision of the standard for sodium D-pantothenate reflects the strengthening of food safety supervision and technological progress. Compared with the old version of the standard, it is mainly optimized in terms of detection methods and physical and chemical indicators.

Implementation Suggestions

• Production link: strictly control the quality of raw materials to ensure that the synthesis process meets the requirements.
• Monitoring agency: use advanced technologies such as HPLC to conduct batch sampling.
• Regulatory measures: strengthen the inspection of imported products to prevent unqualified products from entering the market.
