Introduction

1. Standard Overview

Inositol (cyclohexanehexol) is an important food nutrient enhancer. This standard (GB1903.42-2020) specifies its sensory requirements, physical and chemical indicators and test methods to ensure its safety and effectiveness.

2. Comparison of standard frameworks

Standard dimensions	GB1903.42-2020	International standard (reference)	Difference analysis
Scope of application	Inositol generated by hydrolysis of calcium phytate scale	Widely used in food fortification	Domestic standards are more specific
Physical and chemical indicators	Inositol content ≥97.0%	≥98.0% (international average)	Domestic requirements are lower
Test methods	Gravimetric method, high performance liquid chromatography	Isotope detection method (some countries)	Method complementarity

3. Implementation suggestions

Manufacturers: Strictly follow the standards for raw material procurement and production to ensure that the products meet various indicators.

Inspection agencies: Establish a complete testing system and give priority to high performance liquid chromatography to improve accuracy.

Regulatory authorities: Strengthen daily supervision, focusing on checking the implementation of physical and chemical indicators and inspection methods.
