Introduction

GB1886.256-2024 Standard Overview

GB1886.256-2024 "National Food Safety Standard Food Additive Methyl Cellulose" was issued on February 8, 2024 and officially implemented on August 8. This standard replaces the old version GB1886.256-2016, and makes important revisions to the following aspects:

• Modify the relative molecular mass range
• Optimize the reagent expression in the identification test
• Update the viscosity test method

Standard Framework Comparison Table

Old version requirements	New version requirements	Modification instructions
Relative molecular mass: not clearly specified	Structural units with a degree of substitution of 1.45: 182.46 (according to the 2018 international relative atomic mass)	Add specific numerical requirements
Viscosity test method	Test according to the marked viscosity range in grades, with accuracy increased to 1%	Optimize experimental steps
Reagent description	Use standardized chemical names and solution preparation methods	Unify reagent specifications

Technical requirements interpretation

Sensory requirements:Methyl cellulose should be white or nearly white powder or granules, which can be detected by visual and tactile methods.

Physical and chemical indicators:Including key parameters such as methoxyl content, viscosity and drying loss. Among them, the methoxyl content is determined by gas chromatography, accurate to two decimal places.

Actual application case

A food additive manufacturer needs to complete equipment upgrades and test method optimization before the implementation of the new version of the standard. By introducing the Brookfield rotational viscometer, the company significantly improved the accuracy of viscosity testing and successfully passed the unannounced inspection by the regulatory authorities.

Implementation recommendations

To ensure compliance with the requirements of GB1886.256-2024, relevant companies are advised to take action in the following areas:

1. Equipment upgrade:Invest in advanced viscometers and gas chromatographs to ensure that the detection accuracy meets the standard requirements.
2. Staff training:Organize technical personnel to learn the detection methods and reagent preparation specifications in the new standard to improve their operational level.
3. Supply chain management:Establish long-term cooperative relationships with qualified suppliers to ensure the stable quality of raw materials.
