GB 31604.29-2023 National Food Safety Standard for Food Contact Materials and Products - Determination of Migration of Acrylic Acid, Methacrylic Acid and Their Esters
GB 31604.29-2023
Basic Information
Scope
This standard specifies the determination methods for the migration of acrylic acid, methacrylic acid, and their esters in food contact materials and products.
Part I: Gas chromatography-mass spectrometry is suitable for the determination of the migration of 18 types of acrylic esters and methacrylic esters in food contact materials and products, including 2-acrylic acid-2-methylpropionyl ester, ethyl acrylate, n-butyl acrylate, isopropyl acrylate, propyl acrylate, 2-acrylic acid-1,1-dimethylethyl ester, benzyl acrylate, 2-octyl acrylate, sec-butyl acrylate, ethyl methacrylate, isobutyl methacrylate, butyl methacrylate, 2-methyl-2-acrylic acid-1,1-dimethylethyl ester, phenyl methacrylate, 2-methyl-2-acrylic acid propyl ester, and sec-butyl methacrylate.
Part II: Liquid chromatography is suitable for the determination of the migration of 6 types of acrylic acid and methacrylic acid and their esters in food contact materials and products, including acrylic acid, methacrylic acid, ethyl acrylate, 2-hydroxyethyl-2-methyl-2-acrylic acid ester, methyl acrylate, and methyl methacrylate.
