GB 31604.40-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Migration of Maleic Acid and Its Acid Anhydride (English Version)
1 Scope
This standard specifies the determination of migration of maleic acid and its acid anhydride in food contact materials and articles.
This standard is applicable to the determination of total maleic acid in food simulants.
2 Principle
Maleic anhydride is transformed to maleic acid when reacting with water and indirectly obtain the migration of maleic acid and its acid anhydride by determining the content of the maleic acid. After soaking the specimen, directly inject the sample for water-based food simulant, extract with sodium bicarbonate solution and purify with C18 solid-phase extraction column for oil-based food simulant, determine by high performance liquid chromatography. Separate with reversed-phase chromatographic column, detect with ultraviolet detector and carry out the quantitative determination by external standard method.
