EVS-EN ISO 22184:2021

This International Standard describes the quantitative liquid chromatographic determination of specific sugars (galactose, glucose, fructose, sucrose, lactose, and maltose) in various milk and milk products, applying arabinose or fucose as internal standards. The method is applicable for the following different dairy matrices: milk, milk powder, chees, whey powder, infant formula, dessert and yogurt. Soy containing dairy products are excluded. The determination of the lactose content in low lactose milk products is excluded.
A sophisticated high performance anion exchange chromatographic method in combination with
pulsed amperometric detection (HPAEC-AD) is applied. With this method the following 13 different
mono- and disaccharides can be separated: fucose, arabinose, galactose, glucose, fructose, sucrose, lactose, lactulose, maltose, melobiose, trehalose, platinose (maltulose) and maltotriose.
