Infant formula and adult nutritionals. Determination of vitamin C by (ultra) high performance liquid chromatography with ultraviolet detection ((U)HPLC-UV) Ingestion-build-63114 basic preparation and presentation1 Scope This document specifies a method for the determination of vitamin C (L ascorbic acid) present in all forms of infant and adult formulas (powders, ready to feed liquids and liquid concentrates), using (ultra) high performance liquid chromatography with ultraviolet detection (U)HPLC UV. The application range runs from 2,5 mg 100 g (limit of quantification) to 50 mg 100 g expressed in the product as consumed. The method is able to distinguish
