Description of BS ISO 23443:2020 2020This document specifies a method for the quantitative determination of ?-carotene and lycopene in infant formula and adult nutritionals in solid (i.e. powders) or liquid (i.e. ready-to-feed liquids and liquid concentrates) forms using reversed-phase ultra-high performance liquid chromatography (RP-UHPLC) and UV-visible detection. The application range runs from 1 ?g/100 g to 1 500 ?g/100 g for lycopene and from 1 ?g/100 g to 2 250 ?g/100 g for ?-carotene. Based on the single-laboratory validation, the limit of detection (LOD) was 0,1 ?g/100 g and the limit of quantification (LOQ) was 0,3 ?g/100 g for each carotenoid. The method does not apply to materials that contain measurable levels of ?-apo-8?-carotenal. The reproducibility data meets the requirements given in References [8] and [10]. Annex C specifies the determination of lutein. The reproducibility data does not meet the requirements given in Reference [9].
