Annotation of standard text ČSN EN 17550 (467068):

Tento analytický postup specifikuje metodu vysokoúčinné kapalinové chromatografie s reverzní fází a UV detekcí (RP-HPLC-UV) pro simultánní stanovení čtyř povolených karotenoidů v krmných směsích a premi-xech pro ryby, jmenovitě astaxanthinu (AXN), kanthaxanthinu (CXN), adonirubinu (ADR) a astaxanthinu dime-thyldisukcinátu (AXN DMDS), a šesti povolených karotenoidů v krmných směsích a premixech pro drůbež, jmenovitě kanthaxanthinu (CXN); kapsanthinu (CSN), ethylesteru beta-apo-8´-karotenové kyseliny (BACARE), citranaxanthinu (CIXN), luteinu (LUT) a zeaxanthinu (ZEA) v úrovních od přibližně 2 mg/kg do přibližně 4 500 mg/kg (v závislosti na konkrétním karotenoidu). Beta-karoten (BCAR) povolený v krmných směsích a premixech pro všechny druhy zvířat byl do předmětu normy také přidán. Analytický postup je vhodný pro účely kvantifikace deklarovaných karotenoidů a potvrzení označování. Tento dokument je použitelný pro krmiva vyrobená s využitím přírodních i syntetických doplňkových látek. Estery xanthofylu jako lutein, zeaxanthin a kapsanthin, které mohou být v krmivu přítomny, nejsou povolenými doplňkovými látkami a nejsou tak předmětem tohoto dokumentu
