(Main)Animal and vegetable fats and oils - Determination of fatty-acid-bound chloropropanediols (MCPDs) and glycidol by GC/MS - Part 3: Method using acid transesterification and measurement for 2-MCPD, 3-MCPD and glycidol (ISO 18363-3:2024)
Animal and vegetable fats and oils - Determination of fatty-acid-bound chloropropanediols (MCPDs) and glycidol by GC/MS - Part 3: Method using acid transesterification and measurement for 2-MCPD, 3-MCPD and glycidol (ISO 18363-3:2024)
This document specifies a procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3‐MCPD esters (bound 3‐MCPD) and glycidyl esters (bound glycidol) in a single assay, based on acid catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC/MS analysis.
This document is applicable to solid and liquid fats and oils. For all three analytes the limit of quantification (LOQ) is 0,1 mg/kg and the limit of detection (LOD) is 0,03 mg/kg.

Dieses Dokument legt ein Verfahren für die gleichzeitige Bestimmung von 2 MCPD-Estern (gebundenem 2 MCPD), 3 MCPD-Estern (gebundenem 3 MCPD) und Glycidylestern (gebundenem Glycidol) in einer einzigen Prüfung fest, basierend auf einer vor der GC/MS-Analyse erfolgenden säurekatalysierten Esterspaltung und Derivatisierung der abgespaltenen (freien) Analyten mit Phenylboronsäure (en: phenylboronic acid, PBA).
Dieses Dokument ist auf feste und flüssige Fette und Öle anwendbar. Für alle drei Analyten liegt die Bestimmungsgrenze (LOQ, en: limit of quantification) bei 0,1 mg/kg und die Nachweisgrenze (LOD, en: limit of detection) bei 0,03 mg/kg.
Corps gras d'origines animale et végétale - Détermination des esters de chloropropanediols (MCPD) et d'acides gras et des esters de glycidol et d'acides gras par CPG/SM - Partie 3: Méthode par transestérification acide et mesure du 2-MCPD, du 3-MCPD et du glycidol (ISO 18363-3:2024)
Le présent document spécifie un mode opératoire permettant la détermination simultanée des esters de 2-MCPD (2-MCPD lié), des esters de 3-MCPD (3-MCPD lié) et des esters de glycidol (glycidol lié) en un seul essai, basé sur le clivage des esters par catalyse acide et la dérivatisation des analytes clivés (libres) à l’acide phénylboronique (PBA) avant analyse par CPG/SM.
Le présent document est applicable aux corps gras solides et liquides. Pour l’ensemble des trois analytes, la limite de quantification (LOQ) est de 0,1 mg/kg et la limite de détection (LOD) est de 0,03 mg/kg.
Živalske in rastlinske maščobe ter olja - Določevanje maščobno-kislinsko vezanih kloropropandiolov (MCPD) in glicidola z GC/MS - 3. del: Metoda z uporabo kislinske transesterifikacije in meritev 2-MCPD, 3-MCPD in glicidola (ISO 18363-3:2024)
Standard ISO 18363 določa postopek za hkratno določevanje estrov 2-MCPD (vezan 2-MCPD), estrov 3-MCPD (vezan 3-MCPD) in glicidil estrov (vezan glicidol) v enem samem testu, ki temelji na cepljenju estrov, kataliziranih s kislino, in derivatizaciji razcepljenih (prostih) analitov s fenilboronsko kislino (PBA) pred analizo GC/MS.
Standard ISO 18363-3 se uporablja za trdne in tekoče maščobe ter olja. Za vse tri analite je meja kvantifikacije (LOQ) 0,1 mg/kg, meja zaznavanja (LOD) pa 0,03 mg/kg.
