Animal and vegetable fats and oils - Determination of saponification value (ISO 3657:2020)

Animal and vegetable fats and oils - Determination of saponification value (ISO 3657:2020)

This document specifies a method for the determination of the saponification value of animal and vegetable fats and oils. The saponification value is a measure of the free and esterified acids present in fats and fatty acids.
The method is applicable to refined and crude vegetable and animal fats.
If mineral acids are present, the results given by this method are not interpretable unless the mineral acids are determined separately.
The saponification value can also be calculated from fatty acid data obtained by gas chromatography analysis as given in Annex B. For this calculation, it is necessary to be sure that the sample does not contain major impurities or is thermally degraded.

Tierische und pflanzliche Fette und Öle - Bestimmung der Verseifungszahl (ISO 3657:2020)

Dieses Dokument legt ein Verfahren zur Bestimmung der Verseifungszahl von tierischen und pflanz¬lichen Fetten und Ölen fest. Die Verseifungszahl ist ein Maß für die Menge an freien und veresterten Säuren, die in Fetten und Fettsäuren vorhanden sind.
Das Verfahren ist für raffinierte und rohe pflanzliche und tierische Fette geeignet.
Bei Vorhandensein von Mineralsäuren sind die nach diesem Verfahren erhaltenen Ergebnisse nicht auswertbar, es sei denn, die Mineralsäuren wurden getrennt bestimmt.
Die Verseifungszahl kann auch aus den Fettsäuredaten berechnet werden, die durch gaschromatographische Untersuchungen, wie in Anhang B angegeben, erhalten wurden. Für diese Berechnung ist es notwendig, sich sicher zu sein, dass die Probe keine größeren Verunreinigungen enthält oder dass sie thermisch abgebaut wird.

Corps gras d'origines animale et végétale - Détermination de l'indice de saponification (ISO 3657:2020)

Le présent document spécifie une méthode de détermination de l'indice de saponification des corps gras d'origines animale et végétale. L'indice de saponification est une caractéristique des acides gras libres et estérifiés présents dans les corps gras et acides gras.
La méthode est applicable aux corps gras d'origines végétale et animale raffinés et bruts.
En présence d'acides minéraux, les résultats donnés par cette méthode ne sont plus interprétables si l'on ne dose pas séparément l'acidité minérale.
L'indice de saponification peut également être calculé à partir des données de composition en acides gras obtenues par chromatographie en phase gazeuse, selon l'Annexe B. Pour effectuer ce calcul, il est nécessaire de s'assurer que l'échantillon ne contient aucune impureté importante et qu'il n'est pas dégradé thermiquement.

SIST EN ISO 18363-3:2022

ISO 18363-3:2017 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.
ISO 18363-3:2017 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.

SIST EN ISO 18363-1:2022

ISO 18363-1:2015 describes a procedure for the indirect determination of 3-MCPD esters (bound 3-MCPD) and possible free 3-MCPD after alkaline catalysed ester cleavage and derivatization with phenylboronic acid (PBA). Furthermore, this part of ISO 18363 enables the indirect determination of glycidyl esters (bound glycidol) under the assumption that no other substances are present that react at room temperature with inorganic chloride to generate 3-MCPD.
ISO 18363-1:2015 is applicable to solid and liquid fats and oils. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this part of ISO 18363.

SIST EN ISO 18363-4:2021

This document specifies a rapid 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 alkaline catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC-MS/MS analysis. Glycidyl ester overestimation is corrected by addition of an isotopic labelled ester bound 3-MCPD which allows the quantification of 3-MCPD induced glycidol during the procedure.
This method is applicable to solid and liquid fats and oils. This document also applies to animal fats and used frying oils and fats, but these matrices were not included in the validation. 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.
Milk and milk products (or fat coming from milk and milk products), infant formulas, emulsifiers, free fatty acids and other fats- and oils-derived matrices are excluded from the scope of this document.

This document specifies a method for the semi-quantitative analysis of oils, fats and oil/fat-related samples (deodistillates).
It is applicable to the screening of oils, fats and oil/fat-related samples to obtain main (e.g. triglycerides) and minor (e.g. sterols, sterol esters, tocopherols, wax esters, fatty alcohols, glycerol) component information in one single analysis. For a truly quantitative analysis of pre-identified compound classes, specific methods are more appropriate.
The method can also be used as a useful qualitative screening tool for the relative comparison of sample compositions.

SIST EN ISO 6321:2021

This document specifies two methods for the determination of the melting point in open capillary tubes, commonly known as the slip melting point, of animal and vegetable fats and oils (referred to as fats hereinafter).
—    Method A is only applicable to animal and vegetable fats which are solid at ambient temperature and which do not exhibit pronounced polymorphism.
—    Method B is applicable to all animal and vegetable fats which are solid at ambient temperature and is the method to be used for fats whose polymorphic behaviour is unknown.
For the determination of the slip melting point of palm oil samples the method given in Annex A shall be used.
NOTE 1   If applied to fats with pronounced polymorphism, method A will give different and less satisfactory results than method B.
NOTE 2   Fats which exhibit pronounced polymorphism are principally cocoa butter and fats containing appreciable quantities of 2-unsaturated, 1,3-saturated triacylglycerols.

Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of free and total glycerol and mono-, di-, triglyceride contents
SIST EN 14105:2021

This document specifies a method to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME). The total glycerol content is then calculated from the obtained results.
Under the conditions described, the quantification limits are 0,001 % (m/m) for free glycerol, 0,10 % (m/m) for all glycerides (mono-, di- and tri-). This method is suitable for FAME prepared from rapeseed, sunflower, soybean, palm, animal oils and fats and mixture of them. It is not suitable for FAME produced from or containing coconut and palm kernel oils derivatives because of overlapping of different glyceride peaks.
NOTE 1 For the purposes of this document, the term "% (m/m)" is used to represent the mass fraction.
NOTE 2 Under the common EN 14105 GC conditions squalene can coelute with alpha glycerol monostearate. If the presence of squalene is suspected, EN 17057 can be used to discriminate between squalene and glycerol monostearate.
WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.
