Animal and vegetable fats and oils - Determination of melting point in open capillary tubes - Slip point (ISO 6321:2021)

Animal and vegetable fats and oils - Determination of melting point in open capillary tubes - Slip point (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.

Tierische und pflanzliche Fette und Öle - Bestimmung des Schmelzpunktes in offenen Kapillarröhrchen - Steigschmelzpunkt (ISO 6321:2021)

Dieses Dokument legt zwei Verfahren zur Bestimmung des Schmelzpunktes von tierischen und pflanzlichen Fetten und Ölen (im Folgenden als Fette bezeichnet) in offenen Kapillarröhrchen fest, allgemein bekannt als Steigschmelzpunkt.
- Verfahren A ist nur auf tierische und pflanzliche Fette anwendbar, die bei Umgebungstemperatur fest sind und keine ausgeprägte Polymorphie zeigen.
- Verfahren B ist auf alle tierischen und pflanzlichen Fette anwendbar, die bei Umgebungstemperatur fest sind, und ist das Verfahren, das auf Fette mit unbekanntem polymorphem Verhalten anwendbar ist.
Zur Bestimmung des Schmelzpunktes von Palmölproben ist das in Anhang A angegebene Verfahren anzuwenden.
ANMERKUNG 1 Bei Anwendung auf Fette mit ausgeprägter Polymorphie führt Verfahren A zu anderen und weniger zufriedenstellenden Ergebnissen als Verfahren B.
ANMERKUNG 2 Fette mit ausgeprägter Polymorphie sind hauptsächlich Kakaobutter und Fette, die merkliche Mengen an 2-ungesättigten, 1,3-gesättigten Triacylglycerinen enthalten.

Corps gras d’origines animale et végétale - Détermination du point de fusion en tube capillaire ouvert (ISO 6321:2021)

Le présent document spécifie deux méthodes de détermination du point de fusion en tube capillaire ouvert, couramment appelé «point de fusion par glissement», des corps gras d’origines animale et végétale (désignés ci-après par «corps gras »).
—    La méthode A est applicable uniquement aux corps gras d’origines animale et végétale solides à température ambiante et qui ne présentent pas un polymorphisme prononcé.
—    La méthode B est applicable à tous les corps gras d’origines animale et végétale solides à température ambiante, et est à utiliser pour les corps gras dont le comportement polymorphique est inconnu.
Pour la détermination du point de fusion par glissement d’échantillons d’huile de palme, la méthode donnée dans l’Annexe A doit être appliquée.
NOTE 1      La méthode A appliquée aux corps gras à polymorphisme prononcé donne des résultats différents et moins satisfaisants que ceux obtenus avec la méthode B.
NOTE 2      Les corps gras présentant un polymorphisme prononcé sont principalement le beurre de cacao et les corps gras contenant des quantités notables de triacylglycérol insaturé-2, saturé-1,3.

Animal and vegetable fats and oils - Determination of saponification value (ISO 3657:2023)
SIST EN ISO 3657:2023

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.

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.

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.

Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of oxidation stability (accelerated oxidation test)
SIST EN 14112:2021

This document specifies a method for the determination of the oxidation stability of fatty acid methyl esters (FAME) at 110 °C, by means of measuring the induction period up to 48 h.
For induction periods higher than 8,5 h the precision is not covered by the precision statement of this method.
NOTE 1 EN 15751 [1] describes a similar test method for oxidation stability determination of pure fatty acid methyl esters and of blends of FAME with petroleum-based diesel containing 2 % (V/V) of FAME at minimum.
NOTE 2 Limited studies on EN 15751 with EHN (2-ethyl hexyl nitrate) on FAME blends indicated that the stability is reduced to an extent which is within the reproducibility of the test method. It is likely that the oxidation stability of pure FAMEs is also reduced in the presence of EHN when EN 14112 is used for testing.
NOTE 3 For the purposes of this document, the term ''% (V/V)'' is used to represent the volume fraction.
