Animal and vegetable fats and oils - Determination of saponification value (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.
Tierische und pflanzliche Fette und Öle - Bestimmung der Verseifungszahl (ISO 3657:2023)
Dieses Dokument legt ein Verfahren zur Bestimmung der Verseifungszahl von tierischen und pflanzlichen 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 auf raffinierte und rohe pflanzliche und tierische Fette anwendbar.
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 erhalten wurden, wie in Anhang B angegeben. 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 3657:2023)
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.
Živalske in rastlinske maščobe ter olja - Določevanje števila umiljenja (ISO 3657:2023)
Ta dokument določa metodo za določevanje števila umiljenja živalskih in rastlinskih maščob ter olj. Umiljenje je meritev prostih in esterificiranih kislin, prisotnih v maščobah in maščobnih kislinah.
Metoda se uporablja za rafinirane in surove rastlinske in živalske maščobe.
Če so prisotne mineralne kisline, rezultatov, pridobljenih s to metodo, ni mogoče interpretirati, razen če se mineralne kisline določijo ločeno.
Umiljenje je mogoče izračunati tudi na podlagi podatkov o maščobnih kislinah, pridobljenih z analizo plinske kromatografije, kot je podana v Dodatku B. Za ta izračun je treba preveriti, da vzorec ne vsebuje večjih nečistoč in da ni termično razkrojen.
