(Main)Animal and vegetable fats and oils - Determination of iodine value (ISO 3961:2013)
Animal and vegetable fats and oils - Determination of iodine value (ISO 3961:2013)
ISO 3961:2013 specifies a reference method for the determination of the iodine value (commonly known in the industry as IV) of animal and vegetable fats and oils, hereinafter referred to as fats.
An annex describes a method for the calculation of the IV from fatty acid compositional data. This method is not applicable to fish oils. Furthermore cold-pressed, crude and unrefined vegetable oils as well as (partially) hydrogenated oils can give different results by the two methods. The calculated IV is affected by impurities and thermal degradation products.
Tierische und pflanzliche Fette und Öle - Bestimmung der Iodzahl (ISO 3961:2013)
Diese Internationale Norm legt ein Bezugsverfahren zur Bestimmung der Iodzahl (im industriellen Bereich gemeinhin bekannt als IZ) in tierischen und pflanzlichen Fetten und Ölen fest, die nachfolgend als Fette bezeichnet werden.
Anhang B beschreibt ein Verfahren zur Berechnung der IZ aus Daten zur Fettsäurezusammensetzung. Dieses Verfahren ist nicht auf Fischöl anwendbar. Außerdem können kaltgepresste, unverarbeitete und nicht raffinierte pflanzliche Öle sowie (teilweise) hydrierte Öle unterschiedliche Ergebnisse bei den zwei Verfahren haben. Die berechnete Iodzahl wird durch Verunreinigungen und durch thermische Degradationsprodukte beeinträchtigt.
ANMERKUNG Das Verfahren in Anhang B beruht auf dem offiziellen AOCS-Verfahren Cd 1c 85 [9] [Leitfaden zur empfohlenen Praxis der American Oil Chemists' Society (Amerikanische Öl-Chemiker-Gesellschaft)].
Corps gras d'origines animale et végétale - Détermination de l'indice d'iode (ISO 3961:2013)
L'ISO 3961:2013 spécifie une méthode de référence pour la détermination de l'indice d'iode (communément appelé II dans le secteur industriel) des huiles et graisses d'origines animale et végétale, désignées par le terme corps gras.
Une annexe décrit une méthode de calcul de l'II à partir de données relatives à la composition en acides gras. Cette méthode ne s'applique pas aux huiles de poisson. Par ailleurs, les huiles végétales issues de pression à froid, brutes et non raffinées ainsi que les huiles (partiellement) hydrogénées peuvent donner des résultats différents selon les deux méthodes. L'II calculé est affecté par les impuretés et les produits de dégradation thermique.
Rastlinske in živalske maščobe in olja - Ugotavljanje jodnega števila (ISO 3961:2013)
Ta mednarodni standard določa referenčno metodo za ugotavljanje jodnega števila (v industriji splošno znan kot IV) v živalskih in rastlinskih maščobah in oljih (v nadaljevanju: „maščobe“). V Dodatku B je opisana metoda za izračun IV iz podatkov o sestavi maščobne kisline. Ta metoda se ne uporablja za ribja olja. Rezultati za nerefinirana rastlinska olja in (delno) hidrogenirana olja, pridobljeni s tema dvema metodama, se lahko razlikujejo. Na izračunani IV vplivajo nečistoče in termično razkrajanje.
