Tierische und pflanzliche Fette und Öle - Bestimmung der Anisidinzahl (ISO 6885:2016)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Anisidinzahl in tierischen und pflanzlichen Fetten und Ölen fest. Diese ist ein Maß für die Menge an vorhandenen Aldehyden (vorwiegend α, β-unge¬sättigte Aldehyde).
Milch und Milcherzeugnisse (oder Fett aus Milch und Milcherzeugnissen) sind vom Anwendungsbereich dieser Internationalen Norm ausgenommen.

Corps gras d'origines animale et végétale - Détermination de l'indice d'anisidine (ISO 6885:2016)

ISO 6885:2016 spécifie une méthode de détermination de l'indice d'anisidine qui correspond à un mesurage de la quantité d'aldéhydes (principalement des aldéhydes α, β insaturés) présents dans les corps gras d'origines animale et végétale.
Le lait et les produits laitiers (ou les corps gras issus du lait et des produits laitiers) sont exclus du domaine d'application de la présente Norme internationale.

Rastlinske in živalske maščobe in olja - Določevanje anisidinskega števila (ISO 6885:2016)

Ta mednarodni standard določa metodo za določevanje anisidinske vrednosti rastlinskih in živalskih maščob ter olj. To je meritev količine prisotnih aldehidov (v glavnem α, β-nenasičenih aldehidov). Mleko in mlečni izdelki (ali maščoba iz mleka in mlečnih izdelkov) niso zajeti v tem mednarodnem standardu.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

3.1
anisidine value
one hundred times the increase in absorbance, measured at a wavelength of 350 nm in a 10 mm
cell, of a test solution when reacted with p-anisidine under the test conditions specified in this
International Standard
Note 1 to entry: The anisidine value has no dimensions, and is calculated and quoted on the basis of 1 g of the test
sample in 100 ml of a mixture of solvent and reagent.
