Milk and milk products — Extraction methods for lipids and liposoluble compounds
ISO 14156|IDF 172:2001 specifies methods for the extraction or separation of a representative part of the fat, containing lipids and liposoluble compounds, from milk and milk products. The method is applicable to pretreatment of samples for the methods described in ISO 15884 and ISO 15885. It should be noted that free fatty acids are not part of extracted fat as described in methods for the fat determination in milk, condensed milk, dried milk products, cream and fermented milk.
Lait et produits laitiers — Méthodes d'extraction des lipides et des composés liposolubles
L'ISO 14156|FIL 172:2001 spécifie des méthodes pour l'extraction ou la séparation d'une partie représentative des matières grasses, contenant des lipides et des composés liposolubles, du lait et des produits laitiers. Elle est applicable au prétraitement des échantillons pour les méthodes décrites dans l'ISO 15884 et l'ISO 15885. Il convient de noter que les acides gras libres ne font pas partie des matières grasses extraites comme décrit dans les méthodes de détermination des matières grasses dans le lait, le lait condensé, les produits laitiers secs, la crème et le lait fermenté.

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.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux
de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général
confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d’approbation requis pour les différents types de documents ISO. Le présent document
a été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2
(voir www.iso.org/directives).
L’ISO attire l’attention sur le fait que la mise en application du présent document peut entraîner l’utilisation
d’un ou de plusieurs brevets. L’ISO ne prend pas position quant à la preuve, à la validité et à l’applicabilité de
tout droit de brevet revendiqué à cet égard. À la date de publication du présent document, l’ISO n’avait pas
reçu notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois,
il y a lieu d’avertir les responsables de la mise en application du présent document que des informations
plus récentes sont susceptibles de figurer dans la base de données de brevets, disponible à l’adresse
www.iso.org/brevets. L’ISO ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de
propriété et averti de leur existence.
Les appellations commerciales éventuellement mentionnées dans le présent document sont données pour
information, par souci de commodité, à l’intention des utilisateurs et ne sauraient constituer un engagement.
Pour une explication de la nature volontaire des normes, la signification des termes et expressions
spécifiques de l’ISO liés à l’évaluation de la conformité, ou pour toute information au sujet de l’adhésion de
l’ISO aux principes de l’Organisation mondiale du commerce (OMC) concernant les obstacles techniques au
commerce (OTC), voir www.iso.org/avant-propos.
Le présent document a été élaboré par le comité technique ISO/TC 34, Produits alimentaires, sous-comité
SC 5, Lait et produits laitiers, et la Fédération Internationale du Lait (FIL). Il est publié conjointement par l’ISO
et la FIL.
Cette deuxième édition annule et remplace la première édition (ISO 14156 | IDF 172:2001), qui a fait l’objet
d’une révision technique. Elle intègre également l’Amendement ISO 14156:2001/Amd 1:2007.
Les principales modifications sont les suivantes:
— inclusion de l’ISO 14156:2001/Amd 1:2007.
Il convient que l’utilisateur adresse tout retour d’information ou toute question concernant le présent
document à l’organisme national de normalisation de son pays. Une liste exhaustive desdits organismes se
trouve à l’adresse www.iso.org/fr/members.html.
La FIL (Fédération internationale du lait) est une organisation privée à but non lucratif qui représente les
intérêts des divers acteurs de la filière laitière au niveau international. Les membres de la FIL sont organisés
en comités nationaux, qui sont des associations nationales composées de représentants de groupes d’intérêt
nationaux dans le secteur des produits laitiers, incluant des producteurs laitiers, des acteurs de l’industrie
de transformation des produits laitiers, des fournisseurs de produits laitiers, des universitaires et des
