Materials and articles in contact with foodstuffs - Plastics - Part 6: Test methods for overall migration into olive oil using a pouch
This part of this European Prestandard describes a method of test for the determination of the overall migration from one surface only of plastics in the form of sheet and film, which are intended to come into contact with foodstuffs, by forming the plastics film or sheet into standard pouches and exposure to olive oil for 10 days, 24 h or 2 h at 40 °C or for 2 h at 70 °C. A standard pouch is a pouch with the dimensions as defined in 6.3. This method is most suitable for plastics in the form of films and sheets which are sealable by heat or pressure,...
Werkstoffe und Gegenstände in Kontakt mit Lebensmitteln - Kunststoffe - Teil 6: Prüfverfahren für die Gesamtmigration in Olivenöl unter Verwendung eines Beutels
1 Anwendungsbereich
Dieser Teil dieser Europäischen Norm beschreibt Prüfverfahren für die Bestimmung der Gesamtmigration in fettige Prüflebensmittel aus nur einer Oberfläche von Kunststoffplatten oder -folien, die für den Kontakt mit Lebensmitteln bestimmt sind, indem aus den Kunststoffplatten oder -folien Standardbeutel hergestellt werden und diese dann durch Befüllen bei Temperaturen von über 20 °C bis zu, aber nicht einschließlich, 100 °C für ausgewählte Zeit-abschnitte beansprucht werden.
Ein Standardbeutel ist ein Beutel mit den in 6.3 definierten Maßen.
Dieses Verfahren eignet sich am besten für Kunststoffe in Form von Platten und Folien, die durch Hitze oder Druck versiegelbar sind, ist jedoch speziell auf solche Materialien anwendbar, die aus mehr als einer Schicht oder Oberfläche bestehen, wobei nur die Oberfläche mit dem Prüflebensmittel zu prüfen ist, die für das In-Kontakt-Kommen mit Lebensmitteln vorgesehen ist.
ANMERKUNG Dieses Verfahren wurde für die Verwendung von Olivenöl als fettiges Prüflebensmittel geschrieben. Das Prüfverfahren kann auch bei geeigneten Modifikationen mit "anderen fettigen Prüflebensmitteln", genannt Prüflebensmittel D, angewandt werden, einer künstlichen Mischung von Triglyceriden, Sonnenblumenöl und Maiskeimöl. Diese anderen fettigen Prüflebensmittel werden Chromatogramme der Methylester von den Prüflebensmitteln ergeben, die sich von denen der Methylester von Olivenöl unterscheiden. Für die quantitative Bestimmung des von den Prüfmustern extrahierten Prüflebens-mittels sind geeignete Chromatogramm-Peaks der Methylester von anderen fettigen Prüflebensmitteln auszuwählen.
Das beschriebene Prüfverfahren ist auf die meisten Kunststoffsorten anwendbar, obgleich es einige Kunststoffe gibt, für die es bekanntermaßen nicht anwendbar ist.
Matériaux et objets en contact avec les denrées alimentaires - Matière plastique - Partie 6: Méthodes d'essai pour la migration globale dans l'huile d'olive à l'aide d'un sachet
La présente partie de la norme européenne spécifie une méthode d'essai permettant de déterminer la migration globale dans des simulants gras de plastiques sous forme de film ou de feuille, dont seule une face est destinée à entrer en contact avec des denrées alimentaires, en transformant le film ou la feuille plastique en sachets de référence et en les maintenant remplis d'huile d'olive pendant la durée spécifiée à une température supérieure à 20 °C mais inférieure à 100 °C.
Un sachet de référence est un sachet dont les dimensions sont celles décrites en 6.3.
Cette méthode est généralement applicable aux plastiques sous forme de films et de feuilles scellables par chauffage ou par pression, mais plus particulièrement aux matériaux composés de plusieurs couches, qui doivent être essayés avec des simulants uniquement sur la surface destinée à entrer en contact avec les denrées alimentaires.
NOTE La présente méthode d'essai a été écrite pour l'huile d'olive. Elle peut également être utilisée, avec les modifications qui s'imposent pour d'autres simulants gras appelés du terme générique « simulant D », mélange synthétique de triglycérides, d'huile de tournesol et d'huile de maïs. Ces autres simulants gras donneront des chromatogrammes des esters méthyliques du simulant utilisé différents de ceux des esters méthyliques de l'huile d'olive. Choisir pour le dosage quantitatif du simulant extrait des éprouvettes les pics de chromatogramme correspondant aux esters méthyliques des autres simulants gras.
La méthode d'essai décrite est applicable à la plupart des types de matières plastiques, bien qu'il soit connu qu'elle ne le soit pas à certains.

Further Directives andamendments to existing Directives are expected which could change the legislative requirements which thisstandard supports.
It is therefore strongly recommended that users of this standard refer to the latest relevantpublished Directive(s) before commencement of any of the test or tests described in this standard.EN 1186-6:2002 should be read in conjunction with EN 1186-1:2002.Further Parts of this standard have been prepared, and others are in preparation, concerned with the determinationof overall migration from plastics materials into food simulants.Their titles are as follows:EN 1186 Materials and articles in contact with foodstuffs- Plastics-Part 1Guide to the selection of conditions and test methods for overall migrationPart 2Test methods for overall migration into olive oil by total immersionPart 3Test methods for overall migration into aqueous food simulants by total immersionPart 4Test methods for overall migration into olive oil by cellPart 5Test methods for overall migration into aqueous food simulants by cellPart 7Test methods for overall migration into aqueous food simulants using a pouchPart 8Test methods for overall migration into olive oil by article fillingPart 9Test methods for overall migration into aqueous food simulants by article fillingPart 10Test methods for overall migration into olive oil (modified method for use in cases whereincomplete extraction of olive oil occurs)Part 11Test methods for overall migration into mixtures of
14C-labelled synthetic triglycerideSIST EN 1186-6:2002
The test method can also be usedwith appropriate modifications with 'other fatty food simulants ' called simulant D - a synthetic mixture of triglycerides, sunfloweroil and corn oil.
These other fatty food simulants will produce different chromatograms for the simulant methyl esters to those ofthe methyl esters of olive oil.
Select suitable chromatogram peaks of the methyl esters of the other fatty food simulants for thequantitative determination of the simulant extracted from the test specimens.The test method described is applicable to most types of plastics, although there are some plastics for which it isknown not to be applicable.2 Normative referencesThis European Standard incorporates by dated and undated reference, provisions from other publications.
Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to and revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.
For undated references the latest edition of thepublication referred to applies (including amendments).EN 1186-1:2002, Materials and articles in contact with food – Plastics – Part 1: Guide to the selection of conditionsand test methods for overall migration.ISO 648, Laboratory glassware - One mark pipettes.ISO 4788, Laboratory glassware - Graduated measuring cylinders.3 PrincipleThe overall migration from a sample of the plastics is determined as the loss in mass per unit of surface areaintended to come into contact with foodstuffs.The selection of the conditions of test will be determined by the conditions of use, see clauses 4, 5 and 6 of EN1186-1:2002.Test specimens of known mass and in the form of pouches are filled with olive oil for the exposure time, attemperatures above 20 °C and below 100 °C, then the olive oil is removed, the pouches cut open and the olive oiladhering to the surface is removed by blotting.
The cut portion of each pouch is then reweighed,The specimens will usually retain absorbed olive oil which is extracted and determined quantitatively by means ofgas chromatography after conversion to methyl esters.
Methylation is carried out by reacting a borontrifluoride/methanol complex with fatty acids formed by hydrolysing the oil with potassium hydroxide.
An internalstandard, triheptadecanoin, is added prior to the extraction of the absorbed olive oil from the test specimens.
Thisensures that any active or extractable components of the plastics react with the internal standard, as well as withSIST EN 1186-6:2002
If an unacceptable amount of interference is present thensuitability of one of the 'other fatty food simulants' should be examined, see annex A and 9.3 and 9.5 of EN 1186-1:2002.
If aninterference is present which would interfere with the triheptadecanoin internal standard an alternative internal standard shouldbe used, see annex A, and 9.3 of EN 1186-1:2002.4 ReagentsNOTEAll reagents should be of recognized analytical quality, unless otherwise specified.4.1Olive oil, simulant D, as specified in 5.2 of EN 1186-1:2002.4.2Extraction solvent (see 10.1 of EN 1186-1:2002).4.2.1For non-polar plastics, such as polyethylene and polypropylene:- Pentane 98 % boiling point 36 °C.For polar plastics, such as polyamide and polyacetal:- 95/5 by volume azeotropic mixture of pentane 98 % and ethanol 99 %.NOTE 1Pentane is a very volatil
