Materials and articles in contact with foodstuffs - Plastics - Part 10: Test methods for overall migration into olive oil (modified method for use in cases where incomplete extraction of olive oil occurs)
This European Standard describes test methods for the determination of the overall migration into fatty food simulants from plastics materials and articles, by total immersion of test specimens in a fatty food simulant at any temperatures above 5 °C up to and including, 175 °C for selected times.
When some plastics are tested by the methods in prEN 1186-2, prEN 1186-4, prEN 1186-6, prEN 1186-8, prEN 1186-12 and prEN 1186-13, the soxhlet extraction process does not achieve complete recovery of the absorbed olive oil from the test specimens. In this method, the olive oil is released from the plastics test specimens by dissolving them in chloroform, toluene, xylene or tetrahydrofuran.
This method is suitable for plastics when exposure to olive oil is by total immersion as described in prEN 1186-2, in a cell, as described in prEN 1186-4, in a pouch, as described in prEN 1186-6, and by filling, as described in prEN 1186-8 and to tests carried out at low and high temperature, as described in prEN 1186-12 and prEN 1186-13.
This is provided the plastics are soluble in chloroform, toluene, xylene or tetrahydrofuran and insoluble in methanol and that whenever prEN 1186-2 is referred to in this method the appropriate clause of the relevant part of prEN 1186 is substituted.
The method may also be suitable for plastics which are only partially soluble in chloroform, toluene, xylene or tetrahydrofuran and insoluble in methanol.
NOTE 1 This test method has been written for use with the fatty food simulant, olive oil. The test method can also be used with appropriate modifications with 'other fatty food simulants ' called simulant D - a synthetic mixture of triglycerides, sunflower oil and corn oil. These other fatty food simulants will produce different chromatograms for the simulant methyl esters to those of the methyl esters of olive oil.
Werkstoffe und Gegenstände in Kontakt mit Lebensmitteln - Kunststoffe - Teil 10: Prüfverfahren für die Gesamtmigration in Olivenöl (Modifiziertes Verfahren für die Andwendung bei unvollständiger Extraktion von Olivenöl)
Diese Europäische Norm beschreibt Prüfverfahren zur Bestimmung der Gesamtmigration in Fett-Prüflebensmittel aus Werkstoffen und Bedarfsgegenständen aus Kunststoff, durch vollständiges Eintauchen der Prüfkörper in Fett-Prüflebensmittel bei Temperaturen zwischen 5 °C bis 175 °C für ausgewählte Zeitspannen.
Prüft man einige Kunststoffe nach den Verfahren in prEN 1186-2, prEN 1186-4, prEN 1186-6, prEN 1186-8, prEN 1186-12 und prEN 1186-13, muss festgehalten werden, dass mit Soxhletextraktion keine vollständige Extraktion von absorbiertem Olivenöl aus dem Prüfkörper stattfindet. Das vorliegende Verfahren beschreibt die Freisetzung des Olivenöls aus dem Kunststoffprüfkörper durch Auflösen in Chloroform, Toluol, Xylol oder Tetrahydrofuran.
Dieses Prüfverfahren ist für Kunststoffe geeignet, die nach prEN 1186-2 durch vollständiges Eintauchen in einer Zelle, wie in prEN 1186-4 beschrieben, in einem Beutel, wie in prEN 1186-6 beschrieben, und durch Befüllen, wie in prEN 1186-8 beschrieben, sowie für Prüfungen, die bei tiefen und hohen Temperaturen, wie in prEN 1186-12 und prEN 1186-13 beschrieben, in Kontakt mit Olivenöl durchgeführt werden.
Dies setzt voraus, dass die Kunststoffe in Chloroform, Toluol, Xylol oder Tetrahydrofuran löslich und in Methanol unlöslich sind, und dass immer der entsprechende Abschnitt des relevanten Teils aus der prEN 1186 ersetzt wird, wenn in diesem Prüfverfahren auf prEN 1186-2 Bezug genommen wird.
Dieses Prüfverfahren kann auch für Kunststoffe angewendet werden, die nur eingeschränkt in Chloroform, Toluol, Xylol oder Tetrahydrofuran löslich und in Methanol unlöslich sind.
Matériaux et objets en contact avec les denrées alimentaires - Matiere plastique - Partie 10: Méthodes d'essai pour la migration globale dans l'huile d'olive (méthode modifiée a utiliser en cas d'extraction incomplete de l'huile d'olive)
La présente Norme européenne décrit des méthodes d'essai de vérification de la migration globale des matériaux et objets en matiere plastique dans des simulants gras par immersion totale d'éprouvettes dans un simulant gras a des températures supérieures a 5 °C mais inférieures ou égales a 175 °C pendant des durées définies.
Alors que la migration de certaines matieres plastiques peut etre vérifiée par les méthodes indiquées dans les normes EN 1186 2, EN 1186-4, EN 1186 6, EN 1186 8, prEN 1186 12 et EN 1186 13, la méthode d'extraction au soxhlet ne permet pas une récupération complete de l'huile d'olive absorbée par les éprouvettes. Dans cette méthode, l'huile d'olive est éliminée des éprouvettes en plastique par mise en solution dans du chloroforme, du toluene, du xylene ou du tétrahydrofuranne.
La méthode est applicable aux matieres plastiques exposées a l'huile d'olive par immersion totale comme dans l'EN 1186-2, dans une cellule comme dans l'EN 1186-4, dans un sachet comme dans l'EN 1186 6 ou par remplissage comme dans l'EN 1186 8 mais également a basse et haute température comme dans le prEN 1186 12 et l'EN 1186 13.
La méthode implique que la matiere plastique soit soluble dans le chloroforme, le toluene, le xylene ou le tétrahydrofuranne et insoluble dans le méthanol mais aussi de choisir le paragraphe approprié de la bonne partie de l'EN 1186 chaque fois que référence est faite au prEN 1186 2 dans le présent document.
Elle peut également etre utilisable pour les matieres plastiques partiellement solubles dans le chloroforme, le toluene, le xylene ou le tétrahydrofuranne et insolubles dans le méthanol.
NOTE 1 La présente méthode d'essai a été écrite pour l'huile d'olive. Elle peut également etre 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 mais. Ces autres simulants gras donneront des chromatogrammes des ester

In this method, the olive oil is released from the plastics test specimens by dissolving them inchloroform, toluene, xylene or tetrahydrofuran.This method is suitable for plastics when exposure to olive oil is by total immersion as described in EN 1186-2, in acell, as described in EN 1186-4, in a pouch, as described in EN 1186-6, and by filling, as described in EN 1186-8and to tests carried out at low and high temperature, as described in prEN 1186-12 and EN 1186-13.This is provided the plastics are soluble in chloroform, toluene, xylene or tetrahydrofuran and insoluble in methanoland that whenever prEN 1186-2 is referred to in this method the appropriate clause of the relevant part of EN 1186is substituted.The method can also be suitable for plastics which are only partially soluble in chloroform, toluene, xylene ortetrahydrofuran and insoluble in methanol.NOTE 1This test method has been written for use with the fatty food simulant, olive oil.
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.NOTE 2If it has been established that the overall migration into olive oil from the plastics cannot be determined by use ofeither this method or the methods described in EN 1186-2, EN 1186-4, EN 1186-6 and EN 1186-8 then the use of substitutetests should be considered, see clause 6 of EN 1186-1:2001.2 Normative referencesThis European Standard incorporates by dated and undated reference, provisions from other publications.

EN 1186-10:2002 (E)53 PrincipleThe overall migration from a sample of the plastic, such as polystyrene, is determined as the loss in mass ofspecimens after immersion in olive oil.The selection of the test conditions will be determined by the conditions of use, see clauses 4, 5 and 6 ofEN 1186-1:2002.Test specimens of known mass are exposed to olive oil for the exposure time, at temperatures varying from 5 °C to175 °C, then taken from the olive oil, blotted to remove oil adhering to the surface, and reweighed.The specimens will usually retain absorbed olive oil which is extracted by a dissolution and precipitation procedureand determined quantitatively by gas chromatography, after conversion to methyl esters.
Methylation is carried outby reacting a boron trifluoride/methanol complex with fatty acids formed by hydrolysing the oil with potassiumhydroxide.In case the plastic does not dissolve completely, swelling of the plastic in the solvent should be such that the oliveoil absorbed can be released from the plastic.Depending on the type of plastic an appropriate organic solvent is selected in order to dissolve or swell the plastic.For chloroform soluble plastics like polystyrene and polycarbonate, chloroform is used to release the olive oilabsorbed.For polyolefins, toluene and xylene are used as low density polyethylene shows good solubility in toluene and highdensity polyethylene and polypropylene dissolve or swell sufficiently in xylene.For polyvinylchloride or polyvinylidene chloride, tetrahydrofuran can be applied.Overall migration into the olive oil is calculated by subtracting the mass of olive oil retained by the test specimenfrom the mass of the test specimen after removal from the olive oil, and then subtracting this mass from the initialmass of the test specimen.The total loss in mass is expressed in milligrams per square decimetre of surface area of the test specimenintended to come into contact with foodstuffs and the overall migration is reported as the mean of a minimum ofthree determinations on separate test specimens.To allow for inaccuracies which may arise during the procedure and which may be difficult to detect, due forexample to contamination or loss of oil during the sampling handling stages, quadruplicate determinations arecarried out on the sample allowing for the result from one specimen to be discarded.NOTEBefore starting a migration exercise, the test sample should be
