Foreword
This document (CEN/TS 13130-11:2005) has been prepared by Technical Committee CEN/TC 194 “Utensils
in contact with food”, the secretariat of which is held by BSI.
This part of EN 13130 has been prepared within the Standards, Measurement and Testing project, MAT1-
CT92-0006, “Development of Methods of Analysis for Monomers” and has been prepared by Subcommittee
(SC 1) of TC 194 "Utensils in contact with food" as one of a series of test methods for plastics materials and
articles in contact with foodstuffs.
This standard is intended to support Directives 2002/72/EC [1], 89/109/EEC [2], 82/711/EEC [3] and its
amendments 93/8/EEC [4] and 97/48/EC [5], and 85/572/EEC [6].
At the time of preparation and publication of this part of EN 13130 the European Union legislation relating to
plastics materials and articles intended to come into contact with foodstuffs is incomplete. Further Directives
and amendments to existing Directives are expected which could change the legislative requirements which
this standard supports. It is therefore strongly recommended that users of this standard refer to the latest
relevant published Directive(s) before commencement of a test or tests described in this standard.
This part of EN 13130 should be read in conjunction with EN 13130-1.
Further parts of EN 13130, under the general title Materials and articles in contact with foodstuffs - Plastics
substances subject to limitation, have been prepared, and others are in preparation, concerned with the
determination of specific migration from plastics materials into foodstuffs and food simulants and the
determination of specific monomers and additives in plastics. The parts of EN 13130 are as follows.

simulants and the determination of substances in plastics and the selection of conditions of exposure to food
simulants

Introduction
11-aminoundecanoic acid, C H O N, PM/Ref. No 12788 is a monomer used in the manufacture of certain
11 23 2
plastics materials and articles intended to come into contact with foodstuffs. After manufacture, residual
acrylamide can remain in the polymer and may migrate into foodstuffs coming into contact with that product.
This analytical method should be used in conjunction with EN 13130-1, which describes the procedures to be
applied prior to the determination of 11-aminoundecanoic acid in food simulants.
NOTE Although the method is applicable to olive oil, it should be taken into account that 11-aminoundecanoic acid is
unstable in olive oil during storage. Therefore the method should only be applied in case of short exposure periods with
olive oil. Alternatively iso-octane could be used as a substitute fatty food simulant.
1 Scope
This document, part of EN 13130, specifies a method for the determination of
11-aminoundecanoic acid in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous
ethanol, olive oil and iso-octane. The level of 11-aminoundecanoic acid determined is expressed as milligrams
per kilogram of food simulant.
The method is appropriate for the quantitative determination of 11-amino-undecanoic acid in approximate
analyte concentration range of 0,5 mg/kg to 10 mg/kg of food simulants.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 13130-1:2004, Materials and articles in contact with foodstuffs – Plastics substances subject to limitation –
Part 1: Guide to test methods for the specific migration of substances from plastics to foods and food
simulants and the determination of substances in plastics and the selection of conditions of exposure to food
simulants.
3 Principle
The level of 11-aminoundecanoic acid in food simulants is determined by preparing a derivative of
11-aminoundecanoic acid with a fluorescent component. The derivative is subsequently determined by high
performance liquid chromatography (HPLC) and fluorescence detection. Quantification is achieved using the
calibration curve method.
NOTE A method for confirmation of the presence of 11-aminoundecanoic acid has not yet been established.
