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
20、” 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

DD CEN/TS 13130-14:20055 Introduction 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone, PM/Ref. 13600, C22H19NO3, is a monomer used in the manufacture of certain plastics materials and articles intended to come into contact with foodstuffs. After
36、 manufacture residual 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone can remain in the finished product and may migrate into foodstuffs coming into contact with that product. The method has been pre-validated by collaborative trial with two laboratories. DD CEN/TS 13130-14:20056 1 Scope This documen
37、t, part of EN 13130, specifies an analytical procedure for the determination of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil or approved substitute. The level of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-ind
38、olinone determined, is expressed as milligrams of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone per kilogram of food or food simulant. The method is applicable to the quantitative determination of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone in an approximate analyte concentration range of 0,18 m
39、g/kg to 4/ kg of food simulants. NOTE 1 The method should also be applicable to other aqueous food simulants as well as to the other fatty food simulants e.g. a mixture of synthetic triglycerides or sunflower oil. NOTE 2 The suitability of the fat simulant should be assessed prior to setting up migr
40、ation tests. Olive oil has been found to give unacceptable interference in some cases. 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
41、 the referenced document (including any amendments) applies.

42、tion of substances in plastics and the selection of conditions of exposure to food simulants. 3 Principle The level of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone in aqueous food simulants is determined by reverse phase high performance liquid chromatography (HPLC) with UV detection at 235 nm. Fa
43、t simulants are extracted with 80 % aqueous acetonitrile prior to HPLC analysis. Quantification is achieved by calibration against samples of relevant food simulants, fortified with known amounts of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone. The level of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indo
44、linone determined, is expressed as milligrams per kilogram of food simulant. Confirmation of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone is carried out by reverse phase HPLC using an analytical column of different polarity with UV detection at 280 nm. 4 Reagents NOTE All reagents should be of rec
