This document, part of EN 13130, specifies an analytical procedure for the determination of vinyl acetate in the four conventional EU food simulants, water, 10 % (v/v) ethanol aqueous solution; 3 % (w/v) acetic acid aqueous solution and olive oil or an approved substitute. The level of vinyl acetate monomer determined is expressed as milligrams of vinyl acetate per kilogram of food simulant. The method is appropriate for the quantitative determination of vinyl acetate in approximate analyte concentration range of 1,2 mg/kg to 24 mg/kg food simulant.
NOTE 1 The method should also be applicable to other aqueous food simulants as well as to other fatty food simulants such as sunflower oil and a mixture of synthetic triglycerides.
NOTE 2 The suitability of the fat simulant should be assessed prior to setting up migration tests - it may be found necessary to use sunflower oil or a mixture of synthetic triglycerides if unacceptable interferences are found with olive oil.
