This document, part of EN 13130, specifies an analytical procedure for the determination of 1,1,1-trimethylolpropane in food simulants distilled water, 3 % (w/v) acetic acid aqueous solution, 15 % (v/v) ethanol aqueous solution and rectified olive oil. The method is appropriate for the quantitative determination of 1,1,1-trimethylolpropane in approximate analyte concentration range of 0,6 mg/kg to 12 mg/kg food simulant.
NOTE The method should also be applicable to other aqueous food simulants as well as to the other fatty food simulants e.g. sunflower oil, corn oil or a mixture of synthetic triglycerides.
