scope:

This document, part of EN 13130, specifies an analytical procedure for the determination of caprolactam in the food simulants distilled water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and rectified olive oil. The level of caprolactam monomer determined is expressed as mg caprolactam/kg of food or food simulant. The method is appropriate for the quantitative determination of caprolactam in an approximate analyte concentration range of 1,5mg/kg to 30 mg per kilogram of food simulant. This method is also applicable to the determination of the specific migration of caprolactam sodium salt, PM/Ref No 14230, as caprolactam sodium salt instantaneously hydrolyzes to caprolactam when in contact with aqueous media.
