适用范围：This document, part of EN 13130, specifies an analytical procedure for the determination of maleicacid in the four conventional food simulants, water, 3 % w/v aqueous acetic acid, 15 % v/v aqueousethanol and olive oil or approved substitute. The level of maleic acid determined is expressed asmilligrams of maleic acid per kilogram of food or food simulant. The method is appropriate for thequantitative determination of maleic acid in approximate analyte concentration range of 5 mg/kg to 60mg/kg in the above mentioned food simulants.This method is also suitable for the determination of maleic anhydride in the four food simulants asthe anhydride is hydrolyzed rapidly and completely to maleic acid during sample preparation. Thelevel of maleic anhydride is then expressed as milligrams of maleic acid per kilogram of food simulant.NOTE The method should also be applicable to other aqueous food simulants as well as to the other fattyfood simulants, e.g. sunflower oil, corn oil or a mixture of synthetic triglycerides. The suitability of the fat simulantshould be assessed prior to setting up migration tests - it may be found necessary to use sunflower oil or HB 307if unacceptable interferences are found with olive oil.
