適用范圍：This document, part of EN 13130, specifies two methods as follows.Method A is an analytical procedure for the determination of the monomers 1,2-DHB,1,3-DHB and 1,4-DHB in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanoland olive oil. The levels of monomer determined are expressed in milligrams of monomer per kilogram of foodsimulant. The method is appropriate for the quantitative determination of 1,2-DHB and 1,3-DHB at a minimumlevel of 0,15 mg/kg in food simulants and, of 1,4-DHB at a minimum level of 0,10 mg/kg in food simulants.Method B is an analytical procedure for the determination of DHBphen and DHBiph in the food simulantswater, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil. The method is appropriate for thequantitative determination of DHBphen or DHBiph at minimum levels of 0,2 mg/kg and 0,25 mg/kg,respectively, in food simulants.NOTE The methods should also be applicable to other aqueous food simulants as well as to the other fatty foodsimulants e.g. sunflower oil, corn oil or a mixture of synthetic triglycerides.
