Asnjë informacion i shtuar.

This document, part of EN 13130, specifies an analytical procedure for the chemical conversion of HMTA to formaldehyde and the determination of formaldehyde in food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and rectified olive oil. The method is appropriate for the quantitative determination of formaldehyde in approximate analyte concentration range of 3,0 mg to 30 mg formaldehyde per kilogram of food simulant, which corresponds to 2,3 mg to 23,3 mg hexamethylenetetramine per kilogram of food simulant. NOTE The method should also be applicable to other aqueous food simulants as well as to other fatty food simulants e.g. sunflower oil, corn oil or a mixture of synthetic triglycerides.
