Asnjë informacion i shtuar.

This document, part of EN 13130, specifies an analytical procedure for the determination of 4-methyl-1-pentene in food simulants distilled water, 3 % (w/v) aqueous acetic acid aqueous solution, 15 % (v/v) aqueous ethanol aqueous solution and rectified olive oil. The level of 4-methyl-1-pentene monomer determined is expressed as milligrams per kilogram of food simulant. In principle, the method is appropriate for the quantitative determination of 4-methyl-1-pentene at a minimum level of 0,005 mg/kg in all of the four food simulants. However, in the case of interferences, which have been observed for some olive oil batches, the detection limit can be compromised correspondingly. NOTE The method should also be applicable to other aqueous food simulants as well as to other fatty food simulants such as corn oil, sunflower oil and a mixture of synthetic triglycerides.
