Asnjë informacion i shtuar.

This document, part of EN 13130, specifies analytical procedures for the determination of 1-octene and THF in food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil. The level of 1-octene and THF monomer determined is expressed as milligrams of monomer per kilogram of food simulant. The methods are appropriate for the quantitative determination of 1-octene in the range of 2 mg/kg to 30 mg/kg in food simulants and of THF in the range of 0,06 mg/kg to 1,5 mg/kg in food simulants. NOTE The method should also be applicable to other aqueous food simulants as well as to the other fatty food simulants e.g. sunflower oil, corn oil or a mixture of synthetic triglycerides.
