Asnjë informacion i shtuar.

This document, part of EN 13130, specifies a procedure for the determination of 1,3-benzenedimethanamine (also known as 3-(aminomethyl)-benzylamine or m-xylylene diamine (m-XDA)) monomer, hereinafter referred to as m-XDA, in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil. The level of m-XDA monomer determined is expressed as milligrams of m-XDA per kilogram of food simulant in the above mentioned food simulants. NOTE In addition to the instability of m-XDA observed in olive oil, the test laboratory could not detect any m-XDA peak from the olive oil work-up procedure. Based on some control checks, the assumption of the test laboratory was that the extraction from the olive oil does not work. Therefore, it is recommended that the food simulant 95 % ethanol or iso-octane be applied as substitute fatty simulants instead of olive oil. It is believed that 95 % ethanol and iso-octane can be treated in the same way as 15 % v/v aqueous ethanol and olive oil simulant, respectively. Corresponding investigations were not possible within the project.
