Determination of migrants in and migration from nylon food packaging

Abstract

A method was developed to determine the amount of residual oligomers in nylon food packaging. In addition, a method was developed to measure oligomers that migrate to a food‐simulating liquid (oil) during oven cooking conditions. It was found that the total amount of nylon 6/66 oligomers that migrated from an oven baking bag to oil after heating for 30 min at 176°C was 15.5 μg/g (ppm) or 11.9 μg/cm², which represented 43% of the total amount of oligomers present in the packaging material.
