Determination of migrants in and migration from nylon food packaging

摘要

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℃ was 15.5 μg/g (ppm) or 11.9 μg/cm~2, which represented 43% of the total amount of oligomers present in the packaging material.
