The Influence of High-pressure Processing on the Migration of Irganox 1076 from Polyethylene Films

摘要

This study investigated the influence of high-pressure processing (HPP) on the migration of Irganox 1076 from low-density polyethylene films to 10 and 95% ethanol as food simulants. Pouches made from the low-density polyethylene films were pressured at 600 and 800 MPa for 5 min at 25 and 75℃. Control samples were not high-pressure processed. The mass transfer of Irganox 1076 from the films towards the ethanol was monitored over a 40-day period and quantified using a high-performance liquid chromatography method. The results showed a lower level of Irganox migration from the films to the ethanol at lower when compared with higher pressure treatments. At the processing temperature of 75℃, the migration appeared higher when compared with the samples treated at 25℃. The migration in the HPP samples was higher than that of the controls. The results of this study showed that HPP at higher temperatures caused a higher level of chemical migration from polyethylene when compared with samples not treated by this technique.
