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 C. 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 C, the migration appeared higher when compared with the samples treated at 25 C. 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.

Cyclospora cayetanensis is a microscopic, intestinal protozoan parasite first reported in 1979 that has been known as cyanobacterium-like, coccidia-like, and as cyclospora-like bodies (CLB). It wasnt until 1993 that it was officially characterized as Cyclospora cayetanensis. Much is still unknown about C. cayetanensis, but it is a known cause of a gastrointestinal infection (cyclosporiasis), with increasing worldwide incidence including cases in the United States and Canada. This document is FSHN0519, one of a series of the Food Science and Human Nutrition Department, UF/IFAS Extension.
