The validation of a method for determining the migration of trace elements from food packaging materials into food

Levels of heavy metals in candy packages and candies likely to be consumed by small children

“…There are 4 mechanisms by which substances used in printing inks can migrate from the printed surface to the food contact surface: blocking, rubbing, peeling, and diffusion (Bradley et al, 2005). There are several scientific studies on migration of contaminants from packages into food (Castle, Jickells, Gibert, & Harrison, 1990;Parry & Aston, 2004;Summerfield & Cooper, 2001; Thompson, Parry, & Benzing, 1997). Moreover, there has been considerable scientific progress in understanding and modeling the migration of adventitious substances with hazardous potential from packages into 0963-9969/$ -see front matter Ó 2008 Elsevier Ltd.

Migration of inorganic contaminants into dry food from packaging made from recycled paper and board

“…The methodology was based on the procedure developed for testing migration from plastic packaging materials (Thompson et al 1997). Previously, such tests were carried out using liquid simulants and the main difference in this application was that the contact substance was dry food.…”

“…The outcome of the work was a validated, radiotracer method for measuring the migration of potential contaminants into food (Thompson et al 1996(Thompson et al , 1997. In the original study, the radiotracer method was developed to measure migration from plastic packaging into liquids.…”

Radiation treatment for sterilization of packaging materials

“…Besides product identification, the following are important topics to be addressed: effects of the absorbed dose and the desorption temperature; comparison of several commercial (proprietary) films; high-temperature thermal desorption (TDS); the question whether TDS analyzes radiation-induced artifacts rather than genuine products; the possible existence of cyclic radiolysis products; the possibility of identifying an LDPE as irradiated after a dose of only 1 kGy; and a typical trace fragment of antioxidants (Buchalla et al, 2000). Thompson et al (1997) investigated such migration into four standard product simulates: acetic acid, ethanol, olive oil, and deionized water.…”
