Food processors and food safety experts prefer that food be irradiated after packaging to prevent post-irradiation contamination. Food irradiation has been studied for the last century. However, the implementation of irradiation on prepackaged food still faces challenges on how to assess the suitability and safety of these packaging materials used during irradiation. Irradiation is known to induce chemical changes to the food packaging materials resulting in the formation of breakdown products, so called radiolysis products (RP), which may migrate into foods and affect the safety of the irradiated foods. Therefore, the safety of the food packaging material (both polymers and adjuvants) must be determined to ensure safety of irradiated packaged food. Evaluating the safety of food packaging materials presents technical challenges because of the range of possible chemicals generated by ionizing radiation. These challenges and the U.S. regulations on food irradiation are discussed in this article.

The RPs formed upon irradiation of a polymer or adjuvant could migrate into food and affect odor, taste, and safety of the irradiated food (Deschênes et al. 1995; Welle, Mauer, and Franz 2002; Franz and Welle 2004; Stoffers et al. 2004). ...

A careful mixture of screw configurations, mass flow rates and RPM enabled average residence times of approximately 10 min to be achieved in the extruder. While the conversions obtained in this study were low in comparison to batch processes, the procedure provides opportunities for enhancing specific product characteristics. Future studies should be designed to provide a fundamental understanding of the reactions and mechanisms associated with reactive extrusion

The dissolved PETE was diluted with an additional 60 mL of MC to freely disperse the butyric acid in the solution. MC was used to facilitate dissolution of PETE through swelling, as observed by Haga (1981). The PETE ...

The U. S. Food and Drug Administration is considering development of a guidance document for testing levels of contaminants that might be retained through paper recycling processes. An analytical procedure was developed using paper spiked with suspected contaminants at concentrations of 1-50 ppm in the paper. Benzophenone, dimethyl phthalate, anthracene, methyl stearate, and pentachlorophenol were introduced by soaking the paper in a solution in acetone at 25 degrees C for 24 h; the paper was removed and dried by evaporating the solvent with nitrogen. The model contaminant residues were extracted from the paper using ultrasonication and quantified by GC with flame ionization and electron capture detectors. Recoveries from the spiked paper were 80-109% with a repeatability of +/-4%. The method was also used to analyze commercial recycled paperboard to validate its applicability.
