The Barrier Effect of EVOH versus 1,4,7-Triaxocyclotridecane-8,13-Dione, a Non-intentionally Added Compound from Polyurethane Adhesives in Multilayer Food Packaging

摘要

The presence and migration of non-intentionally added substances in food packaging materials are the big concerns nowadays in terms of food safety, and the identification and quantitation are an important analytical challenge. Among non-intentionally added substances, 1,4,7-trioxacyclotridecane-8,13-dione, a by-product resulting from the interaction between ingredients in many polyurethane adhesives, has been identified and quantified.
