Identification of NIAS from biodegradable food packaging

Biodegradable packagings are made by combination of several materials creating a multilayer with the properties needed. Each material, including the adhesive, could contain substances that could migrate to the food. In a study, 5 of the 13 compounds identified were nonintentionally added substances; they were neoformed compounds created by the reaction of added compounds in the adhesive.
Three of the 13 compounds identified in the adhesive migrated from the adhesive to Tenax®, the solid food simulant. One of them was an intentionally added substance, and the other two were nonintentionally added substances (NIAS) identified in this work (Analytical and Bioanalytical Chemistry, September 2015).
