Review of analytical approaches for the identification of non-intentionally added substances in paper and board food contact materials

Abstract

Background Food contact materials (FCM) may contain non-intentionally added substances (NIAS) as a result of reaction by-products, oligomers, degradation processes, chemical reactions between packaging materials and foodstuff, or as impurities from the raw materials used for their production.

Evaluation of the presence of potential hazardous substances from plastic and textile fibre recycling

“…The same holds for textiles. Concerning paper recycling, which has a long history already, many analytical studies on targeted and untargeted methods have been published, as recently reviewed by Peters et al (2019). Whenever we deemed such methods complementary, we have included them in below discussion.…”

“…In all cases circular use could lead to accumulation of hazardous substances and new analyses strategies are needed especially for NIAS. The identification of NIAS has not been reported in recycled plastics, contrary to recycled paper (Peters et al, 2019). In this study an overview of the potential hazardous substances that arise from plastic and textile recycling will be made via literature research.…”

Multilayer packaging: Advances in preparation techniques and emerging food applications

“…The different analytical approaches for detection nonintentionally added materials in paper‐based packaging materials have been summarized by Peters et al. (2019). Although multilayer films are mainly used for their potential functional and barrier properties, the recycling process of these composite structures is quite difficult, requiring a cautious analysis of the sustainability aspect before its usage.…”

Determination of volatile non intentionally added substances coming from a starch-based biopolymer intended for food contact by different gas chromatography-mass spectrometry approaches

“…[5]. Environmental pollution and disposal problems of traditional packaging materials, can be overcome by TPS films, which are made mainly from starch finished with different thermoplastic polyesters [6].…”
