Suspect Screening of Chemicals in Food Packaging Plastic Film by Comprehensive Two‑Dimensional Gas Chromatography Coupled to Time‑of-Flight Mass Spectrometry

The occurrence of additives, such as plasticizers in plastic food packaging, has been documented, but information on their potential migration into foods is limited. In this pilot study, 2D GC–MS was used to identify chemicals extracted from a common stretch plastic film with a series of organic solvents.

Suspect Screening of Chemicals in Food Packaging Plastic Film by Comprehensive Two‑ Dimensional Gas Chromatography Coupled to Time‑of-Flight Mass Spectrometry

In this study, chemicals extracted from a food packaging plastic film with a series of organic solvents were tentatively identified with comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC–TOF–MS). A total of 91 compounds were tentatively identified in the film extracts, based on high mass spectral matching with the US National Institute of Standards and Technology (NIST) mass spectral (MS) library.

The occurrence of additives like plasticizers in plastic food packaging has been documented, but information on their potential migration into foods is limited. In this pilot study, 2D GC–MS was used to identify chemicals extracted from a common stretch plastic film with a series of organic solvents. In total, 91 compounds were tentatively identified, including five PCBs.
