Food Contact Materials and Packaging Migration

Identify all suspects in food packaging

A Food Contact Material (FCM) is any material approved for food use that comes in contact with food or drink products during manufacturing, packaging, preparation, and storage. They can be made from a variety of materials including plastics, rubber, paper, and metal. The safety of a FCM must be evaluated, as chemicals can migrate from the materials into the food. Food packaging and drinks packaging must be manufactured in compliance with regulations, including good manufacturing practices, so that any potential transfer to foods does not raise food safety concerns, change the composition of the food or have adverse effects on the taste or odor of the product.

The analysis and identification of packaging impurities involve a diverse range of chemicals; from volatiles to high molecular weight non-volatile molecules and even metals. It is essential that they are monitored as they can be toxic to both humans and animals. Targeted and non-targeted packaging migration and food contact material testing is used to identity such compounds, using a wide range of chromatography-mass spectrometry techniques.

Sample extraction

Traditional Soxhlet or reflux techniques, used routinely for extractables and leachables testing, are labor intensive often accounting for more than twice the time spent on actual chromatography. They typically require over 24 hours for extraction and consume large quantities of solvent (>150 mL/sample).

Thermo Fisher Scientific offer automated sample preparation solutions to simplify the process for such demanding extractions, allowing for a reduction in time and repetitive functions, while still providing highly reproducible results.

Volatile analysis

Improved sample handling includes the use of autosamplers that can reduce turnaround times and significantly reduce the cost per analysis. Using automated systems, particularly headspace autosamplers, when analyzing for organic volatiles in food contact materials can increase sample turnaround time and in turn lower costs for high throughput laboratories.

Semi-volatile analysis

Semi-volatile organic impurities are a complex range of chemicals that often require high selectivity and sensitivity analysis for identification and quantification. High-resolution, accurate-mass (HRAM) mass spectrometry is a perfect solution. Interferences are resolved for the cleanest of spectra and enable confident identification of unknowns while still achieving accurate quantification at the lowest levels.

Non-volatile analysis

Non-volatile food contact material compounds, for example phthalates, are amongst the hardest to identify. Identify and confirm more compounds rapidly and with confidence by using a benchtop LC-MS/MS system. By combining UHPLC with quadruple precursor ion selection and high-resolution, accurate-mass (HRAM) detection it is possible to deliver exceptional results.
