Through special screening determinations, it is possible to detect the presence of constituents from items in contact with food that can be released to the food itself.
In terms of analytical conformity assessment, screening thus allows the assessment of the chemical contamination that can lead to toxicological problems arising from migration.
Mérieux NutriSciences suggests this approach to detect volatile, semi-volatile and non-volatile contaminants in materials intended for contact with food and in non-intentionally added substances (NIAS) through specific preparation techniques (for example, solid phase micro-extraction (SPME) from headspace or solvent extraction) and extremely sophisticated analytical techniques (GC-MS, LC-TOF, LC-MS, ICP-MS), as well as screening tests of elements in XRF and toxicological analysis of specific substances.
Mérieux NutriSciences is also able to provide further screening, according to EU Regulation 10/2011 with
- Content of residues on the polymer with a target study of specific molecules,
- Study of non-volatile substances replacing the specific migration, where possible,
- Evaluation studies of the extraction conditions for a specific polymer and a given molecule with regulated food simulants and substitute solvents.
