We encounter food every day: whether on the plate, while shopping or in the restaurant. All these encounters have one thing in common: in order for us to be able to consume food as we are used to, it has to be packaged properly for transport and storage. There are a number of specifications and guidelines that have to be taken into account with regard to handling and packaging. One of these guidelines concerns specific migration, which is determined by means of a migration test. In the following, you will learn more about what exactly is meant by specific migration, how it is to be measured and how we can support you in the analysis of specific migration.
In context, the term migration describes the transfer of certain substances and traces of substances from packaging, which is handled during the preservation or transport of food, to the food itself. In this context, the total concentration determined in the product during a migration test for foodstuffs must not exceed a concentration of 10 milligrams/dm2 , while even stricter guideline values apply to infants and young children with regard to total migration.
Specific migration, which is examined by means of a specific migration test, refers to the migration of almost 1000 specific individual substances - including monomers, plasticisers and photoinitiators - which must not exceed a specific migration limit (SML).
Tests for specific migration (SML)/ NIAS screening/individual substance analyses are carried out by means of investigations to assess specific migration (SML) on the basis of migration tests using food simulants or content determinations in the article of demand. In addition, the proportion of migratable individual substances or degradation products and impurities of recipe components is estimated using non-specific analyses ("non-target analyses"), e.g. 10 ppb screening with gas chromatography-mass spectrometer coupling (GC-FID-MS), for risk assessment.
