Contamination from Packaging
Accurate results by choosing the appropriate sample preparation techniques.
Packaging is intended to protect foodstuffs from damage due to mechanical effects and contamination. Finding out as much as possible about the chemical interaction between packaging and product is of great interest for food manufacturers. What happens if the packaging itself emits substances not suitable for consumption? The transfer of such undesired compounds from the packaging to the food product is known as migration.
One possibility for evaluating or determining the migration potential is analyzing the packaging material using direct thermal extraction (DTE). A small quantity of the sample is heated in a GERSTEL thermal desorption system in a flow of inert gas to release volatile and semi-volatile compounds from the sample. The analytes are then evaluated using gas chromatography / mass spectrometry.
Complex contaminants such as MOSH and MOAH can be determined with the special GERSTEL MOSH MOAH prep solution.
