Direct Thermal Extraction Analysis of Food Packaging Material
Knowledge about packaging/product interaction is of great interest to food manufacturers in order to control product quality over the course of its shelf-life. Scalping is the loss of components from a product to its packaging. Migration is the transfer of unwanted compounds from the packaging to the food product. Both processes are undesirable and can cause off odors or off flavors in a product.
An application note describes the use of the GERSTEL MultiPurpose Sampler (MPS) fitted with a Thermal Desorption Unit (TDU) and a Cooled Injection System (CIS 4) PTV-type Inlet for the automated direct thermal extraction analysis of packaging for three different brands of sandwich cookies, sandwich crackers and soft and chewy candy.
The results show that direct thermal extraction is a very good method for quantification as well as assessment of quality defects that may arise due to compounds introduced from food packaging. The method requires very little sample preparation.
