Safety assessment of microwave susceptors and other high temperature packaging materials.
A number of packaging materials are being used not only to contain food during distribution but also to serve as the cooking container. The higher temperatures that these materials reach led the US Food and Drug Administration (FDA) to issue an intent to publish new regulations in 1989. The food and packaging industries responded by conducting extensive research and submitting the results to FDA. The methods used and results obtained are discussed. Most of the data were focused on microwave susceptors and the volatile compounds generated. One project showed that for a specific product, popcorn, there was no transfer into the food. Work is continuing to validate methods to test for non-volatile compounds. In addition to susceptors, various paper and plastic materials are used in dual ovenable (microwave and conventional ovens) applications. Most of the research on these materials has investigated the food contact temperatures on testing for migrants. An update on the current regulatory status of packaging materials intended for high temperature use in the US is discussed.
