Non-stick coated products <br>
Information on the uses of non-stick coatings was obtained from coating manufacturers and observations in retail outlets. Based on this, 26 non-stick coated samples were purchased giving a variety of products, coating/metal types and food contact applications. The coating type was identified and the solvent extractables determined. Coating materials were analysed by a range of techniques. Worst case migration was determined and exposure calculated and compared with the Acceptable Daily Intake (ADI)/Tolerable Daily Intake (TDI) for these substances. Overall migration into food simulants was also measured. Migration of bisphenol A and several phthalates was tested using food simulants.

Metallic kitchenware products <br>
Work in this project was carried out to confirm the applicability of previous recommendations, for testing metal release from kitchenware products, proposed in the recently published project report 'Migration test protocols for the electroplated and dipped metalware intended for food contact'.
A range of kitchenware products is commercially available and is used in contact with foods under a variety of exposure conditions. For the purposes of this study kitchenware products were defined as cookware articles intended for oven and/or stove top use, i.e. pans, cake tins, etc.
<p>
The aim of this project was to determine the migration of potential contaminants from non-stick coated and metal-coated kitchenware products.
<p>
The diversity of kitchenware products commercially available continues to increase, yet little is known of the processes and materials involved in their manufacture and the safety of these items. Much is known about the leaching of lead and aluminium, but other metals may migrate. In addition a variety of kitchenware products exist with non-stick coatings. The migration of any substances present in these coatings also needed to be investigated to ensure the safety of such products.
