High temperature use of food contact materials. - FS2201

Description
A method to measure both global and specific migration from food contact materials into silicone oil at high temperature (150-230C) will be developed. This basic method will include a number of variants applicable to the specific polymers encountered. The final procedure will avoid the need for laboratory staff to handle hot simulant. The final procedure will avoid the need for laboratory staff to handle hot simulant. Results given by the proposed will be compared to migration actually occurring into foods using appropriate low M.Wt compounds and oligomeric materials as migration indicators.
Objective
1. To develop a new stimulant, or stimulating system, to measure global and specific migration from food contact plastics directly and to compare predicted migration with that occurring into foods. The methods to be developed will avoid many of the problems associated with global migration using fatty simulants. 2. To devise time-temperature gradient profiles ( each equilivalent to a single temperature-time condition) in which plastic and simulant is heated under controlled conditions from near ambient to a selected higher temperature which is then held for a period before cooling in a reproducible manner.
