MICROWAVE HEATABLE FILMS FOR FOODSERVICE

摘要

A new polymeric composite for microwave cooking and enhanced reheating has been developed. This polymeric composite functions as a microwave absorber, is high-temperature stable, and enables microwave ovens to cook, bake, and reheat in ways that were previously unattainable. Importantly, this polymeric composite can produced as a molded part or as a flexible film substrate. While there are commercially available ceramic materials that are known absorbers, no one has been able to develop flexible film like substrates until now. This technology uses silicon carbide whiskers to deliver the desired effect. The substrate attenuates and absorbs microwaves, converts the microwave energy into heat, and conducts this heat into the food. It is food-contact safe and non-stick. Finally, it is safe for personal use: due to the exceptionally high emissivity of the substrate, it will cool from cooking temperature to room temperature in seconds. This composite material is destined to change microwave food processing. It makes microwave heating more versatile and food-friendly, will open up a whole new realm of microwave cooking, baking, and reheating.
