ABSTRACT:
To prevent localized overheating in food products which are to be heated in a microwave oven, an expandable vessel is operatively connected to a food product. When heated the vessel expands moving the food and thereby distributing non-uniformly distributed microwave energy more evenly throughout the food. In one embodiment, the vessel is a folded or coiled bag which retains steam and vapor evolved during the heating operation. The vapor expands the bag causing it to unfold i.e., straighten out thereby moving the food product from one location in the oven to another as microwave energy is applied.
