Abstract
Abstract Bacon is freeze-dried in the raw state to a moisture content of not more than 5 percent and packaged in gas-tight containers for storage purposes. The freeze-dried raw bacon may be cooked prior to packaging in gas-tight containers. It does not spatter during the cooking thereof and the cooked freeze-dried bacon has good storage stability.
