Abstract
Abstract A dehydrated citrus peel is produced by a method wherein raw fresh citrus peel is immersed in hot vegetable oil and under atmospheric pressure to partially dehydrate the peel. Vacuum is then applied to further dehydrate the peel to a moisture content of 15 percent or less, and the peel is then separated from the oil and drained. In some instances the dehydrated peel is finally impregnated with a hardenable polyol-sugar composition.
