Abstract
A food casing that is a tubular film having an internal cellulose surface containing smoke components integrally blended with the cellulose. The invention further includes the method for making the food casing of the invention by blending smoke, usually in the form of an aqueous solution or dispersion of smoke components (liquid smoke), into viscose prior to formation of the viscose into a film by extrusion and regeneration. The food casing of the invention consistently transfers smoke flavor and color to contained food product, has reduced odor, is not sticky, does not gum up processing machinery, does not have degraded color and flavor as a result of exposure to acid or caustic, is easily shirred, deshirred and unrolled, does not yield odiferous dark sticky liquid in premoisturized casing packages and can be readily peeled from processed food product.
