Abstract
Methods of imparting functionality to a food surface are described. In general, a tubular food casing having a surface coated with a polyvinyl alcohol-polyethylene glycol graft copolymer is contacted with a food surface. The functionality is imparted onto the food surface, and in some instances, the polyvinyl alcohol-polyethylene glycol graft copolymer is subsequently removed.
