Abstract
Abstract Polydextrose compound containing anti-pleat lock coatings, food casings containing said coatings, and a method for their production which comprises applying to the surface thereof an aqueous coating composition containing a polydextrose compound are disclosed. The coated food casings exhibit improved food release characteristics, improved resistance to strand breakage, and improved anti-pleat lock characteristics.
