Abstract
Abstract Sausages, such as frankfurters and bolognas, formed in synthetic casings are more easily peeled when the casings are provided with an internal coating of a food grade mineral oil in admixture with an acetylated fatty monoglyceride and about 5 to 30 percent of an alkoxylated type surfactant which is poorly soluble in mineral oil. The coating composition is preferably applied to the interior of the casing as a lubricant during the shirring of the casing on a conventional shirring machine. Other methods of internal coating which are well known in the art may likewise be used for application of the coating solution.
