A polymer-based sausage casing suitable for use with uncooked meats such as chorizo is disclosed. A polymer resin is blended with a silicon-based barrier control agent, preferably a polyhedral oligomeric silsesquioxane, to increase the permeability of the sausage casing. The resultant blend can be biaxially stretch-oriented to produce a single-layered polymer-based sausage casing suitable for use with uncooked sausage meats such as chorizo, and specifically suitable for the gas and moisture permeability needed during the curing process for uncooked sausage meats. Such polymer-based casings can also be employed for cooked sausages by choosing a silicon-based barrier control agent that increases gas and moisture barrier, thereby increasing shelf-life for unpeeled sausages. A method for improving the peelability of cooked sausage casings by injecting a thin coating of a releasing agent, without the addition of a surfactant, into the sausage casing during the shirring process is also disclosed. The releasing agent is a hydroxypropyl methylcellulose solution that creates a low viscosity releasing agent that effectively improves peelability from any type of sausage casing, but preferably for use with the polymer-based sausage casing of the present invention.

The invention relates to a polymer-based casing for sausages which is designed to be used with uncooked meats such as chorizo. According to the invention, a polymer resin is mixed with a silicon-based barrier control agent, preferably a polyhedral oligomeric silsesquioxane, in order to increase the permeability of the sausage casing. The resulting mixture can be stretched and oriented biaxially in order to produce a polymer-based sausage casing comprising a single layer, which can be used with uncooked meat in the form of sausages, such as chorizo, and which is specifically designed to enable the gas and moisture permeability which is necessary during the curing of uncooked meats in the form of sausages. The inventive polymer-based casing can also be used for cooked sausages by selecting a silicon-based barrier control agent which increases the gas and moisture barrier, thereby increasing the shelf life of cased sausages. The invention also relates to a method of improving the casing detachment capacity for cooked sausages involving the injection of a thin coating of a release agent into the sausage casing during the gathering process, without the addition of a surface active agent. The aforementioned release agent is a hydroxypropyl methylcellulose solution which creates a low-viscosity release agent which effectively improves the detachment capacity of any type of casing for sausages, but which is preferably used with the inventive polymer-based sausage casing.
