11 Polymer-based sausage casing US11122140 2005-05-04 US08568638B2 2013-10-29 Ruben Garcia Cruz
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.

16 Packaging envelope US08288574 1994-08-10 US06824846B1 2004-11-30 Hans-Werner Meixner
Packaging envelope or packaging bag consisting of at least two plies, of which the one ply is elastic and the other ply is a gas-barrier layer. The inner ply can consist of a food-compatible material, so that foods, in particular meat, can be placed in the packaging envelope or the packaging bag. For packaging, the envelope is expanded and the object then inserted. After the insertion, the envelope contracts through its flexibility in the direction of the center line of the envelope and automatically presses the air present between object and envelope out of the packaging. In the packaging of shapable objects, in particular meat, the envelope presses these objects, in particular the meat, simultaneously into an at least approximately circular cross-sectional shape through the exerted radial forces. The gas-barrier layer prevents the entry of air through the envelope material even for a lengthy storage period.
