  • Publication number: 20140050823
    Abstract: 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.

  • Patent number: 8440277
    Abstract: Disclosed is an intrinsically stable shirred, tubular, single-layer or multilayer food casing that preferably has a sigma-5 value (longitudinal/transversal, measured in a moist state) of less than 20/20 N/mm2. Said casing is preferably shirred at a ratio of 100:1 or more, preferably 120:1 to 500:1, and is essentially made of synthetic polymers. The shirred casing can be stored and transported without using a net-type envelope and is particularly suitable for processing on fully automatic sausage stuffing, portioning, clipping, and twisting devices.

  • Publication number: 20120308750
    Abstract: A tubular elasticated net used for cooking layered or rolled meat products such as cooked ham has independent elastic (12) and inextensible (13) weft threads. The inextensible threads (13) limit the diametral expansion of the tube to the desired shape of the finished product, while the elastic thread (12) squeezes the meat during cooking.

  • Patent number: 8323712
    Abstract: A process accelerating the ripening of raw sausages by incorporating a casing having a water vapor permeability of less than 600 g/m2 d at a relative humidity of less than 60%. Preferably, the process employs casings having a water vapor permeability of 50 to 400 g/m2 d, more preferably 70 to 300 g/m2 d, particularly preferably 80 to 200 g/m2 d. The process concerns, in particular, single-layered or multilayered casings made of thermoplastics, optionally also coated textile fiber skins or cellulose fiber skins.

  • Patent number: 8318274
    Abstract: The invention relates to a food casing from a two-dimensional fiber structure, which is coated on one or both sides with acrylic resin. The acrylic resin is combined with at least one other natural and/or synthetic polymer. The acrylic resin in the coating may be admixed with the other polymer. The latter can also form a layer of it's own. On the inside of the casing (i.e. on the side facing the food), this coating prevents gelling out, while at the outside it has a mainly permeability-increasing effect. The casing is particularly used as artificial sausage casing, especially for cooked-smoked sausages.
