The present invention relates to a method for manufacturing sausage products by means of co-extrusion, wherein the method comprises the following steps of: A) providing a food dough; B) providing a viscous paste; C) producing by means of co-extrusion a sausage strand with a core of the food dough enclosed by a casing of the paste; D) subdividing the sausage strand into sausage products; and E) guiding the sausage through a fixing bath, whereby the cohesion of the sausage increases.

The present invention provides edible food casing films, a method for producing said edible food casing films, compositions for forming said edible food casing films and the use of said edible food casing films for example as a sausage casing, which food casings are hot water and sodium salt resistant, stable at high temperatures, can be easily shined and are ready to be stuffed with foodstuff, especially by meat, cheese or fish products, but also with vegetarian or vegan foodstuff.

The present invention relates to a tubular, seamless, biaxially stretched, smoke-permeable and water vapour-permeable, colouristically neutral and transparent, single-layer food casing formed from a mixture including 50 to 95% by weight of aliphatic (co)polyamide, 3 to 40% by weight of at least one vinyl (co)polymer having units of N-vinyl-2-pyrrolidone and 1.5 to 7.0% by weight of at least one aliphatic diol and/or aliphatic polyol, based in each case on the weight of the mixture. The diol and/or polyol is homogeneously distributed in a matrix formed by the aliphatic (co)polyamide. The food casing is produced by an extrusion method with biaxial tube stretching and subsequent heat-setting. It is particularly suitable as synthetic sausage casing, especially for raw sausage, such as salami or mettwurst.

The present invention provides edible tubular food casings, a method for producing said edible tubular food casings, compositions for forming said edible tubular food casings and the use of said edible tubular food casings for example as a sausage casing, which food casings are hot water and sodium salt resistant, stable at high temperatures, can be easily shined and are ready to be stuffed with foodstuff, especially by meat, cheese or fish products, but also with vegetarian or vegan foodstuff.

The present disclosure provides a functional additive transferring (co)extruded thermoplastic food casing having a water vapor barrier and/or oxygen barrier effect wherein an inside surface of the thermoplastic food casing has a textured surface which forms a three-dimensional pattern of higher and lower retaining capacity for a functional additive.

Edible tubular casings for meats, such as sausages are described. The casings are comprised of reconstituted collagen combined with natural casing material comprising bovine, porcine or sheep gut, or combinations thereof. Methods for producing the casings by forming a gel consisting of a combination of the natural material and the reconstituted collagen are also described.

The present invention provides a functional additive transferring (co)extruded thermoplastic food casing having a water vapor barrier and/or oxygen barrier effect wherein an inside surface of the thermoplastic food casing has a textured surface which forms a three-dimensional pattern of higher and lower retaining capacity for a functional additive, wherein the thermoplastic food casing having a textured surface in case of a monolayer casing or an inner layer comprising the inside surface having a textured surface in case of a multilayer casing comprises as a main component at least one thermoplastic polymer material selected from the group consisting of (co)polyamides, (co)polyolefins, (co)polyester and vinylidenchloride (co)polymers, wherein the (co)extruded thermoplastic food casing does not comprise a net and/or a material forming a net or any other three dimensional structure on its outside surface, wherein the average thickness of the thermoplastic food casing in the areas having a higher retaining capacity is in a range of from 1 to 100 m, wherein the average thickness of the thermoplastic food casing in the areas having a lower retaining capacity is in a range of from 191 to 2000 m, provided that the thickness difference between the average thickness in the areas having higher retaining capacity and the average thickness in the areas having a lower retaining capacity is in a range of from 160 to 1950 m and that a ratio of the average thickness of the thermoplastic food casing in the areas having a higher retaining capacity and the average thickness of the thermoplastic food casing in the areas having a lower retaining capacity is in a range of from 0.002 to 0.25.

The present invention relates to a method for manufacturing sausage products by means of co-extrusion, wherein the method comprises the following steps of: A) providing a food dough; B) providing a viscous paste; C) producing by means of co-extrusion a sausage strand with a core of the food dough enclosed by a casing of the paste; D) subdividing the sausage strand into sausage products; and E) guiding the sausage through a fixing bath, whereby the cohesion of the sausage increases.

A novel smokable thermoplastic film, smokable by both liquid smoke and gaseous smoke, that may be produced as a film or a tube, as in a food casing. This newly disclosed film is a blend of a polyamide base, an amorphous polyvinyl alcohol and, optionally, an antiblocking agent.

The present invention relates to a tubular, seamless, biaxially stretched, smoke-permeable and water vapour-permeable, colouristically neutral and transparent, single-layer food casing formed from a mixture including 50 to 95% by weight of aliphatic (co)polyamide, 3 to 40% by weight of at least one vinyl (co)polymer having units of N-vinyl-2-pyrrolidone and 1.5 to 7.0% by weight of at least one aliphatic diol and/or aliphatic polyol, based in each case on the weight of the mixture. The diol and/or polyol is homogeneously distributed in a matrix formed by the aliphatic (co)polyamide. The food casing is produced by an extrusion method with biaxial tube stretching and subsequent heat-setting.
