The invention relates to a foodstuff casing having a textile supporting layer. The textile supporting layer has, on the side facing the foodstuff, an edible, however, essentially water-insoluble coating. The coating contains solid and/or liquid aromatic substances, dyestuffs and/or food flavorings and can be transferred onto foodstuff located inside the casing. An additional layer, largely or completely formed from water soluble material may be advantageously located between the transferable layer and the textile supporting material.

Food casing having a transferable, edible inner coating

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.

Food casing from a coated, two-dimensional fiber structure

The invention relates to a wet-fast nonwoven, preferably a fiber paper, which comprises fibers from a cellulose-containing material and fibers from a thermoplastic material welded firmly together at their points of intersection. The fibers from the cellulose-containing material are preferably hemp fibers while the fibers from the thermoplastic material are preferably fibers from polypropylene, polyester or polyamide. The fibers are interlinked under the action of pressure and/or heat, especially using a pair of heated calender rolls. The nonwoven or the fiber paper is especially used to reinforce food casings based on regenerated cellulose, especially in artificial cellulose hydrate-based sausage skins.

Nonwoven having improved wet fastness and alkali resistance and cellulose hydrate-based food casing from said nonwoven

The invention relates to a double-viscosed fibrous cellulose sausage casing having a pigmented outer cellulose hydrate layer and an impregnated internal cellulose hydrate layer. The impregnation of the internal cellulose hydrate layer includes a collagen hydrolysate and the outer cellulose hydrate layer includes at least one white pigment, preferably having titanium dioxide pigments. The invention further relates to a method for producing the fibrous cellulose sausage casing and also to its use as artificial sausage casing.

Pigmented and internally impregnated fibrous cellulose sausage casing

The present invention provides a seamless tubular film on a cellulose base, being produced by extruding an aqueous cellulose N-methyl-morpholine-N-oxide spinning solution. The maximum degree of roughness R is from greater than 0.1 &mgr;m to 0.5 &mgr;m and an average degree of roughness R is from 0.005 to 0.014 &mgr;m. On the surface of the tubular film is formed in contact with an electrolyte an electrokinetic potential, the size of which depends on the pH value of the electrolyte.

Seamless tubular film and methods and devices for producing a seamless tubular film materials

The invention relates to a film tube ( ) based on cellulose which is produced by extruding an aqueous cellulose-N-methyl-morpholine-N-oxide (NMMO) solution through a ring nozzle ( ) onto a lining ( ). The film tube ( ) is manufactured by means of a vertically descending spinning in a spinning vat ( ) in which a spinning bath ( ) is located. The film tube ( ) which is submerged in the spinning bath ( ) passes through an air gap ( ) between the underside of a nozzle block ( ) and the upper surface of the spinning bath ( ) and, internally, is pressurized, supported and slightly stretched in a transversal manner by compressed air. The film tube ( ) is filled with an inner bath solution ( ) via a supply tube ( ). An idle roller ( ) is situated near the bottom of the spinning vat ( ) in order to guide the film tube ( ) around and, afterwards, out of the spinning vat ( ) in an upward sloping manner. The film tube is laid flat along a contact section ( ) of the idle roller ( ).

Method and apparatus for the manufacture of a tube made of film on a cellulose basis which an insert reinforces

The invention concerns flat or tubular cellulose-based foodstuff casings which are prepared by extruding (&ldquo;spinning&rdquo;) cellulose dissolved in N-methyl-morpholine-N-oxide by means of a nozzle with an annular gap. After extrusion, the casings are stretched transversely in ambient air by blow moulding, and are then treated with an NMMO-containing aqueous spinning bath. The tubular casings are particularly suitable as sausage casings. Cut open, they can also be used as flat foils.

Cellulose-based foodstuff casings prepared by the amine oxide process

A fiber-reinforced, tubular food casing based on regenerated cellulose, which is produced using an amount of viscose solution which is decreased by 10 to 30% in comparison with the standard casing at a spinning speed increased by at least 25%.

A seamless cellulose-based tubular film is produced by extrusion of an aqueous cellulose-N-methylmorpholine N-oxide solution.

Process and apparatus for producing a seamless cellulose-based tubular

A curved, tubular packing casing of unreinforced cellulose having non-uniform wall thickness in cross-section is disclosed. The area of minimum wall thickness lies opposite the area of maximum wall thickness and is situated in the area of the greater, outer radius of curvature. The maximum wall thickness lies in the range from about 50 to 160 .mu.m, and the minimum wall thickness lies in the range from about 10 to 50 .mu.m. The maximum wall thickness is 50 to 800% greater than the minimum wall thickness.

Curved tubular packing casing

Disclosed is a process for the continuous manufacture of fiber-reinforced tubing based on cellulose hydrate, comprising the steps of impregnating and coating fibrous tubing with an aqueous akaline viscose solution; moving the viscose-treated tubing at a steady speed vertically in a straight line along its longitudinal axis; applying a viscose-regenerating fluid along at least one circular circumferential line to at least the outside of the viscose-treated fibrous tubing; immediately after the application step, passing the tubing with the film of regenerating fluid on its surface through at least one first air section, whereby there is produced a fiber-reinforced tubing based on cellulose hydrate; treating the cellulose hydrate tubing with an aqueous fluid containing a dissolved chemical plasticizer; and drying the plasticized tubing. Also disclosed is an apparatus for carrying out this process.
