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%.

Fiber-reinforced cellulose-hydrate-based food casing produced with a

A modified liquid smoke solution containing unmodified aqueous liquid smoke solution, an alkaline neutralizing agent, a synthetic and/or natural oil, a viscosity-increasing component, and one or more emulsifier(s) can be applied to the inner and/or outer surface of a cellulose food casing resulting in uniform smoke transfer to encased food.

Tubular food casing having a modified liquid smoke solution applied

A fiber-reinforced cellulose-based food casing which comprises alginic acid and/or alginate, and fats, fat-like compounds, and/or oils and a non-reinforced cellulose-based food casing which comprises a copolymer containing 80 to 20 mol % of units of the formula I and 20 to 80 mol % of units of the formula II or III ##STR1## in which R.sup.1 to R.sup.4 are identical or different and are hydrogen or (C.sub.1 -C.sub.6)alkyl,

Cellulose-based food casing having improved ripening properties

The invention relates to an optionally fiber-reinforced foodstuff casing based on cellulose hydrate, which is impregnated on the inside with a mixture containing 40 to 200 mg/m.sup.2 of an adhesive component and 20 to 2000 mg/m.sup.2 of a non-stick component. The ratio by weight of adhesive to non-stick component is between 4:1 and 1:4. The foodstuff casing is used as sausage casing, in particular for keeping sausage, which has a second packaging in the form of a film or is provided with a dip coating. The casing shows improved peelability.

Foodstuff casing based on cellulose hydrate with improved peelability

A cellulose hydrate-based flat or tubular film which is useful as a food casing, particularly preferably as a sausage casing. In addition to cellulose hydrate, it contains a homopolymer having units of N-vinylpyrrolidone, N-vinylpyridone or N-vinylcaprolactam and/or a copolymer containing these units and additionally units of the formulae II and/or III: ##STR1##

Cellulose hydrate-based flat or tubular film

The invention relates to a tubular food casing, in particular a sausage casing, based on cellulose, which has a coated inner side for improved peelability which is achieved by the presence of polytetrafluoroethylene in the coating solution.

Tubular food casing having improved peelability

A tubular food casing, particularly sausage casing, wherein the inner surface of a sausage casing based on cellulose, is provided with a coating comprising alginates, alginic acid, chitosans, or a combination of these active substances, is distinguished by improved peelability.

Tubular food casing with improved peelability

A tubular food casing based on cellulose, which on its inner surface has a coating which comprises lecithin and at least one of alginate, chitosans, and casein, has improved peelability from its contents.

A tubular packaging casing, in particular sausage casing, including a cellulose base layer and a barrier layer against steam and atmospheric oxygen, which is free from chlorine. The barrier layer includes random copolymer based on copolymerized vinyl monomers. The vinyl monomers correspond to the general formula CH.sub.2 .dbd.CR.sup.1 --X, wherein

Tubular packaging casing, particularly sausage casing, based on cellulose

A paper for fiber reinforcement in a base layer of a cellulose-based packaging film, in particular a tubular artificial sausage casing, or for tea-bags, wherein the paper includes alginic acid and/or an alginate which is substantially insoluble in water. A process for producing the paper which includes adding a water-soluble alginate to an aqueous suspension of cellulose fibers and precipitating the water-soluble alginate so as to form a substantially water-insoluble alginic acid or alginate.

Paper and fiber-reinforced packaging film and sausage products produced

The tubular packaging casing, in particular artificial sausage casing, based on cellulose contains a textile sheet-shaped structure which is surrounded by cellulose and gives the outside of the casing a sturdy texture.

Tubular packaging casing based on cellulose and having a textile-like

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

A tube, in particular sausage casing, is composed of mutually connected sections which at the connection point, prior to connection, possess cut edges extending approximately at right angles to the longitudinal axis of the tube and parallel to each other. The sections are connected by an adhesive tape extending around the outside of the tube. When the tube, possessing two folded edges extending parallel to each other, is flattened, the part of the cut edges of one section extending from a first folded edge of the other opposite folded edge is situated within the tube and the other part of this cut edge, which extends from the second folded edge back to the first folded edge, is situated on the outside of the tube. Parts of the cut edge of the other section are situated in reversed arrangement, firstly on the outside of the tube and then within the tube.

Tubular package casing composed of mutually connected sections

The cellulose-based product, in particular in the form of a film, contains in its wall a primary, permanent plasticizer of one or more crosslinked copolymers made from at least two components. One or more of these components are monomer units containing a terminal, ethylenically unsaturated, polymerizable group or compounds of maleic acid, or fumaric acid. A further component comprises units containing thermally crosslinked groups made from N-methylolamides of unsaturated carboxylic acids. A process is furthermore described for the production of this shaped product, in which the copolymer is metered into the viscose, and the N-methylolamide groups are thermally crosslinked with the cellulose.

Permanently plasticized, cellulose-based product

Disclosed is an artificial sausage casing comprising a fiber-reinforced, cellulose-based support tubing and a coating layer applied to the outer surface of the support tubing. The external coating layer comprises a casein crosslinked with glyoxal, and having sorbic acid radicals bonded by a salt-like linkage. The amount of casein in the external coating layer ranges from about 80 to 150 mg/m.sup.2, particularly from about 100 to 130 mg/m.sup.2. In a preferred embodiment, the inside surface of the support tubing is provided with a coating layer which serves either to improve the peelability and/or the adhesion between sausage meat and sausage casing or to provide compactness and gas-tightness.
