Abstract: The present invention relates to non-edible collagen casings for food products which do not have to be soaked in water or brine just before stuffing (ready-to-stuff casings), and the method for preparing them. More specifically, the invention refers to a preparation of a stabilized longlife non-edible collagen casing ready-to-stuff comprising a moisture amount between 27% and 50% by weight based on total casing weight and a salt amount between 2,5% and 30% by weight based on dry casing weight, wherein the salt comprises a salt from an organic acid and wherein the casing is packed.

Abstract: The invention provides a new collagen based technology. The invention provides a dry collagen powder as a precursor for the preparation of an homogeneous thermoplastic collagen-based composition, which may further comprise additives. The present invention relates also the use of said composition in the manufacturing of solid articles conformed according to plastic technology, and to the articles.

Abstract: A multi-perforated collagen film is provided on rolls or in the form of sheets for use as a food wrapping. The perforations and made by laser of substantially circular shape with an average ellipticity of less than 0.17 and the holes are spaced with respect to their nearest neighbors by 3 to 14 mm, thus allowing the escape of air or steam trapped between the film and the food wrapped in the film. The film still has sufficient mechanical strength and extensibility to be able to stand the food processing steps in the manufacture of cooked ham or in comparable operations under industrial conditions.

Abstract: The present invention relates to biodegradable protein based thermoset compositions formulated from a powder of a dry and finely ground protein material, from which the water has been thoroughly removed, an anhydrous and liquid alcohol and other optional additives. The inventions also relates to the method for obtaining these compositions in which the components are homogeneously mixed, under controlled conditions of temperature and moisture, to obtain a homogenous and shelf-cohesive mass, that can be shaped in any predetermined form by diverse molding methods, being readily set through the application of a certain amount of heat during a short period of time, which enables it to turn into a solid shaped body or article through a very simple process.

Abstract: The object of the invention is a multi-perforated collagen film provided on rolls or in the form of sheets, for use as a food wrapping in food industry, comprising perforations by means of laser of substantially circular shape with an average ellipticity of less than 0.17 and the holes being spaced with respect to their nearest neighbors by 3 mm to 14 mm, thus allowing the escape of air or steam trapped between the film and the food wrapped into said film, and said film still having sufficient mechanical strength and extensibility to be able to stand the food processing steps in the manufacture of cooked ham or in comparable operations under industrial conditions.

Abstract: The invention relates to a five-layered, biaxially oriented, shrinkable, sealable tubular film for the packaging and wrapping of paste-like foodstuffs, meat, or meat with bones and to the use thereof. The tubular film of the invention has an inner layer comprised of at least one copolyamide and at least one modified polyolefin, a layer of a modified polyolefin, a middle layer comprised of at least one homopolyamide and/or at lest one copolyamide and/or at least one copolymer of ethylene and vinyl alcohol and/or a modified polyolefin, a layer of at least one ethylene-vinyl alcohol copolymer, and an outer layer comprised of at least one polyolefin and/or at least one modified polyolefin. Such tubular films involve a significant improvement in the seal seam strength, in particular at low sealing temperatures, a high impermeability to oxygen and a comparable to markedly higher resistance to puncturing compared to prior art films.

Abstract: The invention relates to a coextruded, multilayered, biaxially oriented and weldable flat film for the production of welded tubular films and to the use thereof for wrapping and packaging foodstuffs. The inventive flat film has two weldable surface layers made of at least one copolyamide and at least one amorphous polyamide and/or at least one homopolyamide and/or at least one modified polyolefin.

Abstract: The invention relates to a biaxial stretch tubular film with five layers and which may be shrunk and sealed, for the packaging and covering of meat, meat with bones or paste-like foodstuffs and use thereof. Said tubular film comprises an inner layer made from a hot-sealing polyolefin and/or modified polyolefin, a core layer made from polyolefin and an outer layer made from at least one polyamide, whereby a further layer made from polyolefin and/or modified polyolefin is arranged between the inner layer and the core layer and between the core layer and the outer layer.

Abstract: The invention relates to a biaxial stretch tubular film with at least five layers and which may be shrunk and sealed, for the packaging and covering of meat, meat with bones or paste-like foodstuffs and use thereof. Said tubular film has the first four layers thereof, counting from the inside out, made from at least one polyolefin and/or modified polyolefin. A layer or several layers follow on said layers which are made from polyvinylidene chloride copolymer and/or polyamide and/or ethylene vinyl alcohol copolymer and/or polyolefin and/or modified polyolefin.

Abstract: Wreath-shaped edible collagen casings having a caliber between approximately 13 and 23 mm, a wall thickness of under 0.035 mm and an interior diameter of 100 mm to 350 mm, and a process for producing same. The wreath-shaped collagen casings are produced by treatment with ammonia and an aqueous coagulating agent immediately after extrusion, and a subsequent bordering process.

Abstract: A black edible flat film based on collagen with a wall thickness of up to 40 microns that comprises (a) a collagen substrate, and (b) at least one black pigment and wherein the concentration of said pigment is between 2% and 40% by weight based on dry collagen in order to meet the requirements of suppleness and non-transparency. These films are useful in the manufacture of foodstuffs having a black outer coating.
