摘要:
A food casing is described with or without flat reinforcement insert and a smoke-permeable costing, preferably of protein, cellulose or acrylic. The insert is preferably a consolidated nonwoven or spunbonded nonwoven, a woven fabric, loop-formingly knitted fabric, laid fabric or loop-drawingly knitted fabric. The flat strip is glued to form a tube using a smoke-permeable gluing medium, preferably blood, plasma, protein, or other proteins. The food casing is preferably used as artificial sausage casing or cheese casing.
摘要:
A film-forming collagen concentrate is provided containing at least 18% by weight dry matter. At least 50% by weight of the protein of a homogeneous suspension produced from the concentrate in a 0.15 molar aqueous sodium dihydrogenphosphate buffer having a pH of 7 and a calculated dry matter fraction of 0.5% by weight may be separated as sediment by 15 min centrifugation at 1780 RFC and 15° C. A process is also disclosed for producing a collagen-concentrate-containing food casing that includes (a) producing an aqueous collagen mass; (b) concentrating the aqueous collagen mass until it has a solids fraction of 18% by weight or more; (c) admixing the concentrate with dilute acid to obtain a (co)extrudable or castable collagen mass; (d) coextruding or casting the collagen mass to from a casing; (e) solidifying the casing and, optionally, (f) drying the casing.
摘要:
The invention relates to a tubular cellulose-based food casing, the internal and/or external face of which is provided with an impregnation or coating made of blood albumin and/or a mixture of collagen fibers and collagen hydrolysate that improves cling of the casing to the food or renders the casing virtually resistant against cellulytic enzymes. The invention also relates to a method for producing such impregnated food casing and the use thereof as an artificial sausage casing.
摘要:
The invention relates to a single- or multilayer, flat or tubular food casing incorporating a carrier based on a water-insoluble, thermoplastic polymer, a polymer of animal or vegetable origin or regenerated or precipitated cellulose, and a coating. The carrier is a textile material or a film or a combination thereof. The coating includes binder and particulate foods with a mean particle size of 60 μm or more, optionally also food additives such as food colorings and liquid smoke. It additionally relates to a process for producing the casing and to its use as an outer casing for fish, meat and sausage products.

摘要:
An edible food casing, i.e. a casing which can also be consumed, is disclosed which is based on non-heat-coagulating protein which is mixed with a heat-coagulating agent. The non-heat-coagulating protein is preferably collagen and/or a collagen derivative, whereas the heat-coagulating agent is preferably protein from hens' eggs, blood plasma, whey isolate, globin and/or myosin. The casing can be produced as a flat film. It can also be generated immediately in the production of the food product, in particular in sausage production, using a coextrusion ring die around an extruded food. The casing is solidified by treatment with an aqueous salt solution, if appropriate also using transaminase. The food product is preferably a bratwurst.
摘要:
The invention relates to a single-layer or multilayer, flat or tubular food casing having a support based on a water-insoluble thermoplastic polymer, a polymer of animal or plant or chemical origin, or regenerated or precipitated cellulose, an adhesion layer (binder layer) firmly bound to the support and a transferable layer situated thereon. This transferable layer comprises particulate foods having a mean particle size of 60 to 800 μm, if appropriate also food additives such as food dyes and liquid smoke. In addition the invention relates to a method of producing the casing and use thereof as wrapping of meat and sausage products, fish products, cheese, baked goods and confectionery.
