Abstract: The invention relates to an edible packaging film for foodstuffs, which contains cellulose, at least one protein and at least one filler. Bran, ground natural fibres, cotton linters, chitosan, guar meal, carob meal or micro-crystalline cellulose are preferably used as the fillers. The film is predominantly used to produce synthetic sausage casings.

Abstract: This invention relates to a method for producing proteinaceous shaped articles from globular proteins according to the NMMO method, and to proteinaceous shaped articles themselves that are made from globular proteins according to the NMMO method. According to the invention, a suspension consisting of aqueous NMMO and of these precrosslinked proteins is transferred into a spinning solution, whereby the suspension contains a polysaccharide and/or a polysaccharide is added to the extrusion solution. The spinning solution is extruded into a precipitation bath through a form tool and through an air gap. Afterwards, the shaped article is washed with an aqueous liquid without the use of solvents and is subsequently hardened using known crosslinking reactions. The produced solutions are processed for a diverse product-oriented processing, preferably on the basis of known wet and dry/wet spinning techniques, optionally in conjunction with multi-constituent spinning techniques.
