Dispersion of cellulose fibers and method of producing the same

A dispersion of cellulose fibers, a method of preparing the same and uses thereof. The dispersion is produced by providing a cellulose feedstock comprising cellulose fibers; by providing a mixture of an ionic liquid and a protic antisolvent for cellulose as a dispersion medium, the ionic liquid being selected from the group of protic salts of superbases capable of dissolving cellulose; and by mixing said cellulose feedstock into said dispersion medium so as to disperse the cellulose fibers therein to form a dispersion which is stable for at least 24 hours at room temperature. The dispersion can be used as an additive of cellulose pulps for making of fibrous products.

Food casing with permeability to smoke and water vapour and with improved transparency
12568979 · 2026-03-10 · ·

The present invention relates to a tubular, seamless, biaxially stretched, smoke-permeable and water vapour-permeable, colouristically neutral and transparent, single-layer food casing formed from a mixture including 50 to 95% by weight of aliphatic (co)polyamide, 3 to 40% by weight of at least one vinyl (co)polymer having units of N-vinyl-2-pyrrolidone and 1.5 to 7.0% by weight of at least one aliphatic diol and/or aliphatic polyol, based in each case on the weight of the mixture. The diol and/or polyol is homogeneously distributed in a matrix formed by the aliphatic (co)polyamide. The food casing is produced by an extrusion method with biaxial tube stretching and subsequent heat-setting. It is particularly suitable as synthetic sausage casing, especially for raw sausage, such as salami or mettwurst.

Edible cellulosic casings and compositions, and methods of formation

Edible cellulosic casings comprise cellulose and at least one modifier comprising at least one polysaccharide. The at least one modifier is substantially evenly distributed with the cellulose throughout a casing material of the edible cellulosic casing. A composition useful for an edible cellulosic casing comprises regenerated cellulose and at least one non-cellulose hydrophilic polysaccharide dispersed in the regenerated cellulose. The regenerated cellulose composes at least 50 wt. % of the composition. A method for forming an edible cellulosic casing comprises forming a cellulose solution and forming a modifier solution comprising at least one polysaccharide dissolved therein. The modifier and cellulose solutions are mixed to form a mixture from which the edible cellulosic casing is made. Edible cellulosic casings, as disclosed, may be consumed along with an encased foodstuff or other material for ingestion.
