New polysaccharides have recurring units I or a salt thereof. ##STR1##

Polysaccharides, process for their preparation and their use

New polysaccharide carbonates are produced by acylation of polysaccharides with carbonic acid esters and have degrees of substitution of preferably 0.5 to 3.

Carbonic acid esters of polysaccharides and a process for their

Cellulase-free heteropolysaccharides, more especially xanthan, are obtainable by treatment at special pH values, heat treatment, optionally cooling, neutralization and, optionally, subsequent precipitation in a high-turbulence precipitation bath.

Process for the production of heteropolysaccharides having improved

Tubular packaging casing, in particular a food-stuffs casing of regenerated cellulose, which contains an internal coating of film-forming plastic resins, which contains 10 to 200 mg of a protein coagulant per m.sup.2 of internal coating having at least one COOH-group or a salt thereof.
