Cellulose is widely used in the production of synthetic sausage skins. Cellulosic material (e.g. wood) is mixed with alkaline solution to produce a dissolved cellulosic feedstock. This dope is then processed and extruded, and dried and rolled for the use as a sausage skin.
The cellulose fibers cloth is used as sausage casing. The cloth goes though precipitation for viscose purification and is then desulfurized by passing it through a Sodium Hydroxide (NaOH) bath. The caustic solution is prepared by mixing water and a concentrated solution of NaOH.
