Co-Extrusion Gel

Co-Extrusion Gel

Co-extrusion is a completely automated process for producing sausage with a casing formed by gel. A uniform thin layer of gel is applied to the outside of the sausage just as it is being formed. As it passes this salt bath, this layer acquires the necessary firmness and strength for further processing. When compared to conventional methods, cost savings are significant, and food safety aspects are unique. Viscofan’s co-extrusion gel is available in both Collagen and Alginate.
