ements of the extrusion process. Standard wet systems typically have 22-28 per cent residual moisture in the product, and even high moisture ( 40 per cent) extrusion has been developed.
While wet and high moisture extrusion offer some unique capabilities, the fact remains that the extruded product, with its high moisture content, must be dried for preservation. Spoilage microorganisms and pathogenic bacteria require water to survive and thrive, and so, unless other methods of preservation (such
