TPS based biocomposites can be processed, in a one-step process,
via an extrusion-cooking (Janssen and Moscicki, 2009).
Generally speaking, extrusion-cooking of vegetable raw materials
(technique widely used in food sector) consists in the
extrusion of grinded material at baro-thermal conditions.
With the help of shear energy exerted by the rotating screw
and additional heating by the barrel, the food material is
heated to its melting point or plasticating-point
