Steady-state modelling of extrusion cooking employing response surface methodology

Abstract Extrusion cooking has been approached from the point of view of continuous screw reactor technology, applying a heuristic hypothesis to changes in biopolymer aggregate states. Engineering design variables, the nature of basic biopolymer reactions, mass-machine interactions, and problems in the modelling of product quality in extrusion cooking are discussed. Response surface methodology (RSM) and its applications are discussed in detail including its significance and limitations in the study of complicated experimental situations.
