Protein-based material can be shaped by extrusion, roller milling,
or thermomolding (traditionally called thermoplastic processing
technologies). These methods are adapted to synthetic materials
for which shaping properties are fully known and fabrication
parameters are optimized. To transform proteins, we must consider
typical behavior, including relative thermal, mechanical, and
chemical sensitivity, and high viscosities of the soft materials
above the glass transition temperature. Process parameters such as
temperature, plasticizer concentration, and residence time must
thus be optimized for these natural raw materials.
