METHOD OF PRODUCING RuBisCO PROTEIN FIBERS

One or more ribulose-1,5-bisphosphate oxygenase protein fibers, produced by a process comprising the steps of:

• extracting ribulose-1,5-bisphosphate oxygenase protein from tobacco;
• feeding the extracted ribulose-1,5-bisphosphate oxygenase protein into an extruder;
• adding a plasticizer to the extruder forming a ribulose-1,5-bisphosphate oxygenase protein mixture;
• moving the ribulose-1,5-bisphosphate oxygenase protein mixture through one or more barrels of the extruder;
• heating the ribulose-1,5-bisphosphate oxygenase protein mixture to up to about 140 degrees C.;
• filtering the ribulose-1,5-bisphosphate oxygenase protein mixture with an about 20 μm filter;
• and
• exiting the ribulose-1,5-bisphosphate oxygenase protein mixture through an orifice to shape the mixture as it exits the extruder forming the one or more ribulose-1,5-bisphosphate oxygenase protein fibers.
