Industrial Process
Cold plasma pretreatment modifies biopolymer rheology to enhance extrusion efficiency and product functionality.
Atmospheric-pressure cold plasma (10-30 kV, 1-5 kHz) applied to starch/protein feedstocks for 30-180 sec reduces melt viscosity by 15-40%. Enables extrusion at 20-30% lower barrel temperatures (90-120°C vs. conventional 130-150°C) while mai…
