Description: The rising global food demand due to the increasing population has made sustainable food production obligatory. Animal-based food production necessitates more water and land resources than their plant-based alternative. Moreover, plant-based protein produces less greenhouse gas emissions. Current plant-based protein isolation through wet fractionation seems unsustainable due to its immense reliability on water, chemicals, and energy/heat. Dry fractionation techniques such as air classification and sieving have limitations due to physical properties such as particle density and size. Triboelectrostatic separation (TES) is a novel dry fractionation technique previously used in mineral and recycling industries. This technique can also be used for agro-particle segregation. In this investigation of TES, the impact of milling parameters and particle protein content on the separation characteristics (protein enrichment, mass yield, and protein separation efficiency) have been analyzed for yellow pea flour, faba bean flour, and yellow pea flour concentrates (protein and starch). A solid particle dispenser pneumatically charges the flour particles through a polyethylene(PE) tribocharger at an airflow rate of 2.1 m3/h. The electric field strength of the separator was configured at 100kV/m. Particle size distribution and scanning electron microscopy (SEM) have been used to analyze the pre- and post-separation of flour particles to validate the acquired results.
