Development and optimization of a triboelectrification bioseparation process for dry fractionation of legume flours

A novel solvent-free tribo-electrostatic separation technique for the fractionation of legume flour has been explored with the aim of producing protein- and carbohydrate-enriched fractions from navy bean (Phaseolus vulgaris) flour as a model system. The process consisted of a fluidized bed flour reservoir, polytetrafluoroethylene (PTFE) tribo-charging tube, and a plate-type separation chamber. The optimization of the single-stage …
