Wet fractionation techniques, which are conventional plant protein production methods, reduce the quality and functionality of protein ingredients. Tribo-electrostatic separation, which is a dry fractionation technique, can be a suitable alternative. In this study, the protein concentration potential of soybean powder through tribo-electrostatic separation was evaluated. Metal charging material showed a tendency to have a higher protein content and lower recovery than plastic. The charger length and applied voltage of the electrodes did not show any noticeable changes and trends. Nitrogen (N2) gas and charger internal diameter were related to the gas velocity in the pipeline, and as the gas velocity increased, the protein content increased and the recovery decreased. The removal of fat had a positive effect on separation efficiency. The increase in the protein concentration from full-fat soybean powder was 1∼4%, whereas that of de-fatted (about 30%) soybean power was 4∼6%. In conclusion, the removal of fat, which affects particle aggregation and particle dispersion, is considered an important condition for protein concentration through tribo-electrostatic separation.
