Solvent-free production of protein-enriched fractions from navy bean flour using a triboelectrification-based approach

Conventional plant protein production methods involve the use of solvents, concentrated acids and alkali that can result in protein denaturation and loss of solubility, thereby reducing the quality and functionality of protein ingredients. A novel solvent-free tribo-electrostatic separation approach was developed for the production of high quality plant protein powders using navy bean flour as a model system. The process consisted of a …
