US Patent 10981948 Processes for increasing plant protein yield from biomass

A process for increasing protein yield from biomass (beans, oilseeds, cereals, nuts, rice, soybeans, bran, etc.), as well as, for reducing the amount of chemical and biological reagents used in the process, involves application of multiple hydrodynamic cavitation treatments of a biomass suspension or other combination of biomass with solvents and reagents—in the preparation, extraction, and processing or the biomass and proteins. The biomass suspension is preferably subjected to at least three cavitation treatments in order to facilitate the crushing of biomass, splitting of fibers, and rupture of cell membranes, thereby increasing the mass transfer surface area and intensifying the extraction of protein and lipids. At the stage of washing and neutralization the protein solution may be subjected to a fourth cavitation treatment to obtain the purified protein.
