Abstract
The present invention provides a process for fractionating biomass into its individual components. The process includes pretreating a biomass which may include mechanically altering the fibers and/or contacting the biomass with a solvent to provide a fluidized biomass. The pretreated fluidized biomass may be subjected to high frequency pulses and shear forces without denaturing one or more components of the biomass to provide a first liquid fraction and a first fractionated biomass. The first liquid fraction may then be isolated or separated from the first fractionated biomass. The biomass may be separated, isolated or purified into lignin, extractives for use in pharmaceuticals or nutraceuticals, cellulose, hemicellulose, and other sugars and proteins.
