Abstract: A process for producing a bio-inactive and shelf stable biomass matter derived from bioactive biomass feedstock includes processes that can be performed in an effective way with equipment that does not require large expenditures. The biomass feedstock may be dewatered and then stabilized to prevent degradation. The stabilized biomass may then be back blended with a dried back blending biomass having a water concentration of less than 10% and a particle size that produces back blended biomass that can be effectively processed by controlled agitation drying wherein the thickness is maintained at less than 100 mm while an airflow is formed over the back blended biomass and shear mechanical energy is imparted. The entire process may be performed in less than 12 hours to produce a shelf-stable dried biomass.

Abstract: A method and system for the treatment of a biomass stream to separate organic extracts/biomolecules (such as proteins, lipids and/or carotenoids) from the biomass stream, wherein the water content of the biomass stream is decreased by bringing the biomass stream into contact with a compressed liquefied gas solvent, to create a low-water content biomass stream and introducing the low-water content biomass stream to an extraction apparatus that recovers one or more organic products with little or no measurable solvent residue.

Abstract: A pretreatment for use with systems and methods for extracting and separating a bio-molecule, such as a lipid and/or a protein, from a biomass includes the step of contacting the biomass with a drying gas to substantially dewater the biomass to 20% water content by mass or less. Such pretreated biomass, mixed with one or more compressed liquefied gas solvents, may then be introduced into individual filter cells in a rotary pressure filter to separate lipids from proteins.
