EXTRACTION AND mICRONIZATION OF EDESTIN FROM HEMP SEED

Abstract

Protein edestin extraction from hemp seed press cakes obtained after a cold press oil extraction process has been optimized at laboratory scale and verified in a pilot plant experiment. Subsequent water and brine extraction of the disintegrated hemp seed press cake was used to obtain the water-soluble albumin protein fraction and the brine-soluble globulin fraction -edestin. Isoelectric precipitation was used to obtain the proteins from the extraction solutions. New Carbon Dioxide Assisted Spray Nebulisation Drying (CASND) technology has been used to dry and micronize the protein concentrates and isolates. The protein powders were in form of hollow spheres with average particle diameter about 600 nm. The particles were characterized by the SEM method. The protein microparticulation allows to improve foaming and emulsifying properties and formation of long-term stable water dispersions.
