Hemp seed protein fractions are provided with particular applicability for forming stable emulsions for microencapsulating lipid based components. The hemp seed protein fraction is extracted from a hemp seed protein source by aqueous alkaline extraction, followed by separation to provide a aqueous hemp protein solution and residual hemp protein source solids. The hemp seed protein fraction is isolated from the aqueous hemp protein solution by either i) precipitating hemp proteins from the separated aqueous hemp protein solution at or above the isoelectric pH and at a temperature no greater than 70° C., and separating the precipitated proteins to produce a hemp seed protein fraction; or ii) ultrafiltering the separated aqueous hemp protein solution to produce a hemp seed protein fraction having a molecular weight of 5,000 Da and higher. The isolated hemp seed protein fractions form stable emulsions with lipid based components and form microencapsulated powders.
A microencapsulated product of microcapsules, wherein the microcapsules comprise:
A method of extracting a hemp protein fraction comprising:
A hemp protein fraction for use in microencapsulating a lipid based component, wherein the hemp protein fraction is obtained by alkaline aqueous extraction from a hemp seed protein source such that the hemp protein is water soluble under alkaline conditions and is capable of forming a stable emulsion with the lipid based component.
