  • Publication number: 20190335800
    Abstract: 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.

  • Patent number: 8003813
    Abstract: A process for separating a blend of saturated and unsaturated fatty acids or saturated and unsaturated fatty acid alky esters into a first fraction enriched with the saturated fatty acids or saturated fatty acid alkyl esters and a second fraction enriched with unsaturated fatty acids or unsaturated fatty acid alkyl esters. When separating fatty acids, the process includes the steps of (a) saponifying a blend of long chain saturated and unsaturated fatty acids to form free fatty acids, (b) complexing the free fatty acids with urea, and (c) separating the urea complexed free fatty acids into a first fraction enriched with saturated free fatty acids and a second fraction enriched with unsaturated free fatty acids.
