Title
(EN) HEMP PROTEIN AND USE FOR MICROENCAPSULATION
(FR) PROTEINE DE CHANVRE ET SON UTILISATION POUR LA MICROENCAPSULATION
Abstract
(EN)
Hemp seed protein fractions are provided with particular applicability for forming stable emulsions for microencapsulating lipid based components. The hempseed protein fraction is extracted from hemp seed protein source by aqueous alkaline extraction, followed by separation to provide 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 protein fraction; or ii) ultrafiltering the separated aqueous hemp protein solution to produce a hemp protein fraction having a molecular weight of 5,000 Da and higher. The isolated hemp protein fractions are shown to form stable emulsions with lipid based components. Microencapsulation of lipid based components is demonstrated with the hemp seed protein fraction to provide microencapsulated powders with good powder properties.
