(FR) PROTÉINE 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.

Des fractions de protéines de graines de chanvre sont fournies avec une applicabilité particulière pour former des émulsions stables pour la microencapsulation de composants à base de lipides. La fraction de protéine de graine de chanvre est extraite de la source de protéine de graine de chanvre par extraction alcaline aqueuse, suivie d'une séparation pour fournir une solution aqueuse de protéine de chanvre et des solides de source de protéine de chanvre résiduelle. La fraction de protéine de graine de chanvre est isolée de la solution aqueuse de protéine de chanvre par soit i) la précipitation de protéines de chanvre à partir de la solution aqueuse de protéine de chanvre séparée à ou au-dessus du pH isoélectrique et à une température inférieure ou égale à 70 °C, et la séparation des protéines précipitées pour produire une fraction de protéine de chanvre; ou ii) l'ultrafiltration de la solution de protéine de chanvre aqueuse séparée pour produire une fraction de protéine de chanvre ayant un poids moléculaire de 5000 Da et plus. Les fractions de protéine de chanvre isolées sont présentées pour former des émulsions stables avec des composants à base de lipide. La microencapsulation de composants à base de lipide est démontrée avec la fraction de protéine de graine de chanvre pour fournir des poudres microencapsulées ayant de bonnes propriétés de poudre.
