The present invention relates to processes for the treatment of dairy products and dairy process streams to produce lipids and substantially defatted protein streams. More specifically it relates to the use of near critical fluid extraction techniques to extract lipids from liquid dairy products and dairy process streams. Preferred solvents for use in the described near critical extraction techniques are ether based solvents that are partially miscible with water. A particularly preferred solvent for use in the invention is dimethyl ether.
L'invention concerne des procédés conçus pour le traitement de produits laitiers et de liquides laitiers à traiter pour produire des lipides et des liquides protéiques dégraissés. Plus précisément, elle concerne l'utilisation de techniques d'extraction de fluides quasi-critiques pour extraire des lipides à partir de produits laitiers liquides et de liquides laitiers. Les solvants préférés à utiliser dans ces techniques d'extraction sont des solvantsà base d'éther qui sont partiellement miscibles à l'eau.
