More Information
Summary: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.
