Abstract: Processes for producing dairy products having lower levels of neutral lipids, and/or higher levels of polar lipids, by extraction using near critical carbon dioxide or dimethyl ether. These products may be used as ingredients in infant formulas. Infant formulas containing beta-serum are also claimed. “Beta-serum” means an aqueous dairy ingredient separated from dairy streams containing greater than 60% fat which have been through phase inversion from an oil-in-water to a water-in-oil emulsion, such as the serum produced during the production of butter oil.

Abstract: The present invention describes a method of enhancing clarity and/or stability properties of a protein-containing liquid or gel, comprising subjecting said liquid or gel to a pressure treatment of 100 Mpa or greater. Preferred proteins useful in the invention are whey protein isolates and whey protein concentrates. The methods of the invention may be used to improve the clarity and/or stability properties of fruit juices, vegetable juices, protein concentrates and protein syrups.

Abstract: 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.
