Abstract
The present invention provides a novel process for preparing fortified milk compositions from whole mammalian milk. The process of the present invention generally involves converting dried mammalian milk into a fats-enriched fraction, a protein-enriched fraction, and a carbohydrate-enriched fraction. The process comprises treating the dried milk with a fats extracting agent to provide a fats-enriched fraction, and a residual fraction comprising proteins and carbohydrates; separating said fats-enriched fraction from the residual fraction; and removing the fats extracting agent from the separated fats-enriched fraction to produce a dry fraction of oily, fats-enriched material and a fraction enriched in proteins and carbohydrates.
Claims4
A sterile fats-enriched fraction obtained by a process comprising:
- a) treating dried mammalian milk with a fats extracting agent at a pressure range of 2500-4500 psi (17237-31026 KPa), and temperature range of 40 to 75° C. to extract fats to provide a fats-enriched fraction, and a residual fraction comprising proteins and carbohydrates, wherein the fats extracting agent is supercritical carbon dioxide;
- b) separating said fats-enriched fraction from the residual fraction;
- and
- c) removing the fats extracting agent from the separated fats-enriched fraction to produce a dry fraction of oily, fats-enriched material, and a fraction enriched in proteins and carbohydrates,
- wherein the dried mammalian milk is freeze-dried/lyophilized milk.
A sterile fats-enriched fraction of mammalian milk, said fraction having components including immunoglobulins at levels 90% by weight or more of levels prior to sterilization.
