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.
Claims8
A method of producing an infant formula, the method comprising
- providing isolated beta-serum or isolated low-lactose beta-serum, the beta-serum or low-lactose beta-serum being isolated from cream after phase inversion of the cream during production of butteroil or anhydrous milk fat from cream, wherein the low-lactose beta-serum comprises less than 30% lactose on a dry weight basis, and
- combining the beta-serum or the low-lactose beta-serum with a source of protein, a source of lipid and a source of carbohydrate to produce an infant formula.
