Reformed casein micelles are produced from an aqueous solution or dispersion of commercially available processed casein by the sequential addition, over an extended period of time, of calcium ions and a soluble phosphate salt, after which the aqueous reaction medium is concentrated such as by ultrafiltration or diafiltration, to increase the level of casein micelles thereon and remove excess salts. The reformed casein micelles are used as a complete or partial replacement for fat in a variety of food products, particularly coffee whiteners. Coffee whiteners containing reformed casein micelles as a replacement for the fat component have functional and organoleptic properties equivalent to conventional coffee whiteners. |
