Patent ID: 7118776

Claim:
An acidic beverage composition, comprising; (A) a hydrated protein material having a combination of an inositol-6-phosphate content, an inositol-5-phosphate content, an inositol-4-phosphate content and an inositol-3-phosphate content of less than 8.0 μmol/g protein material prior to hydration, wherein the protein material, prior to hydration, is prepared by a process comprising: preparing an aqueous extract from a protein containing plant material, adjusting the pH of the extract to a value of from about 4 to about 5 to precipitate the protein material, separating the precipitated protein material and forming a suspension of the precipitated protein material in water, adjusting the pH of the suspension to a value of from about 3.5 to about 6 to form a partially solubilized protein material in water, adding a phytase to the partially solubilized protein material in water to form a phytase treated protein material, pasteurizing the phytase treated protein material at a temperature of 305° F.; and drying the protein material; and (B) a hydrated protein stabilizing agent comprising a polysaccharide hydrolysate and (C) at least one flavoring material comprising a fruit juice, a vegetable juice, citric acid, malic acid, tartaric acid, lactic acid, ascorbic acid, glucono delta lactone or phosphoric acid, wherein the acidic beverage composition has a pH of from 3.0 to 4.5.
