Abstract: A beverage that may be consumed as a substitute for bovine milk or that may be stabily mixed with bovine milk in any proportion up to 10 days prior to consumption, and a process for making the same.Soy beans are ground in the presence of an acidified water solution that has a pH that optimizes protein extraction from ruptured bean cells and that insures that the amino acids so extracted will be in cationic form and therefore electrically associated with negatively charged ions supplied by the acidified water solution so that the protein is maintained in suspension and so that the solution is otherwise stabilized. The low pH also inhibits the enzymatic development of "painty", "fishy", and "beany" off-flavors.
