Patent ID: 8597712

Claim:
A method for removing isoflavones from a soy base, the method comprising: subjecting a mixture comprising water and soy beans to one or more of a grinding process and a milling process; maintaining the pH of the mixture comprising water and soy beans to a pH level of approximately pH 7,8 to pH 10, wherein the pH is maintained at least in part by blending one or more pH-controlling ingredients with the mixture; converting the mixture to the soy base by subjecting the mixture to one or more processes selected from the group consisting of sonic vibration and ultrahigh pressure homogenization; adjusting the pH level of the soy base to approximately pH 10.5 or greater; separating the soy base, using centrifugation, into a lipid phase substantially free from isoflavones and a serum phase containing isoflavones; adjusting the pH level of the serum phase to a level within the range of approximately pH 7 to pH 9; separating isoflavones from the serum phase; and mixing the lipid phase with the separated serum phase.
