- 4. A process as claimed in claim 1, wherein the pH value is adjusted while the extract is stirred.
- 5. A process as claimed in claim 1, wherein the pH value is adjusted by the addition of hydrochloric acid, acids of phosphorus, lactic acid or citric acid.
- 6. A process as claimed in claim 1, wherein the flocculate is eliminated by filtration, centrifuging or decantation.
- 7. A process as claimed in claim 1, wherein after the flocculate is eliminated, lecithin is added to the resulting extract in an amount of about 0.1% by weight.
