Claims
- 1. An improved chemical leavening base for use in leavened compositions which comprises a baking bicarbonate intimately admixed with at least one food grade, essentially water insoluble salt or oxide of a metal selected from Periods 3 or 4 of the Periodic Table of the Elements and having an atomic weight of less than 66 such that the carbonate acts as a carrier for the insoluble salt or oxide which is essentially uniformly distributed throughout and on the surface of the bicarbonate.
- 2. The composition of claim 1 wherein the leavening base contains from about 0.10% to about 2.0% by weight of the insoluble salt or oxide.
- 3. The composition of claim 1 wherein the baking bicarbonate is an alkali metal bicarbonate, ammonium bicarbonate or a mixture thereof.
- 4. The composition of claim 1 wherein the insoluble salt or oxide has a particle size within the range of from about 1 to 50 microns.
- 5. The composition of claim 1 wherein the metal is a member selected from the group consisting of magnesium, aluminum, silicon, calcium, titanium, manganese, and zinc.
- 6. The composition of claim 1 wherein the insoluble salt is a salt of a fatty acid, carbonate, phosphate or silicate.
- 7. The composition of claim 1 wherein the insoluble oxide is zinc oxide, titanium dioxide, magnesium oxide, silica, or silica gel.
- 8. An improved chemical leavening system for use in leavened baking compositions which comprises at least one chemical leavening acid and at least one chemical leavening base which comprises a baking bicarbonate intimately admixed with at least one food grade, essentially water insoluble salt or oxide of a metal selected from Periods 3 or 4 of the Periodic Table of Elements and having an atomic weight of less than 66 such that the carbonate acts as a carrier for the insoluble salt or oxide which is essentially uniformly distributed throughout and on the surface of the bicarbonate.
- 9. The composition of claim 8 wherein the leavening base contains from about 0.10% to about 2.0% by weight of the insoluble salt or oxide.
- 10. The composition of claim 8 wherein the baking bicarbonate is an alkali metal bicarbonate, ammonium bicarbonate or a mixture thereof.
- 11. The composition of claim 8 wherein the insoluble salt or oxide has a particle size within the range of from about 1 to 50 microns.
- 12. The composition of claim 8 wherein the metal is a member selected from the group consisting of magnesium, aluminum, silicon, calcium, titanium, manganese, and zinc.
- 13. The composition of claim 8 wherein the insoluble salt is a salt of a fatty acid, carbonate, phosphate or silicate.
- 14. The composition of claim 8 wherein the insoluble oxide is zinc oxide, titanium dioxide, magnesium oxide, silica, or silica gel.
- 15. A method of preparing an improved baking composition rich comprises intimately admixing a chemical leavening base comprising a baking bicarbonate with at least one food grade, essentially water insoluble salt or oxide of a metal selected from Periods 3 or 4 of the Periodic Table of the Elements and having an atomic weight of less than 66 such that the carbonate acts as a carrier for the insoluble salt or oxide which is essentially uniformly distributed throughout and on the surface of the bicarbonate and adding the resulting treated chemical leavening base to the components of the baking composition.
- 16. The method of claim 15 wherein the leavening base contains from about 0.10% to about 2.0% by weight of the insoluble salt or oxide.
- 17. The method of claim 15 wherein the baking bicarbonate is an alkali metal bicarbonate, ammonium bicarbonate or a mixture thereof.
- 18. The method of claim 15 wherein the insoluble salt or oxide has a particle size within the range of from about 1 to 50 microns.
- 19. The composition of claim 15 wherein the metal is a member selected from the group consisting of magnesium, aluminum, silicon, calcium, titanium, manganese, and zinc.
- 20. The method of claim 15 wherein the insoluble salt is a salt of a fatty acid, carbonate, phosphate or silicate.
- 21. The method of claim 15 wherein the insoluble oxide is zinc oxide, titanium dioxide, magnesium oxide, silica, or silica gel.
- 22. The method of claim 15 wherein the admixing is carried out for a period of from 10 minutes to 2 hours.
- 23. The method of claim 15 wherein the admixing is a dry operation.
- 24. The method of claim 15 wherein the admixing is carried out in the presence of a non-aqueous fluid.
- 25. The method of claim 24 wherein the non-aqueous fluid is an alcohol.
