Calcium fortification of bread dough
Calcium additives useful for fortifying baked goods, such as bread products, with calcium are disclosed. The calcium additives are particularly useful for fortifying leavened baked goods with calcium. Methods for preparing the calcium additives and using the calcium additives to fortify baked goods are also disclosed. Generally, the calcium additives comprise intimate admixtures calcium carbonate and an acid such as citric acid.
1. A dry calcium additive for use in a leavened bread product consisting essentially of an intimate admixture of: (1) calcium carbonate powder having a median particle size of about 12 to about 14 μm; and (2) an organic acid which is solid at ambient temperature; wherein the weight ratio of calcium carbonate powder to organic acid is from about 10:1 to about 75:1; and wherein the additive is substantially free of calcium salts of the organic acid.
2. The calcium additive of claim 1 wherein the median particle size of the calcium carbonate powder is about 13 μm.
3. The calcium additive of claim 2 wherein the acid is citric acid.
4. A dry calcium additive for use in a leavened bread product consisting essentially of an intimate admixture of: (1) calcium carbonate powder having a particle size less than about 30 μm; and (2) citric acid; wherein the weight ratio of calcium carbonate powder to citric acid is from about 10:1 to about 75:1; and wherein the additive is substantially free of calcium salts of citric acid.
