Abstract
Annatto-caramel food colorant blends having a pH of about 9.1 to 10 that exhibit improved stability against precipitation and provide a rich brown color are particularly useful for use in RTE cereals. The blends are characterized by low ammonia contents (<0.05%). Methods for preparing low ammonia content caramel color solutions involve adding KOH to a caramel solution to a pH of >10, off gassing ammonia to reduce the ammonia content to <0.05%, and acidifying the caramel colorant to a pH of 6.5 to 7 to provide a treated low ammonia neutral aqueous caramel colorant. An aqueous annatto colorant having a pH of about 12.5 to 13.5 is admixed with the treated low ammonia neutral caramel solution in a solids weight ratio of about 1:1 to about 4:1.
