Phospates by themselves are generally tasteless. Ames makes Amesphos which is just phospates. It is a white powder and doesn't taste like much. However they also make FAB B which is a beefy flavoring, MSG and phospates all mixed together into a powder. Butcher and losmos make a similar product to FAB B.
