A term used in relation to flour to indicate its mineral content. The higher the ash count, the more minerals are present in the flour, and vice versa. To calculate the ash count, a sample of the flour is incinerated and the remains (the "ash") are then weighed in relation to the original sample weight to calculate the ash count for that flour.
The ash count can serve as an indication of the degree of refinement of the flour since a flour from which most of the bran has been removed will have a lower ash count than one from which less bran has been removed. A flour with a high ash count will also be slightly darker than one with a low ash count because of the higher amount of bran.
