7.1 Total Ash
Determine the mineral content of the flour or evaluations of much outer layers (i.e. aleurone, pericarp, bran) are in the flour.
7.2 Flour Ash
The mineral content of the flour or an evaluation of much outer layers (i.e. aleurone, pericarp, bran, etc.) are in the flour. The approximate ash content of the endosperm is 0.30 - 0.35% and whole wheat is 1.5 - 2.0%. The percent ash from a 3-5 g sample of flour ignited and heated for 18 hours at 580EC in a muffle furnace. Percent ash = (weight of residue)/(weight of sample) x 100. Flour ash is corrected to a 14% moisture basis. AACC Method 08-01.
