Abstract. Ash refers to the inorganic residue remaining after either ignition or complete oxidation of organic matter in a food sample. Determining the ash content of a food is part of proximate analysis for nutritional evaluation and it is an important quality attribute for some food ingredients.
Ash content is a widely accepted index of refinement of foods, such as wheat flour or sugar. Since the mineral content of the bran is about 20 times that of the endosperm, the ash test is reliable indicator of the efficiency of which the separation of bran and germ from the rest of the wheat kernel.
American procedure (ASTM, D 3174) Ash content determination in coal relies on weighing, with a high accuracy, about one gram of dry coal in a crucible and putting the sample into a cold furnace.

Ash content determination is widely used in the flour milling industry as a quality measure for flour extraction. When ash is too high in flour, this indicates too much contamination of flour with bran (outer covering of wheat kernel).
