Prediction of Ash Content in Wheat Flour—Near-Infrared Method

VIEW METHOD

Objective
Ash content of flour is defined as the residue remaining after controlled incineration of the flour. It represents the mineral content of the flour, individual elements of which may exist in various forms in combination with other flour constituents. There is a very high correlation between flour ash and fiber contents (see reference), and it is likely that near-infrared (NIR) calibrations are associated with cellulosic components of bran fragments in the flour, rather than with the minerals themselves. See Method 39-00.01 for NIR guidelines.
