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.
