Measurement of Flour Whiteness.

A. W. Croes. Copyright 1961 by the American Association of Cereal Chemists, Inc. 

The whiteness of wheat flour was determined by means of photoelectric tristimulus measurements and substitution of the reflectance values A, B, and G in a newly derived equation for whiteness. This formula, which is in its most simple form W=G-A+B, simplifies the calculation of whiteness considerably, and, therefore, should be considered as useful for routine application. The results obtained were in complete accord with the visually estimated orders as found by means of the Pekar test. They can be considered as representative for visual judgments in average daylight.
