Devices for flour whiteness testing

Devices for determination of flour whiteness
The essence of the method consists in measurement of reflectivity of the compacted-smoothed surface of flour with the use of a photoelectric device.
The whiteness index is characterized by the zonal reflection coefficient in conventional units of the device.
Express method of whiteness determination is designed for rapid assessment of flour grade and technological process control in mills, as well as for input control of flour quality in bakeries.
