Konica minolta CR-14 Brochure

Whiteness Index

Check the whiteness of foods or raw materials.
Measure solids, pastes, or powders.

Whether a food's color is good or bad can influence consumer purchases. Since color variations
of white are especially obvious, it has become increasingly important to control color from raw
materials through the manufacturing process. Furthermore, there is a growing need to quantify
what effect storage during transportation has on the whiteness of a product.
