While powders, grains and pastes, such as flour, sugar and cocoa, are largely dissimilar in their chemical and structural properties, they often share the common attribute of being opaque in nature and therefore benefit from similar color measurement techniques and instrumentation.
As with all opaque samples, best practices for color measurement dictate the use of directional 45°/0° reflectance geometry.
Many of HunterLab's spectrophotometers are versatile enough to accommodate most applications of color measurement.
