The effect of cryogenic and ambient milling on the color of spice was investigated to determine its influence on spice quality. A Hunterlab Color Difference Meter and sensory analyses were used to determine if cryogenically milled spices were comparable to ambiently milled spices. Cryogenically milled spices are lighter in color than ambiently milled spices and untrained panelists were able to detect the differences (P ≤ 0.038).
