In current food industries’ practice, two principal color measurement techniques are used: Colorimetry and Spectropotometry.
Colorimetry is the technique which quantifies color by measuring three primary color components of light which are seen by the human eye, specifically, red, green and blue (also referred to as “RGB”).
Spectrophotometry, a scientific “step up” so to speak, is presently the most precise and accurate technique for the measurement, formulation and quality control of desired colors in prepared food products.
