Color Measurements in Seasonings
Measurements were performed on vinegar, ketchup, sauce, and mayonnaise. The CIE xy chromaticity diagram and UCS Lab color space diagram shown are based on the spectral data using light source C and a 2-degree view field. The xy chromaticity diagram indicates chromaticity on x and y coordinates (color phase and color saturation). The closer to the center of the chromaticity diagram, the lower the color saturation. The L* scale at the left of the Lab color space diagram indicates the brightness value in the range from 0 to 100. The color saturation decreases from the edge of the color space diagram toward the center.
* Transmittance measurements on vinegar. Reflectance measurements on other seasonings.
