Fig. 8 shows the parameters of L* (lightness), a* (redness: green to
red), b* (yellowness: blue to yellow), h (hue value, color angle,
Eq. (4)), C* (chroma value, color saturation, Eq. (5)) and ΔE (total
color change, Eq. (6)) as a function of the homogenization pressure.
Fig. 9 shows the evolution of these parameters throughout the
60 days of storage at 25 °C.
