2.2.2. Instrumental color
Instrumental color was measured in a Spectrophotometer CM-
3500d (Konica Minolta Inc., Japan). Purée samples were filled
into a Petri plate taking care to exclude air bubbles, and placed
into the 30 mm aperture masks. Reflectance measurements
were made using geometry d/8 (diffuse illumination and 8◦
viewing angle) with the primary illuminant D65. In addition,
Hue (H) angle was calculated
