Drying temperature was also a significant factor for lightness,
chroma and hue values (Table 4). Blueberries dried at 85 C had
higher values of lightness (15.69), chroma (3.50) and hue angle
(325.5) compared to those dried at 107 C (L* ¼ 15.07, C ¼ 3.12 and
H ¼ 323.2). Thus blueberries dried at 107 C were more bluish in
appearance than blueberries dried at 85 C.
