Lightness value of water stress and no water stress tomato as shown in Fig. 2 decreased during 16 days storage.
The value were slightly different for no water stress and water stress tomato in all temperatures and storage time.
Lightness value of water stress tomato were higher than no water stress tomato except in 10 °C storage. Yellowness
(b*) value of no water stress and water stress tomato were not significantly different in all temperatures and storage
time. During 16 days of storage, yellowness value of both water stress and no water stress tomato decreased
continuously until the end of storage. Another studies such as Camelo and Gomez (2004) and Arias et al., (2000)
stated that b* values changed insignificantly during ripening and the value were higher at the pink-light red stage.
This may be related to the fact that 9-carotenes (pale-yellow color) reach their highest concentration before full
ripening, when lycopene (red color) and β-carotene (orange color) achieve their peaks (Fraser et al., (1994); Choi et
