Several researchers studied on the kinetics of color changes of vegetables and fruits such as banana, apple, carrot and potato, kiwifruit, spinach pineapple puree, whole longan and longan without stone but no kinetics studied related with the color change during drying of longan flesh were found. Therefore, the aim of this research is to study the kinetics of color change of longan flesh during drying in order to predict color changes with time and drying air temperature.
