juice or even to the juice centrifuged at 4000 rpm. Similar behav-ior is observed regarding to color removal (Fig. 3), suggesting that
chitosan coagulation is the main responsible for juice clarification.
The action of chitosan on color and turbidity reductions was also

of chitosan. Chater-jee et al. [1] observed a reduction of 73, 76, 72, and 61% of color using
