Chitosan can be used as a clarifying agent in fruit juices. Clarification
of fruit juices with chitosan has been attempted by Soto-Peralta
and others (1989), Chatterjee and others (2004), andRungsardthong
and others (2006). Chatterjee and others (2004) applied watersoluble
chitosan, hydrolyzed with 7% acetic acid, for clarification
of apple, grape, lemon, and orange juices. Chitosan (2% dissolved
in water) was more effective in reducing the turbidity of
juices than bentonite and gelatin. The appearance and acceptability
of the juices (measured on a 9-point hedonic scale), after chitosan
treatment, significantly increased. Rungsardthong and others
(2006) compared the effectiveness of chitosan prepared from Absidia
glauca var. paradoxa (fungal chitosan; DD = 86%) with that
prepared from shrimp shells as fining agents for apple juice.
