Effects of Chitosan Treatments on the Clarity and Color of Apple Juice

Abstract
Acid‐soluble and water‐soluble chitosans as fining agents for apple juice were compared to conventional silica sol/gelatin/bentonite treatment. Both chitosans proved equally effective in reducing juice turbidity as compared to control treatments and slightly lighter juices resulted from chitosan treatments. Use of the one step chitosan treatment appeares an attractive alternative to conventional fining processes.
