As compared with other polysaccharides, chitosan has several important advantages, including biocompatibility,
biodegradability, no toxicity and it has antimicrobial properties13. Systemic investigations have been reported on the
effects of chitosan on the mechanical properties and barrier characteristic of chitosan based edible coating.
Various studies on chitosan edible coating have been published but there are still very little work deals with the
variation degree of deacetylation of chitosan. Therefore, the objective of this study was to study the effects of
different DD and concentration of chitosan on weight loss and vitamin C loss. Additionally, the addition of TEA
emulsifier in the chitosan solution during coating process was also examined. Sensory analyses were conducted to
monitor the changes in appearance color, aroma, and texture.
