Both the taste and the color scores of mango pulp fell
quickly during storage. Chitosan coating delayed the drop
in sensory quality, and extend the shelf life. Both the control
and the chitosan-coated, sliced mango fruit were still
commercially satisfactory after they had been stored for
three days. However, they had been stored for seven days,
the control became unacceptable for the market whereas
the good quality of the chitosan-coated sliced fruit was
retained. The sensory quality after three days did not vary
among the fruit treated with 0.5%, 1% and 2% chitosan but
the difference between the quality following treatment with
1% and 2% chitosan after seven days was significant (Table
1). Dong et al. (2004) reported that chitosan coating
improved the quality and extended the shelf life of peeled
litchi fruit. In this work, the chitosan coating on sliced
mango improved its quality and prevented surface cracking
and the leaking of juice.
