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
