The results may be attributed to low
respiration and the growth of spoilage organisms (Jiang & Li, 2001).
Previous studies revealed that chitosan coating, by creating semipermeable
film on fruit surface, resulted in limiting fruit respiration
metabolism and fungal growth, thereby delaying the declines of
nutritional components such as soluble solids, ascorbic acid and
titratable acidity (Hagenmaier, 2005).
