Abstract

Effects of chitosan coating on respiration rate and internal gas composition of 'Fuji' apple and 'Satsuma' mandarin were investigated and compared to wax emulsions and two commercial coating materials. Chitosan coating reduced respiration rate significantly (p<0.05) in 'Fuji' apple and 'Satsuma' mandarin compared to uncoated and other coating materials. Chitosan coating on 'Fuji' apple showed the highest CO2 and the lowest O 2 concentration in the internal gas composition at 5°C but showed no differences compared to other coating materials at 20°C. 'Satsuma' mandarin showed significantly high CO2 concentration in chitosan coating at 20°C but there were not significant differences among coating materials in CO2 and O2 composition at 5°C.
