Effects of calcium infiltration and chitosan coating on storage life and quality characteristics during storage of papaya (Carica papaya L.)
Mature green stage (Index 2) papaya cv Eksotika II fruits were treated either with 2.5% calcium chloride infiltration, 0.75% chitosan coating, calcium infiltration at 2.5% then subsequently with chitosan coating at 0.75% or untreated fruits as the control. The fruits were then stored at 13±1°C for 3...
