Decrease the water loss in the fruits (i.e., lower water vapour permeability values).
•
Decrease the O2 permeability (i.e., lower O2 permeability values) as a lower O2 concentration prolongs the shelf life by delaying the oxidative breakdown of the complex substrates (Farber et al., 2003), and reduce the production of ethylene, a key element of the ripening and maturation process (Lee et al., 1996 and Zagory, 1995).
•
Increase the shelf life of fruits, by increasing the lag-phase and generation time during the logarithmic growth phase of spoilage microorganisms (Farber et al., 2003 and Phillips, 1996), which is accomplished by keeping high CO2 permeability values.
•
Improve the mechanical resistance of the films/coatings in order to preserve their integrity as much as possible during the fruits’ shelf life.
