Aiming to control physiological activity of fruits, over
the past 40 years, considerable research has been done on
the use of edible coatings, as it is a cheaper and easier
method as compared to other preservation methodologies.
Edible coatings can create a modified atmosphere similar
to controlled atmosphere by modifying internal gas
composition retarding ripening and reducing decay [1,
2, 3, 4]. The modification of internal gas composition is
achieved through the regulation of moisture, oxygen,
carbon dioxide, lipid, aroma and flavour compounds
transfer in food systems [5, 6]. The use of coatings can
entrap aroma volatile compounds, thereby increasing their
concentrations [1, 4]. However, a certain degree of
oxygen and carbon dioxide permeability is necessary to
avoid anaerobic respiration, which would result in
physiological disorders and a rapid loss of quality. These
goals may be attained through the use of semi-permeable
coatings [7]
