rheological characteristics, nontoxicity, etc. These properties depend on
the type of material used, its formation and application. The benefit of us-
ing selective films seems to be the reduction of water loss, which is one of
the most important factors in the deterioration of highly perishable com-
modities. The films provide protection against moisture loss and maintain
an attractive appearance of the produce. Specific coating materials used
commercially for different fruit crops are enlisted in Table 16.1.

APPLE WRAPS
Apple based wraps are made from apple puree with various concentrations
of fatty acids, fatty alcohols, beeswax and vegetable oil and have a color
of apple sauce. These wraps are excellent oxygen barriers, particularly at
low to moderate relative humidity, but are not very good moisture barriers
unless lipids are added. Wrapping apple based films formed around apple
pieces significantly reduced moisture loss and browning in cut apples, in-
creased the intensity of apple flavor, and maintained the texture during
12-days storage period at 5 °C (McHugh and Senesi, 2000).
