High value fruits namely, apple (cv. Royal
Delicious), guava (cv. Baruipur) and litchi (cv. Shahi) harvested
at their commercial maturity were considered for MA
packaging to enhance storage life. Polymeric films namely
LDPE, BOPP, PVC, PVDC of different thickness were used
for MA packaging study and various film characteristics such
as gas transmission rates, water vapour transmission rate,
clarity, strength and durability were evaluated. Mathematical
model was developed based on Arrhenius type equation to
predict gas transmission rate (GTR) and the developed model
was found to be very good fit with the mean relative deviation
modulus value quite less than 10 %. The GTR of the films
increased with the increase in storage temperature and the
magnitude of the increase varied with the film type and
thickness. Regression models have been suitably developed
to predict the oxygen transmission rate and carbon dioxide
transmission rate of selected polymeric films and combined
film laminates as a function of temperatures. Since, none of
the individual films could meet the gas transmission requirements
of MAP for selected fruits, two different films were
tailored to form laminates that sufficed the requirements for
prolonged storage with maintaining original quality.
