ANALISIS KONSENTRASI GAS SESAAT DALAM KEMASAN MELALUI LUBANG BERUKURAN MICRO UNTUK MENGEMAS BUAH SEGAR DENGAN SISTIM KEMASAN ATMOSFIR TERMODIFIKASI
ABSTRACT: Fruits can suddenly
loose its quality, thus it needs a good packaging material with a suitable
permebiality, so that gas exchange inside the packaging normally take place
through film packaging. The increasing of permeability on plastic film can be
done by giving perforation or a whole on its surface. This research is intended
to find out the rate gas exchange through film packaging. In packaging system
with modified atmosphire. The result of this research shows that the use of
perforation with micro size (50-200 µm) can increase the rate of gas transmission
of plastic film toward O. Identification on packaging material which is used
reveal that plastic permeability without perforation toward O2 is less than
plastic permeability with 10 perforation. Gas equilibrium for 10 perforation
packaging resulted on day 21 with gas concentration 0,001% (O2) and 0,000798 %
(CO2). The approach by using mathemathic model is done to find out gas
concentration inside the packaging during the storage. The model which is
developed by Gonzales et al. (2008) nearly close to the result as the
observation conducted.
