Various aspects of modified atmosphere packaging for storage of pears in perm-selective
polymeric film packages were investigated. The dynamics of respiration-permeation
interaction was analyzed with a view to facilitate self establishment of dynamic
equilibrium of gaseous composition within the package and external atmospheres
at a desired storage condition. By combining different polymeric films, three
types of laminated modified atmosphere packages (LF1, LF2, and LF3) were developed.
The modified atmosphere packaged pears were found to have retained freshness and
quality for a longer period of time. The shelf life of MA packaged pears could
be extended approximately 0.75 to 1.5 times in comparison to unpacked pears. The
performance of package type LF1 was found to be the best, whereas LF2 was found
to be the second best.
