.MAP technology, which utilizes only the natural components
of air, has achieved public acceptance due to these
two trends. MAP has the advantages that synthetic chemicals
are not used, no toxic residue is left, and there is little
environmental impact, particularly if the plastic films used
can be recycled. Recent advances in the design and manufacture
of polymeric films with a wide range of gas-diffusion
characteristics have also stimulated interest in MAP
of fresh produce.
