Uniformity, appearance and absence of physical defects became the basis of the selected
fruits. Then, the fruits were immediately transported to the Laboratory and covered in two kind of bags, namely MA-H film (permeability: 100.000 ml.day-1.m-2) as control and MA-A film (permeability: 2000 ml.day-1.m-2) combined with CO2 adsorbent (Ageless, Japan), CO2 adsorbent plus C2H4 adsorbent (Sensitech, United Technologies, U.S.A), and without adsorbent materials. A bag contained one pear. The packaged pears were then placed in a cold storage at 1 oC for 7 months
