Abstract
The effects of different packaging materials (including CPP, LDPE, HDPE, PP6, PP12, OPP and PO) on the changing of O2 and CO2 content in Red Fragrant Pear MAP during storage at different initial air conditions were studied in this paper. Gas composition was affected by respiration rate of pear and the permeability of packaging material remarkably. The results showed that OPP, LDPE and CPP were better for maintaining the desired atmosphere composition of O2, CO2, N2 during preservation of red fragrant pear. In addition, 100% N2 as initial gas was more suitable to preserve red fragrant pear than that with air or vacuum significantly.
