Longans packaged in PF bags had the
lowest weight loss (0.7%) after storage at
10 C (Table 2), indicating that the pericarp
remained hydrated. Weight loss ranged from
3% to 6% for the other package treatments.
Although fruit in the MP or CL packages had
4% to 5% weight loss, they had slightly
longer shelf life than longans in the PF film
(Fig. 2; Table 2). This suggests that factors
in addition to RH (such as elevated CO2)
contributed to retaining visual quality and
low disease incidence up to 19 d for fruit
packaged in PF. Gas concentrations inside
MP or CL packages remained at ambient
levels, whereas steady state CO2 and O2
levels reached 15 mPa and 7 mPa, respectively
