During cold treatment in the walk-in refrigerated
room, pulp temperatures were similarly monitored
for each box of infested fruit and at least
one box of quality fruit. Air temperatures were
monitored near the middle of the room (on the
wall) and on top of the stack of boxes. A sample
temperature profile showing a transient temperature
spike to ca. 4.2–5.0°C and return to the
treatment temperature is shown in Fig. 1.
