Freezing curves of fresh Barhi fruits during CF are shown in
Fig. 6(a). The curves represent the change of the fruit center
and its surrounding air temperature with time. From the figure
it is seen that the temperatures dropped during the first five
minutes from initial temperature of 21 C to 22.1 C and
91.8 C at the fruit center and its surroundings air, respectively.
From the freezing curves, it is shown that the temperature
of the fruit center dropped to 26.4 C after six minutes in
the freezer and about two minutes later it fell to 74.7 C. At
the end of ten minutes from the beginning of the freezing process
the temperatures dropped to 95 C and 107.8 C at
fruit center and its surroundings air, respectively.
