Cooked rice samples were subjected to different freezing
conditions to obtain freezing rates ranging from slow to fast
freezing. Fig. 1 showed a typical temperature-time freezing curve
obtained experimentally for different freezing rates (0.09, 0.26,
0.33, 0.53 and 1.45 C/min). The characteristic freezing time tcf
ranged from 12.79 to 190.00 min, and the freezing rates ranged
from 1.45 C/min to 0.09 C/min, as shown in Table 1.
