4. Conclusions
There was no difference in the measurement of the freezing
point (Tf) of tilapia fish burger using the cooling curves obtained
in two household refrigerator models and the differential scanning
calorimetry (DSC). The quick freeze function significantly
decreased the freezing time. The use of thermocouples, a datalogger
and domestic refrigerators was a simple, cheap and validated
method to obtain the cooling curves and important information,
such as freezing point, freezing times and freezing rates of high
moisture foods, such as fish burger.
