DSC thermograms generated for the five targeted food items are shown in Fig. 4A and B, for freezing and thawing, respectively. Latent heat released during freezing was represented by positive peaks (Fig. 4A), and during thawing, negative peaks were observed (Fig. 4B), due to absorption of latent heat (Le Reverend et al., 2009). Since, only water undergoes phase transition in this temperature range, the height of the peak is proportional to the available water in the system, for phase change (Hamdami et al., 2004b). For beefsteak and for concentrated orange juice, though both had approximately the same moisture content (~ 61% to 63% w.b.), heat flow peak of beefsteak was taller.
