Calorimetric analyses were made using a TA4000 differential
scanning calorimeter (Mettler-Toledo, Greifensee, Switzerland) connected
to Starever 8.10 software (Mettler-Toledo). Heat flow calibration
was achieved using indium (heat of fusion ) 28.45 J/g). Temperature
calibration was carried out using hexane (mp)-93.5 °C), water (mp)
0.0 °C), and indium (mp ) 156.6 °C). Samples were prepared by
carefully weighing 10-15 mg of the fat extracted from the biscuits in
160 íL aluminum DSC pans, closed without hermetic sealing. An empty
pan was used as a reference. Samples were heated under nitrogen flow
(0.5 mL/min) at 60 °C for 15 min to destroy crystallization memory,
cooled to -80 °C, and then heated from -80 to 60 °C. The scanning
rate was 2 °C/min. The start and the end of melting transition were
taken as on-set (Ton) and off-set (Toff) points of transition, which are
the points at which the extrapolated baseline intersects the extrapolated
tangent of the calorimetric peak in the transition state. Results were
normalized to account for the weight
