Cryoprotective Effect of Polydextrose on Adriatic Surimi

The cryoprotective effects of polydextrose in surimi samples mixed with sodium tripolyphosphate (w = 0.3%), and different mass fractions of polydextrose (w = 1-10%) were investigated by use of differential scanning calorimetry (DSC). Surimi was prepared from Adriatic pilchard (Sardina philchardus), quickly frozen and stored for 24 months on -25 °C. Onset temperature of transition (To), peak thermal transition (Tp), and endset temperature of transition (Te), and denaturation enthalpy (Δ H) were evaluated Enthalpic changes for myofibrillar proteins were always endothermic in nature. Differential scanning calorimetry (DSC) revealed a shift in thermal transition temperature of myosin and actin to higher temperature as the mass fraction of polydextrose increases. Since the enthalpy is directly related to amount of native proteins, higher values of Δ H indicates to the higher cryoprotective effects of polydextrose.
