Abstract
Diferencijalnom motridbenom kalorimetrijom (DSC) određen je utjecaj modificiranih škrobova na termofizička svojstva pilećeg surimija. Uzorci pilećeg surimija pomiješani su s modificiranim škrobom izoliranim iz tapioke 1 (MTS1) (w = 5 i 10 %), modificiranim škrobom izoliranim iz tapioke 2 (MTS2) (w = 5 i 10 %) i modificiranim škrobom izoliranim iz ječma (MBS = 5 i 10 %). Izmjerene su temperature početka denaturacije (T0), temperature denaturacije (Tp), temperature završetka denaturacije (Te) te entalpije denaturacije (ΔH). Diferencijalna motridbena kalorimetrija (DMK) pokazala je pomak temperatura denaturacije (Tp) miozina i aktina na više vrijednosti u uzorcima pomiješanim s MBS te na niže temperature u uzorcima pomiješanim s MTS1 i MTS2. Entalpija denaturacije miofibrilarnih proteina pilećeg surimija pokazala je povećanje s porastom masenog udjela MBS, odnosno smanjenje s porastom masenog udjela MTS1 i MTS2. Povišenje temperature denaturacije i entalpije u uzorcima upućuje na moguće interakcije između miofibrilarnih proteina i modificiranog škroba izoliranog iz ječma.
Abstract (english)
Differential scanning calorimetry (DSC) was used to determine influence of modified starches on thermophysical properties of myofibrillar protein concentrate (MPC). Samples of chicken surimi were mixed with tapioca modified starch (MTS1) (w = 5 and 10%), tapioca modified starch (MTS2) (w = 5 and 10%) and barley modified starch (MBS) (w = 5 and 10%). Onset temperature of transition (To), peak thermal transition (Tp), endset temperature of transition (Te), and denaturation enthalpy (ΔH) were evaluated. Differential scanning calorimetry (DSC) revealed a shift in peak thermal transition temperature (Tp) of myosin and actin to higher temperature in samples mixed MBS and to the lower temperatures in samples mixed with MTS1 and MTS2. Transition enthalpies for myofibrillar proteins showed increase with incense of mass fraction of MBS and decrease with the increase of mass fractions of MTS1 and MTS2. Increase of transitions temperatures and enthalpies in samples indicates possible interactions between myofibrillar proteins and modified barley starch (MBS).
