ABSTRACT
W pracy określono parametry przemian fazowych (temperatura przemiany szklistej, temperatura i ciepło krystalizacji, temperatura i ciepło topnienia) sacharozy oraz mieszanin sacharozy z dodatkiem jednowartościowych soli nieorganicznych (NaCl i KCl). Stwierdzono, że temperatura końcowa przemiany szklistej dla mieszanin sacharoza/KCl i sacharoza/NaCl obniżyła się w porównaniu do czystej sacharozy amorficznej tylko przy niskich poziomach aktywności wody, natomiast temperatura krystalizacji oraz temperatura topnienia tych mieszanin wzrosła w odniesieniu do czystej sacharozy amorficznej w całym badanym zakresie aktywności wody.

The paper defines the parameters of the phase transitions (glass transition temperature, the temperature and heat of crystallization, melting temperature and heat) of sucrose and mixtures of sucrose with monovalent inorganic salts (NaCl and KCl). The end temperature of glass transition for sucrose/KCl and sucrose/NaCl mixtures was found to have fallen in comparison with pure amorphous sucrose only at low levels of water activity, while the crystallization and melting temperatures of these mixtures were found to have increased in comparison with pure amorphous sucrose in the overall range of water activity investigated.
