  • Title: The effect of sucrose on unfrozen water and syneresis of acidified sodium caseinate-xanthan gels.
    Author: Braga AL, Cunha RL.
    Journal: Int J Biol Macromol; 2005 Jul; 36(1-2):33-8. PubMed ID: 15913757.
    Abstract:
    The influence of the ingredients of acidified Na caseinate-xanthan-sucrose gels on thermophysical properties and syneresis of the gels was studied. Sucrose concentration affected all of the gel equilibrium properties and the rate of syneresis. The positive effect of sucrose on syneresis and unfrozen water (UFW) values was attributed to different effects. The amount of UFW was governed mainly by the colligative properties of sucrose whereas the equilibrium syneresis behaviour was associated with the changes in network dynamics caused by the kosmotropic properties of sucrose. The latter could enhance xanthan-sucrose association or favour xanthan-protein interactions.
