So, experimental data clearly show that addition ofk-carrageenan strongly affect the thermo-stability of k-carrageenan/
gelatin systems. It is reasonable to suppose that the basic reason for
this effect is formation of (bio)polyelectrolyte complexes and
transformation of supramolecular structure of materials under
study depending on their composition. The similar increase in the
melt temperature with increasingk-carrageenan (Pranoto et al.,
2007) or sodium alginate concentration (Derkatch et al., 2001)
was also observed for more concentrated gelatin gels.
