Effect of extraction parameters on the chemical structure and gel properties of κ/ι-hybrid carrageenans obtained from Mastocarpus stellatus
Extraction parameters (temperature, pH, duration) and alkaline pre-treatment duration have
been systematically varied in the aim of exploring their impact on both chemical structure
and gelling properties of carrageenan biopolymers obtained from Mastocarpus stellatus
seaweeds, collected on the Northern coast of Portugal. Increasing the alkaline pre-treatment
duration PT leads to κ/ι-hybrid carrageenans containing less sulphate groups and biological
precursor monomers. As a result, gel properties in the presence of KCl are improved as …
