Abstract

Carbonated water facilitates the gelation of alginate and CaCO₃ solutions. The rapid release of CO₂ from the hydrogels after gelation resulted in a faster pH increase, lower amount of CaCO₃ dissolution, and lower crosslinking degree. The CO₂ release behavior, i.e., “post-gelation condition,” affects the degree of crosslinking, an essential parameter for determining hydrogel properties.
