CO₂-Based Gelation Process: Mixing Alginate, Calcium Carbonate, and Carbonated Water

Caption

Carbon dioxide creates the acidic environment necessary for calcium ions to link alginate chains, forming the hydrogel. However, the rapid release of CO₂ after gelation limits calcium ion availability, resulting in reduced crosslinking of the alginate chains.
