Description
Spherification is a chemical technique that forms gelled droplets by cross‑linking alginate with calcium ions.
Technical
The process relies on the diffusion of Ca2+ ions into a sodium alginate solution, creating a cross‑linked hydrogel network. Precise concentrations of alginate (1–2 % w/v) and calcium chloride (0.1–0.5 % w/v) control shell thickness and firmness. Temperature and viscosity influence ion mobility and gelation time.
