Description
Sub-techniques of spherification and gelification manipulate polysaccharide–cation interactions or protein denaturation to create edible structures.
Technical
Spherification relies on ionic crosslinking between alginate and calcium ions, forming a thin gel shell around a liquid core. Gelification processes—using gelatin, agar, or pectin—depend on protein or polysaccharide denaturation and aggregation, with temperature, pH, and concentration controlling the final texture.
