PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
A process that uses agar and carrageenan polysaccharides to form thermally reversible gels.
Origin: Japanese, Korean, Chinese, Irish, European, American (Traditional to modern) — East Asia, Europe, North America
See full technique reference →Agar dissolves at 85–95 °C, forming a hydrogen‑bonded network upon cooling to 20–25 °C, while carrageenan dissolves at 70–80 °C and crosslinks via cations (K⁺ or Ca²⁺) to create brittle or elastic gels. Gel strength increases linearly with concentration and is influenced by ionic strength, pH, and sugar content.
Primary Reaction
Formation of a three‑dimensional polysaccharide network through hydrogen bonding (agar) and ionic crosslinking (carrageenan).
