Description
Gelation of plant polysaccharides forms firm gels under specific temperature, concentration, ionic, and pH conditions.
Technical
Agarose forms triple‑helical networks upon cooling, carrageenan aggregates helicoidally in the presence of K⁺ or Ca²⁺, and pectin cross‑links via calcium or acid‑mediated gelation; these structures yield predictable gel strength and stability for culinary applications.
