Description
Thermo‑reversible gels form when gelling agents are heated above a critical temperature and then cooled, creating a solid network that melts upon reheating.
Technical
Polysaccharide and protein chains undergo temperature‑induced conformational changes, forming helices or double‑helical structures stabilized by sulfate groups or calcium cross‑links. Upon cooling, these helices lock into a three‑dimensional network, while heating disrupts hydrogen bonds and melts the gel. The process is reversible, allowing precise control over texture in food systems.
