What You Need to Know
Heating agar‑agar to 80–90 °C solubilizes the polysaccharide chains, allowing them to adopt random coils. Upon cooling to 35–40 °C, the chains form double‑helical aggregates that entangle into a three‑dimensional network, producing a gel whose rigidity depends on concentration. Flash‑gel accelerates this process by dropping the temperature to 0–5 °C within seconds, yielding fine micro‑gels with minimal syneresis.
