What You Need to Know
The high‑molecular‑weight polysaccharide undergoes extensive hydrogen bonding and chain entanglement as it cools, creating a dense, water‑retentive network. This gelation is reversible: heating above ~70 °C dissolves the network, while cooling restores it. The process is exploited in both traditional East Asian foods and modernist gastronomy.
