What You Need to Know
Polysaccharide hydrocolloids such as agar, carrageenan, pectin, gellan gum, methylcellulose, and konjac glucomannan undergo conformational changes upon heating or cooling, creating a three‑dimensional network stabilized by hydrogen bonds and ionic bridges. The gelation temperature, ion requirement, and concentration dictate the mechanical strength and reversibility of the gel, enabling precise textural control in culinary applications.
