What You Need to Know
Agarose polymers form double helices upon cooling below 40°C, creating a 3D network stabilized by hydrogen bonds and hydrophobic interactions, with gel strength dependent on molecular weight and sulfate content.
Provides vegan alternatives to gelatin with higher melting points (85°C vs 35°C) and thermo-reversible properties ideal for plated desserts.
