Definition
Partially hydrolyzed collagen obtained by heating collagen in water.

Detailed Explanation

Partially hydrolyzed collagen obtained by heating collagen in water. Unlike collagen peptides, gelatin retains enough structure to gel at cool temperatures — the basis for gelatin desserts, capsules, and photographic film. Gelatin dissolves in warm water (~40°C) and forms a thermoreversible gel on cooling. Collagen peptides are gelatin that has been further hydrolyzed into smaller fragments (~2–3 kDa) that no longer gel but dissolve in any temperature liquid and are more bioavailable.
