Description
Pectin gelification is the formation of a firm, jelly-like network from pectin polysaccharides under acidic, sugary, or calcium-rich conditions.
Technical
The process relies on protonation of carboxyl groups in high‑methoxyl pectin, allowing hydrogen bonding and network formation, while low‑methoxyl pectin cross‑links via calcium ions. Sugar reduces water activity, creating an osmotic environment that stabilizes the gel. Temperature control is critical to avoid depolymerization of the pectin chains.
