What You Need to Know
During heating, pectin transitions from a soluble polysaccharide to a cross‑linked gel network as hydrogen bonds are disrupted and water acts as a plasticizer. Concurrently, hemicellulose partially solubilizes and cellulose begins to depolymerize, increasing water retention and softening the fiber matrix. Calcium ions (1–2 % w/w CaCl₂) further cross‑link pectin, enhancing gel firmness and mechanical stability.
