Gelling capacity

Gelling capacity is one of the functional properties of a substance, concerned with its ability to form a gel, usually expressed as the gel strength achieved per unit concentration under defined conditions. Ingredient suppliers measure it to standardise batches of pectin, gelatin or carrageenan, since natural variation in raw materials would otherwise cause inconsistent texture in jams, desserts and confectionery from batch to batch. Buyers specify minimum gelling capacity in purchase contracts, and quality laboratories verify it with texture analysers or bloom tests. Reliable gelling capacity data let formulators dose hydrocolloids precisely and hold finished-product texture steady.
