Stabilizers & Fibers
Gelatin Powder in gelato
Gelatin powder is a nearly pure protein (~85-88%) derived from partially hydrolyzed collagen. In gelato it acts as a gelling stabilizer, binding free water and building body without adding sugars, fat, or freezing-point depression.

Open the balancerHow to use it in gelato
Gelatin is used purely for texture: it binds free water, raises viscosity of the mix, and forms a thermoreversible gel that improves body, slows melt, and limits ice-crystal growth. Because it contains no sugars, salt, or alcohol it has zero POD and zero PAC, so it does not shift sweetness or the freezing curve, letting you firm up a mix without rebalancing sugars. Hydrate (bloom) it in cold water, then dissolve into the warm mix (dissolves ~50-60 C); over-dosing yields a gummy, chewy set rather than a clean scoop.
Origin & background
Gelatin has been produced industrially since the 19th century by hydrolyzing collagen from pork skin, hide, and bones; today porcine and bovine skins are the dominant sources. Its gel strength is graded by the Bloom value (typically 50-300 for food gelatin), a scale introduced by Oscar T. Bloom, who patented the Bloom gelometer in 1925.
