Inulin (Vegetable Fiber) in gelato
Inulin is a soluble prebiotic fiber extracted from chicory root, used in gelato as a bulking and body-building agent that adds total solids and creamy texture without contributing sugar, sweetness, fat, or freezing-point depression.

| Parameter | Value |
|---|---|
| Total Solids | 95% |
| Water | 5% |

Inulin is a fructose polymer (fructan), so unlike mono- and disaccharides its large molecules do not lower the freezing point: both PAC and POD are effectively 0. This lets you raise total solids and improve body, creaminess, and melt resistance without softening the gelato or adding sweetness. It acts as a fat and dairy-solids mimic, useful in vegan, low-fat, and low-sugar formulas where you need structure but must not add anti-freezing power. Because it is inert on the freezing curve, add it after balancing sugars and fats, then reduce other bulking solids to keep total solids in range. Note it is mildly exothermic on dissolving, giving a slight warming mouthfeel that can offset the cooling of high-PAC sorbets.
Origin & background
Inulin was first isolated in 1804 by German scientist Valentin Rose from the roots of Inula helenium (elecampane), the plant that gave the compound its name. Today it is produced industrially at scale from chicory root (Cichorium intybus), which naturally stores 15-20% inulin, by hot-water extraction and spray-drying.
