Sugars & Sweeteners
Xylitol in gelato
Xylitol is a five-carbon sugar alcohol (polyol) with the same sweetness as table sugar but roughly 40% fewer calories. In gelato it works as a bulk sweetener that both sweetens and lowers the freezing point far more than sucrose, softening the finished product.

Per 100 g of product, verified against independent food-science sources (listed below).
| Parameter | Value |
|---|---|
| Total Solids | 100% |

Typical use: Roughly 5-16% of the total mix, depending on whether it partially or fully replaces sucrose; kept low enough to stay under the polyol laxative threshold per portion.

Xylitol is prized in sugar-free and diabetic-friendly gelato because it delivers sucrose-level sweetness (POD 100) while depressing the freezing point about 2.2 times as much as sucrose (PAC ~220). That high PAC means a mix built on xylitol scoops much softer and can freeze too soft if xylitol simply replaces sucrose gram-for-gram, so it is usually paired with a low-PAC bulking solid (such as a polyol-free bulking agent, maltodextrin, or inulin) or blended with sucrose to rebuild body. Because it does not brown (Maillard) and resists crystallization better than sorbitol, it gives a clean, cooling mouthfeel. Its main limit is a laxative threshold, which caps the practical dose per serving.
Origin & background
Xylitol was first isolated around 1891 by German chemist Emil Fischer and his collaborators from beechwood. It rose to prominence in Finland during the sugar shortages of the Second World War, and Finnish dental research in the 1970s (the Turku sugar studies) established its non-cariogenic, tooth-friendly reputation that drives much of its commercial use today.
