Erythritol, C4H10O4, is a novel bulk sweetener with a caloric value close to zero. Chemically, it is a four-carbon sugar alcohol (polyol). Erythritol, a white crystalline powder, is made through fermentation.
Based on this production process and its raw materials (carbohydrate substrates) erythritol is the first and only polyol that can claim to be natural. It occurs naturally in a wide variety of foods, including many fruits and mushrooms, as well as in fermented foods such as cheese, wine, beer, and soy sauce. 
Erythritol’s flavor profile is very similar to sugar, with approximately 70% of the sweetening power of sugar. Erythritol is non-cariogenic and has the highest digestive tolerance of the polyols.
