Xylitol and Erythritol are part of a range of sugar alcohols, or polyols but none of them are neither sugars nor alcohols. They are carbohydrates with a chemical structure that partially resembles sugar and partially resembles alcohol, but they don’t contain ethanol as alcoholic drinks do.
Huletts EquiSweet Xylitol is a low GI sweetener derived from maize corncob fibres and contains no added additives. It is slowly and partially absorbed and metabolised, resulting in very negligible changes in blood glucose levels.
Huletts EquiSweet Erythritol is a low glycaemic response with a near zero kilojoule value. Among the sugar alcohols, it has a higher digestive tolerance because about 90% of the ingested Erythritol is readily absorbed and excreted in urine. Erythritol is a low kilojoule sweetener as opposed to Xylitol whose kilojoule levels are not low enough to be legally classified as a low kilojoule sweetener.
