Xucker is pure Erythritol, a great calorie free sugar alternative, which however possesses 70 % of the sweetening power of sugar. Xucker light is the perfect sweetener for all deserts and hot beverages. It is not really suitable for baking. Xucker light is tooth-friendly, but does not have the same tooth cleaning properties like xylitol. Xucker light is produced naturally by fermentation of glucose in France. Awesome, isn´t it?
