Granular Erythritol offers the sweetness of sugar with a fraction of the calories. This white powder is made from glucose that is fermented with yeast, a process similar to what occurs naturally in some fruits and fermented foods, resulting in a very sweet taste. With just 6 percent of the calories of sugar, it is commonly used as a low-calorie sweetener. Ideal for those managing their sugar intake, Erythritol is known for not causing the same blood sugar spikes as regular sugar. It is also used in diet beverages as part of a sweetening blend.
