If you’ve ever visited a brewery, you’ve gotten a peek into how fermentation works. Erythritol is made by fermenting glucose with Moniliella pollinis, a natural microorganism. It also naturally occurs in many fruits and vegetables like melons, grapes and asparagus. Erythritol is classified by the FDA as a zero-calorie, 4-carbon sugar alcohol that does not affect blood glucose.
Oligosaccharides are sweet, non-digestible carbohydrates sourced from select fruits and starchy root vegetables. Oligosaccharides are prebiotic fibers, so they’re not only tasty, but they can help stimulate beneficial bacteria in your gut.
Erythritol vs. Xylitol
Sugar alcohols (also called polyols) are common ingredients in sugar substitutes; the erythritol in Swerve Sweetener is one such sugar alcohol. Another common sugar alcohol is xylitol, which is quite different from erythritol and is not an ingredient in Swerve Sweetener. Here are a few ways the two differ.
Erythritol: 0 calories per gram
Xylitol: 2.4 calories per gram
