Erythritol refers to a class of
sugar alcohols.
In nature, erythritol is present in algae and lichens, in fermented foods (wine, miso, aged cheeses), in some ripe fruits (melon, pears and grapes), berries (strawberries, watermelon), nuts (pistachios), and also in small amounts in mushrooms.
On an industrial scale this sweetener has been produced since 1990 by fermenting the carbohydrates in wheat or corn flour.
After fermentation, the raw material is purified and crystallized, then dried and given a typical appearance resembling regular table sugar.
As a food additive, erythritol was registered in the European Union in 2008 under the code E968.
