Erythritol is a chemical compound, a sugar alcohol (or polyol), used as a food additive and sugar substitute. It is naturally occurring and is made from corn using enzymes and fermentation. Its formula is C4H10O4, or HO(CH2)(CHOH)2(CH2)OH; specifically, one particular stereoisomer with that formula.

Erythritol is 60–70% as sweet as sucrose (table sugar), yet it is almost noncaloric[1] and does not affect blood sugar[2] or cause tooth decay.[3]

Erythritol was discovered in 1848 by Scottish chemist John Stenhouse.[4] Erythritol was first isolated in 1852. In 1950 it was found in blackstrap molasses that was fermented by yeast, and it became commercialized as a sugar alcohol in the 1990s in Japan.[5]

Erythritol occurs naturally in some fruit and fermented foods.[6] At the industrial level, it is produced from glucose by fermentation with a yeastMoniliella pollinis.

Since 1990, erythritol has had a history of safe use as a sweetener and flavor-enhancer in food and beverage products, and is approved for use by government regulatory agencies of more than 60 countries.[8] Beverage categories for its use are coffee and tea, liquid dietary supplements, juice blends, soft drinks, and flavored water product variations, with foods including confections, biscuits and cookies, tabletop sweeteners, and sugar-free chewing gum.[8]

Erythritol is absorbed rapidly into the blood, with peak amounts occurring in under two hours; the majority of an oral dose (80 to 90%) is excreted unchanged in the urine within 24 hours.[8]

As a test of safety, scientists assessed doses for erythritol where symptoms of mild gastrointestinal upset occurred, such as nausea, excess flatus, abdominal bloating or pain, and stool frequency. At a content of 1.6% in beverages it is not considered to have a laxative effect.[8] The upper limit of tolerance was 0.78 and 0.71 grams per kg body weight in adults and children, respectively.[8] For safe use in children, a scientific panel for the European Food Safety Authority recommended the upper limit content per food or beverage serving was 0.6 grams per kg body weight.[8]

Dietary and metabolic aspects

Caloric value and labeling

Nutritional labeling of erythritol in food products varies from country to country. Some countries, such as Japan and the European Union (EU), label it as zero-calorie.[9]

Under U.S. Food and Drug Administration (FDA) labeling requirements, it has a caloric value of 0.2 kilocalories per gram (95% less than sugar and other carbohydrates). The FDA has not made its own determination regarding the generally recognized as safe (GRAS) status of erythritol, but has accepted the conclusion that erythritol is GRAS as submitted to it by several food manufacturers.[7]

Human digestion

In the body, most erythritol is absorbed into the bloodstream in the small intestine, and then for the most part excreted unchanged in the urine. About 10% enters the colon.[10]

In small doses, erythritol does not normally cause laxative effects and gas or bloating, as are often experienced after consumption of other sugar alcohols (such as maltitolsorbitolxylitol, and lactitol).[11] About 90% is absorbed before it enters the large intestine, and since erythritol is not digested by intestinal bacteria, the remaining 10% is excreted in the feces.[10]

Large doses can cause nauseastomach rumbling and watery feces.[12] In males, doses greater than 0.66 g/kg body weight and in females, doses greater than 0.8 g/kg body weight, will cause laxation,[13] and diarrhea in higher doses (over 50 grams (1.8 oz)).[12] Rarely, erythritol can cause allergic hives (urticaria).[14]

Blood sugar and insulin levels

Erythritol has no effect on blood sugar or blood insulin levels.[15][16] and therefore may become an effective substitute for sugar for diabetics.[5]

Oral bacteria

Erythritol is tooth-friendly; it cannot be metabolized by oral bacteria, so it does not contribute to tooth decay.[3][16] In addition, erythritol, similarly to xylitol, has antibacterial effects against streptococci bacteria, reduces dental plaque, and may be protective against tooth decay.[16]


Erythritol is produced industrially beginning with enzymatic hydrolysis of the starch from corn to generate glucose.[17] Glucose is then fermented with yeast or another fungus to produce erythritol. Other methods such as electrochemical synthesis are in development.[18] A genetically engineered mutant form of Yarrowia lipolytica, a yeast, has been optimized for erythritol production by fermentation, using glycerol as a carbon source and high osmotic pressure to increase yields up to 62%.[19]

Chemical properties

Heat of solution

Erythritol has a strong cooling effect (endothermic, or positive heat of solution)[20] when it dissolves in water, which is often compared with the cooling effect of mint flavors. The cooling effect is present only when erythritol is not already dissolved in water, a situation that might be experienced in an erythritol-sweetened frosting, chocolate bar, chewing gum, or hard candy. The cooling effect of erythritol is very similar to that of xylitol and among the strongest cooling effects of all sugar alcohols.[21] Erythritol has a pKa of 13.903 at 18 °C.[22]

Biological properties

According to a 2014 study,[23] erythritol functions as an insecticide toxic to the fruit fly Drosophila melanogaster, impairing motor ability and reducing longevity even when nutritive sugars were available.

Erythritol is preferentially used by the Brucella spp. The presence of erythritol in the placentas of goats, cattle, and pigs has been proposed as an explanation for the accumulation of Brucella bacteria found at these sites.[24]


In the 19th and early 20th centuries, several synonyms were in use for erythritol: erythrol, erythrite, erythoglucin, eryglucin, erythromannite and phycite.[25] Zerose is a tradename for erythritol.[26]
