Chemical Properties

Erythritol (meso-erythritol, meso-1,2,3,4-Tetrahydroxybutan) has been known for a long time. Its potential use as a bulk sweetener was, however, recognized rather late.
Erythritol is a natural constituent of several foods and beverages in levels sometimes exceeding 1 g/kg. Its solubility in water is approximately 370 g/L at room temperature and increases with increasing temperature. Erythritol melts at 121 C and is stable up to more than 160 C and in a pH range from 2 to 10. Depending on the concentration used, erythritol is approximately 60 % as sweet as sucrose. It is noncariogenic and not metabolized in the human body which means that it is more or less calorie-free.
In the European Union, erythritol is approved as E 968 for a large number of food applications. It is GRAS in the United States and also approved in many other countries.

Uses

Erythritol is a sweetener (polyol) manufactured by fermentation of glucose, the glucose-rich substrate being obtained by the enzymatic hydrolysis of starch. it is 60–70% as sweet as sugar, has excellent heat and acid stability, a high digestive tolerance, and a caloric value of 0.2 kcal/g. it is the only polyol produced by fermentation. it can be used as a sugar replacement in confectioneries, beverages, and desserts.

Uses

non-cariogenic, low-calorie (0.4 kcal/g) sweetener

Definition

ChEBI: The meso-diastereomer of butane-1,2,3,4-tetrol.

Uses

Non-nutritive sweetener in beverages.

Biotechnological Production

The synthesis of erythritol is rather difficult. One of the possibilities is the catalytic reduction of tartaric acid with Raney nickel, which does, however, also produce threitol, a diastereomere of erythritol that requires separation of both. Threitol may be isomerized which increases the yields of erythritol. Another chemical synthesis starts from butane-2-diol-1.4 which is reacted with chlorine in aqueous alkali to yield erythritol-2-chlorohydrin and can be hydrolyzed with sodium carbonate solution. Synthesis from dialdehyde starch in the presence of a nickel catalyst at high temperatures is also possible.
Owing to the special physiological properties of erythritol, commercial interest increased with the discovery of an increasing number of microorganisms able to produce this substance. Today, the commercial production of erythritol is apparently only based on fermentation.
Erythrytitol fermentations mostly use osmophilic yeasts. Based on regulatory submissions for commercial production, T. megachiliensis, M. pollinis, and Y. lipolytica are used. It is also claimed that P. tsukubaensis and Aureobasidium sp. are used for commercial production.
Erythritol-producing microorganisms often produce other polyols such as ribitol. Nevertheless, some strains had a rather high yield of erythritol. A two-step fermentation of C. magnoliae on 400 g/L glucose resulted in a 41 % conversion rate and a productivity of 2.8 g/Lh. M. pollinis cultivated on glucose and several nitrogen sources yielded erythritol concentrations up to 175 g/L with a conversion rate of 43 %. Oxygen limitation resulted in ethanol formation, and nitrogen limitation in strong foaming. A mutant gave even better yields. Aerobically on glucose cultured P. tsukubaensis KN 75 produced 245 g/L of erythritol with an especially high yield of 61 %. The productivity was 2.86 g/Lh. Scale-up from 7-L laboratory fermenter to 50,000-L industrial scale resulted in productivities similar to the laboratory value.

Purification Methods

meso-Erythritol crystallises from distilled water or absolute EtOH and is dried at 60o in a vacuum oven. It sublimes at 110o in a high vacuum. It is optically inactive. [Jeans & Hudson J Org Chem 20 1565 1955, IR: Kuhn Anal Chem 22 276 1950, Beilstein 1 IV 2807.]
