149-32-6 Erythritol In China CAS NO.149-32-6

meso-Erythritol is used to support the carbon source growth requirement of Gluconobacter bacteria. It is also used in the chemical analysis of the reactivity of various radicals and radical anions, in encapsulated phase change materials (PCMs) to study its potential use in microelectronics cooling applications, as a reference compound in purification and analytical procedures developed to test fermentation broths

meso-Erythritol is an allelic variation of the Tas1r3 gene which affects behavioral taste responses to sugar alcohol, suggesting that it is a T1R3 receptor ligand.

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.

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.
