Chemische Eigenschaften
The solubility of D-sorbitol (D-glucitol, is D-glucohexan-1.2.3.4.5.6-hexaol) in water is up to approximately 2,350 g/L at room temperature. Sorbitol is stable under the common processing conditions of foods. In addition to the dry sorbitol, syrups are available.
Sorbitol is, depending on the concentration, approximately 60 % as sweet as sucrose and noncariogenic.
In the European Union, sorbitol is approved as E 420 for a large number of food applications, in the United States as GRAS, and is also approved in many other countries.
Sorbitol is generally produced by chemical hydrogenation of glucose or, together with mannitol, by chemical hydrogenation of fructose.
Verwenden
Dulcitol is important in studies related to cataract formation, hepatosplenμly and mental retardation. It is used as a substrate to identify, differentiate and characterize galactitol dehydrogenase(s). It is also used as a reference compound in analytical procedures developed to analyze sugar alcohols in plants and food.
Verwenden
sorbitol absorbs moisture from the air to prevent skin dryness, and leaves the skin feeling smooth and velvety. However, if the skin’s moisture content is greater than that of the atmosphere, it will draw moisture out of the skin, thereby increasing the feeling of dryness. Sorbitol is used by formulators as a replacement for glycerin in emulsions, ointments, and various cosmetic creams. It is obtained from the leaves and in some cases the berries of mountain ash. Sorbitol also occurs in other berries, cherries, plums, pears, apples, seaweed, and algae.
Verwenden
Dulcitol is the reduction product of Galactose. An increase in the level of Dulcitol is often a result of metabolism defect caused by a defect in galactose-1-phosphate uridylyltransferase (an autosomal recessive disorder). Dulcitol buildup can also lead t
