The sorbitol (E420) is a Carbohydrate (Glucide) of the family of the Polyol S (like the Glycérol or the glycol for example) slowly metabolized by the organization.

Origin

The sorbitol holds its name of the sorb whose bays contain many sorbitol. But the fruit with higher content of sorbitol is in fact the Pruneau.

The sorbitol is the major product of the Photosynthèse, the principal glucid exported in the Phloème and a product for the temporary storage of carbon at the woody species of the family Rosaceae. At the species called to sorbitol, the synthesis of this one is in competition with that of the Saccharose because these two sugars have a common precursor, the Glucose-6-phosphate. The mechanisms which control and control the partition of C between these two ways are unknown. Nevertheless, the effects of the environment and the conditions of culture can play a big role to modify metabolic flows between the sorbitol, saccharose and the Amidon. The accumulation of sorbitol is regarded as an adaptive of the plants to the constraints saltworks, hydrous response and basic temperature. The synthesis of the sorbitol is confined with the bodies sources. Its degradation takes place only in the bodies well.

The sorbitol is also produced naturally by the human body but it is badly digested by the organization. An excess of sorbitol in blood can involve

• a Cataracte a deposit of sorbitol on the crystalline lens makes it more opaque. Attention, that has nothing to do with the Rétinopathie of the diabetes
• a Neuropathie (for the nerves)

Use

Analytical chemistry

The sorbitol is used as internal standard in the quantitative analysis of sugars by gas chromatography with Silylation.

Food

It is a sweetening used in the food of mode but also in many products processed by the agribusiness industry in which he plays the part of stabilizer. It provides 2.6 calories per gram, therefore less than the Sucre and thus increases only very little the Glycémie.

Medical

The sorbitol is also used as drug (without ordinance) in order to treat the Constipation, thanks to its effect Laxatif.

Cosmetic

The sorbitol is often used by the modern Cosmétique as a humidifying agent and thickener. It is found, often like dominating ingredient, in the majority of the Dentifrice S.

Counter-indications

In the event of Pregnancy or of Breast feeding, the catch of sorbitol is disadvised.
