Discreption

The main forms of sorbitol are liquid and solid: liquid sorbitol is mostly 50% or 70% colorless transparent aqueous solution; solid sorbitol is white needle-like, flaky or granular crystalline powder, and some contain 0.5 or 1 molecule of water of crystallization.
Sorbitol is very soluble in water, slightly soluble in methanol, ethanol and acetic acid, etc. At 20°C, the solubility of sorbitol is 220g/100mL of water, and that of sucrose is only 195g/100mL of water. Due to its high solubility in water, sorbitol is not easy to crystallize during industrial production. Under the same conditions, the viscosity of sorbitol aqueous solution is slightly lower than that of sucrose.

Function

1. Daily chemical industry
Sorbitol is used as an excipient, humectant, and antifreeze in toothpaste, and the addition amount can reach 25-30%, which can keep the paste lubricated, with good color and taste; as an anti-drying agent (instead of glycerin) in cosmetics, it can enhance The extensibility and lubricity of the emulsifier are suitable for long-term storage; the sorbitan fatty acid ester and its ethylene oxide adduct have the advantages of little irritation to the skin and are widely used in the cosmetics industry.
2. Food industry
Adding sorbitol to food can prevent food from cracking and keep food fresh and soft. It has obvious effect when used in bread cakes. Sorbitol is less sweet than sucrose and cannot be used by some bacteria. It is an important raw material for the production of sugar-free candy and various anti-cavity foods. Because the metabolism of this product does not cause blood sugar to rise, it can also be used as a sweetener and nutrient for diabetics. Sorbitol does not contain aldehyde groups, is not easily oxidized, and does not produce Maillard reactions with amino acids when heated. It has a certain physiological activity and can prevent the denaturation of carotenoids, edible fat and protein. Adding this product to concentrated milk can prolong the shelf life and improve the color and aroma of the small intestine. It has obvious stability and long-term preservation effect on fish sauce . It also has the same effect in jam preserves.
3. Pharmaceutical industry
Sorbitol can be used as a raw material for vitamin C production; it can also be used as a raw material for syrup, injection infusion, and pharmaceutical tableting; as a drug dispersant, filler, cryoprotectant, anti-crystallization agent, traditional Chinese medicine stabilizer, wetting agent, and capsule plasticizer agents, sweeteners, ointment bases, etc.
4. Chemical industry
Sorbitol rosin resin is often used as a raw material for architectural coatings, and can be used as a plasticizer and lubricant in polyvinyl chloride resin and other polymers. It is complexed with iron, copper and aluminum ions in alkaline solution, and is used in bleaching and washing in the textile industry. Sorbitol and propylene oxide are used as starting materials to produce polyurethane rigid foams, which have certain flame retardant properties.
