Sorbitol CAS 50-70-4

Short Description:

Sorbitol CAS 50-70-4

1. The main forms of sorbitol are liquid and solid: liquid sorbitol is mostly a colorless and transparent aqueous solution of 50% or 70%; Solid sorbitol appears as white needle shaped, flake shaped, or granular crystalline powder, some of which contain 0.5 or 1 molecule of crystalline water.
2. The flavor and sweetness of sorbitol are unique, with a cool and refreshing taste, and a sweetness level of about 60% of the same concentration of sucrose.
3. Solubility and viscosity: Sorbitol is highly soluble in water and slightly soluble in methanol, ethanol, and acetic acid. At 20 ℃, the solubility of sorbitol is 220g/100mL water, while sucrose is only 195g/100mL water. Due to its high solubility in water, sorbitol is not easily crystallized in industrial production. Under the same conditions, the viscosity of the pear alcohol aqueous solution is slightly lower than that of sucrose.
4. Moisture absorption and moisturizing properties: Sorbitol has a high moisture absorption capacity, far greater than sucrose and slightly smaller than glycerol. It is highly prone to moisture absorption and clumping when the relative humidity of the air is high; However, the hygroscopicity of sorbitol in the gamma crystal form is relatively low. Extend the shelf life of the product.
5. The aqueous solution of sorbitol can cause a decrease in freezing point. When applied to frozen foods, it can avoid the appearance of ice residue, reduce the precipitation of crystal suspensions or precipitates, and effectively improve the taste of the product.
6. Stable sorbitol molecules do not contain reducing groups, have relatively stable chemical properties, are non combustible, non-volatile, acid and alkali resistant, and are not easily oxidized by air. Sorbitol has good thermal stability; Under certain reaction conditions, sorbitol can undergo dehydration oxidation, esterification, etherification and other reactions, and can also chelate various metal ions in strong acid and alkali solutions.
7. The molecular weight of sorbitol is slightly larger than that of glucose, so its osmotic pressure is close to that of glucose, 1.88 times that of sucrose. A higher osmotic pressure means a correspondingly stronger resistance to microorganisms, which can be used to control microorganisms in fruit and vegetable sauces

1. The daily chemical industry uses sorbitol as an excipient, moisturizer, antifreeze agent in toothpaste, with an addition amount of up to 25-30%, which can maintain the lubrication of the paste, and provide good color and taste; As an anti drying agent (instead of glycerol) in cosmetics, it can enhance the extensibility and lubricity of emulsifiers, making it suitable for long-term storage; Sorbitol fatty acid esters and their ethylene oxide adducts have the advantage of low skin irritation and are widely used in the cosmetics industry.
2. Adding sorbitol to food in the food industry can prevent food from drying out and keep it fresh and soft. Used in bread and cake, it has a significant effect. Sorbitol has a lower sweetness than sucrose and is not utilized by certain bacteria. It is an important raw material for producing sugar free candies and various anti caries foods. Since the metabolism of this product does not cause blood sugar to rise, it can also be used as a sweetener and nutrient for food for diabetics. Sorbitol does not contain aldehyde groups, is not easily oxidized, and does not undergo Maillard reaction with amino acids when heated. It has certain physiological activity and can prevent the denaturation of carotenoids, edible fats, and proteins. Adding this product to concentrated milk can extend the shelf life and improve the color, aroma, and taste of the small intestine. It has a significant stabilizing and long-term preservation effect on fish sauce. It also has the same effect in jam and candied fruits.
3. Sorbitol in the pharmaceutical industry can be used as a raw material for the production of vitamin C; It can also be used as a raw material for syrup, injection infusion, pharmaceutical tablet pressing, drug dispersant, filler, cryoprotectant, anti crystallization agent, Chinese medicine stabilizer, wetting agent, capsule plasticizer, sweetener, ointment base, etc.
4. Chemical industry sorbitol rosin ester is a commonly used raw material for building coatings, which can be used as a plasticizer and lubricant in polyvinyl chloride resins and other polymers. Complex with iron, copper, and aluminum ions in alkaline solution, used for bleaching and washing in the textile industry.
