Sorbitol alias sorbitol, English names Sorbitol, D-Glucitol, Sorbol, D-Sorbitol. The molecular formula is C6H14O6, which is the main photosynthesis product of Rosaceae plants. It is white hygroscopic powder or crystalline powder, flakes or granules, odorless. Depending on the crystallization conditions, the melting point varies from 88 to 102°C, and the relative density is about 1.49. It is easily soluble in water (1g can be dissolved in about 0.45mL water), slightly soluble in ethanol and acetic acid. It has a refreshing sweetness, the sweetness is about half of that of sucrose, and its calorific value is similar to that of sucrose. It will not cause dental caries when used as a sweetener. In the food industry, it is mostly 69~71% sorbitol liquid. Toxicity test shows that overdose internally can cause diarrhea and digestive disorders
1. It can be used as a raw material for the production of vitamin C. Sorbitol can be produced by fermentation and chemical synthesis. It can also be used as a raw material for industrial surfactants to produce Span and Tween surfactants. Sorbitol has moisturizing properties and can be used in the production of toothpaste, cigarettes and cosmetics instead of glycerin. Using sorbitol and propylene oxide as raw materials, rigid polyurethane foams with certain flame retardant properties can be produced. In the food industry, it can be used as a sweetener, moisturizer, chelating agent and tissue modifier. In the pharmaceutical industry, the sorbitol ester produced by nitration of sorbitol is a drug for the treatment of coronary heart disease. Food additives, cosmetic raw materials, organic synthetic raw materials, humectants, solvents, etc. 2. Nutritive sweeteners, wetting agents, chelating agents and stabilizers. It is a special sweetener with moisturizing function. It is not converted into glucose in the human body and is not controlled by insulin. It is suitable for diabetic patients. It can be used in cakes, the maximum use amount is 5.0g/kg; in surimi and its products, the maximum use amount is 0.5g/kg. It can also be used as a defoamer for sugar making process, brewing process and soy product process, and it can be used in appropriate amount according to production needs. It can also be used to moisturize raisins, thicken and preserve aroma of alcoholic beverages and soft drinks, as well as candy and chewing gum. 3. Synthetic resin and plastic, separate and analyze low boiling point oxygen-containing compounds, etc. It is also used as a gas chromatography stationary liquid, thickener, hardener, insecticide, etc. 4. Used as a gas chromatography stationary liquid for the separation and analysis of low-boiling oxygen compounds, amine compounds, nitrogen or oxygen heterocyclic compounds. Also used in organic synthesis. 5. Used as a moisture regulator for toothpaste, cosmetics, and tobacco. It is a substitute for glycerin, its moisture retention is milder than that of glycerin, and its taste is better. It can be used in combination with other moisturizers to achieve a synergistic effect. It is also used in the pharmaceutical industry as a raw material for the manufacture of vitamin C. 6. Diuretic dehydrating agent. It is used for the treatment of cerebral edema and increased intracranial pressure, the treatment of increased intraocular pressure for glaucoma, and also used for edema and oliguria with normal heart and kidney function. 7. Aquatic water retention agent. [4] The ratio of sucrose 2.1% + sorbitol 3.15% + complex phosphate 1.00% can effectively reduce the water activity of dried fish fillets and increase the activity of Ca-ATPase.
