Nutritional food additives. Sorbitol is white hygroscopic powder or crystalline powder, flake or granule, and it is odorless. Soluble in water (1g in about 0.45mL of water), slightly soluble in ethanol and acetic acid. It has a cool sweetness, the sweetness is about half of that of sucrose, and the calorific value is similar to that of sucrose. It is a nutritional sweetener, wetting agent, chelating agent and stabilizer, and is widely used in food production. According to different crystallization conditions, the melting point varies in the range of 88 ~102 degrees Celsius, and the relative density is about 1.49. Soluble in water (1g in about 0.45mL of water), slightly soluble in ethanol and acetic acid. It has a cool sweetness, the sweetness is about half of that of sucrose, and the calorific value is similar to that of sucrose. Sorbitol solution is a clear colorless syrup-like liquid, sweet, neutral to litmus, and miscible with water, glycerol and propylene glycol.
