1. The main form of sorbitol is liquid and solid: liquid sorbitol is mostly 50% or 70% colorless transparent aqueous solution; The appearance of solid sorbitol is white needle-like, flaky or granular crystalline powder, and some contain 0.5 or 1 molecule crystal water.
2. Sorbitol has a unique flavor, cool and refreshing taste, and its sweetness is about 60% of sucrose of the same concentration.
3. Sorbitol is highly soluble in water, slightly soluble in methanol, ethanol and acetic acid.
At 20ºC, the solubility of sorbitol is 220g/100mL water, and sucrose is only 195g/100mL water. Due to its large solubility in water, sorbitol is not easy to crystallize during industrial production. Under the same conditions, the viscosity of sorbitol solution is slightly lower than that of sucrose.
4. Sorbitol has great hygroscopicity, hygroscopicity is much greater than sucrose, slightly less than glycerin, and it is easy to absorb moisture when the relative humidity of the air is large.
5. The aqueous solution of sorbitol will cause the freezing point to drop, which can be applied to frozen food to avoid the appearance of ice residue, reduce the precipitation of crystal suspension or precipitation, and effectively improve the taste of the product.
6. Sorbitol molecules do not contain reducing groups, chemical properties are relatively stable, non-combustion, non-volatile, acid and alkali resistance, not easy to be oxidized by air. The thermal stability of sorbitol is good. 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 the osmotic pressure is close to glucose, which is 1.88 times that of sucrose. It can be used to control microorganisms in fruit and vegetable sauces.
