Sorbitol is easily soluble in water (1g in about 0.45ml water), but not in ethanol and acetic acid. It has fresh sweetness, about half the sweetness of sucrose, and its calorific value is similar to sucrose. When used as a sweetener, it will not cause tooth decay. In the food industry, it is mainly liquid sorbitol, with a content of 69% - 71%. Toxicity tests show that oral overdose may lead to diarrhea and indigestion.

The molecular formula of sorbitol is C6H14O6, which is the main product of photosynthesis of rosaceae plants. It is white hygroscopic powder or crystalline powder, flakes or granules, odorless. Depending on crystallization conditions, the melting point varies between 88 and 102 °C and the relative density is approximately 1.49.

Glucose​ plays an important role in biology and is an energy source and metabolic intermediate of living cells, i.e. the main energy supplier for living organisms. Plants can produce glucose by photosynthesis. It is widely used in confectionery manufacturing and pharmaceutical fields. Let us read the following words and know more about the glucose.

Glucose is an organic compound with the formula C6H12O6. It is the most widespread and important monosaccharide in nature and a polyhydroxyaldehyde. Pure glucose is a colorless crystal with sweet taste, but not as sweet as sucrose, easily soluble in water, easily soluble in ethanol, insoluble in ether. Natural aqueous glucose solution is optically turned to the right, so belongs to the "dextrose".
