As an excipient for tablets, mannitol is non-hygroscopic, fast drying, good chemical stability, and has the characteristics of crispness, good granulation, etc. It is used in most of the tablets such as anticancer drugs, antibacterial drugs, antihistamines and vitamins.
In addition, it is also used in chewable tablets such as sobriety medicine and mouth coolant. In terms of food, D-mannitol in sugar and sugar alcohols in the minimum water absorption, and has a refreshing sweetness, used for maltose, chewing gum, rice cakes and other food products, anti-stick, as well as used as a general pastry anti-stick powder.

D-Mannitol, colorless to white needle-like or rhomboid columnar crystals or crystalline powder. Odorless, with a cool sweet taste. Sweetness is about 57% to 72% of sucrose. Produces 8.37J of heat per g, about half of glucose. Contains a small amount of sorbitol.
Relative density 1.49, spin rate [α]D20-0.40°(10% aqueous solution). Hygroscopicity is very small. Stable in aqueous solution. Stable to dilute acid and alkali. Not oxidized by oxygen in air. Soluble in water (5.6g/100ml, 20°C) and glycerol (5.5g/100m1). Slightly soluble in ethanol (1.2g/100m1). Soluble in hot ethanol. Almost insoluble in most other commonly used organic solvents.
The pH of 20% aqueous solution is 5.5-6.5.
Product Methods of Bulk D-Mannitol Powder.
50% sucrose aqueous solution in nickel-catalyzed hydrogenation, about one-fourth of the conversion into mannitol, the rest into sorbitol, and then crystallized, separated, refined and obtained. Can also be iodized kelp soaked, neutralized with alkali, electrodialysis, concentration, crystallization, separation, and refined.
