Practical application
 Food Industry
 Sugar and sugar alcohol mannitol in water absorption in the smallest, and has a refreshing sweetness, for maltose, chewing gum, cakes and other foods of anti-sticking, as well as general anti-sticking pastry flour, can also be used in patients with diabetes, food , aerobics and other low-calorie food, low-sugar sweeteners, food intake each day to see if it may be more than 20g, then the label should indicate "excessive consumption may produce laxative effects."
 Chemical Industry
 Mannitol as the initiator and propylene oxide and KOH catalyst, 100 ~ 150 ℃ and pressure of mannitol made ​​of polyethylene - propylene oxide ether is widely used in the plastics industry, mannitol, poly - propylene oxide ether-based rigid polyurethane foam oil resistance, heat resistance and oxidation stability are good size, heat resistance is as high as 180 ℃. In the fine chemical industry, the stearic acid and mannitol in the presence of alkaline catalyst esterification reaction of stearic acid ester of mannitol wide range of uses: as a food emulsifier, dispersant can be used in cakes mannitol injection
 Point, candy, drinks, etc., but also for paint, textile, daily chemical and pharmaceutical industries emulsifier and dispersing agent. Polyoxypropylene mannitol two trioleate (trade name: Atlas G-2800) is also a good wetting agents and emulsifiers. In addition, mannitol is used for making rosin ester resins and synthetic glycerin, explosives, detonators (nitrification mannitol), in the plastics industry as PVC plasticizers, in cosmetics as a moisturizing agent. Used in chemical analysis of the determination of boron. Bacterial culture used as biological agent detection.
