Mannitol is a six-carbon polyol extracted from brown algae cells and has two configurations, D and L. The L configuration is a synthetic product and does not exist in nature. The D configuration is widely distributed in the plant kingdom. In particular, the marine brown algae of the kelp family have a high content, mannitol is a storage substance in brown algae cells, and large brown algae such as kelp are the main raw materials for the extraction of mannitol.
There are two kinds of mannitol in industrial production: one is natural mannitol extracted from kelp as raw material, and the other is synthetic mannitol processed from sucrose and glucose.
2.Medicine
Because of its good compressibility, it has become an excellent excipient in the pharmaceutical industry.
3. Chemicals
Mannitol is esterified and etherified to form various resins and surfactants. Mannitol ester can be used as polyvinyl chloride plasticizer; Polyurethane rigid foamcan be used for thermal insulation, sound insulation and moisture-proof materials.
