Mannitol is more than just a sweetener; it's a complex carbohydrate with fascinating origins and versatile industrial applications. Understanding its production pathways and chemical properties provides insight into why it's such a valuable ingredient across multiple sectors. NINGBO INNO PHARMCHEM CO.,LTD. ensures the supply of high-purity Mannitol, processed through advanced methods.

Naturally, Mannitol is a sugar alcohol (polyol) found in various plants, fungi, and algae. It's a product of plant metabolism and can be isolated from sources like seaweed and certain trees. Industrially, Mannitol is primarily produced through two main methods: chemical hydrogenation of fructose or enzymatic/fermentative processes. Chemical hydrogenation involves converting fructose using hydrogen gas and a catalyst, typically Raney nickel, under specific temperature and pressure conditions. Biotechnological routes utilize microorganisms like yeasts or bacteria to convert sugars into Mannitol through fermentation, offering a more sustainable production pathway.

Chemically, Mannitol is a hexitol with the molecular formula C6H14O6. It is a stereoisomer of sorbitol, differing only in the spatial arrangement of the hydroxyl group on the second carbon atom. This structural difference imparts unique properties, such as its lower hygroscopicity compared to sorbitol, making it more stable in humid environments. Mannitol has a melting point typically around 167-170°C and a high negative heat of solution, giving it a characteristic cooling taste. Its solubility in water is moderate, and it is practically insoluble in ethanol.

These properties lend Mannitol to a wide range of applications. In food, it's used as a sweetener, bulking agent, and anti-caking agent. In pharmaceuticals, it serves as an excipient in tablets and as an osmotic diuretic. The fine chemical industry also utilizes it, for instance, in the production of Mannitol stearate, an emulsifier. For businesses looking to buy Mannitol that adheres to strict quality standards, NINGBO INNO PHARMCHEM CO.,LTD. is a reliable source, offering Mannitol produced with precision and care.
