The manufacturer of Mannitol powder tells you that there are two types of industrially produced mannitol: one is natural mannitol extracted from kelp, and the other is synthetic mannitol processed from sucrose and glucose.

Mannitol is an isomer of sorbitol, and its molecular formula and molecular weight are the same as those of sorbitol. Sorbitol has strong hygroscopicity, but mannitol has no hygroscopicity at all. The sweetness of mannitol is equivalent to 70% of that of sucrose. The human body can absorb, partially metabolize, and partially excrete through urine. Mannitol powder manufacturers tell you that mannitol is mainly used in medicine and food, and can be used as food additives, sugar-free sweet foods, and feed additives.
Mannitol, also known as wood alcohol, is a hexaol that can be used as a diuretic or sweetener. Mannitol powder manufacturers tell you that mannitol is a polyol (polyol) produced by the hydrogenation of fructose and used as a sweetener, humectant and bulking agent. Low hygroscopicity and poor oil resistance. It has 1.6 kcal/g. Its water solubility is about 22%, its sweetness is about 72% of that of sugar, and it has a refreshing sweet taste. It works with the starch in the gum to remove dust. It is used in sugar-free candy, chewing gum, cereal and mints.
