Product Description
Glucomannan is a slightly branched polysaccharide composed of mannose and glucose in a molar ratio of approximately 1.5–2.0 to 1.0, linked by β-1,4-glycosidic bonds. It is derived from the tuber of the Amorphophallus plant and purified to obtain a high-grade material. Depending on the grade, its average molecular weight ranges from below 200,000 to over 2,000,000.

Manufacturing
Acetyl groups along the glucomannan backbone contribute to its solubility and are located, on average, at every 9 to 19 sugar units.

Shimizu 's unique high-purifying process is carried out in a large-scale purification plants. The Amorphophallus plant tubers are first pulverized, and then the collected glucomannan particles are polished in order to dislodge and wash out noxious materials adhering to them. This process yields a refined, high performance glucomannan with a high degree of purity that improves product solubility, stability and overall functionality.
The particles are tasteless, odorless and white in color.
