Description
Glucomannan is a linear polysaccharide comprising 1,4-β-linked D-glucosyl and D-mannosyl residues, where the glucose:mannose (Glc:Man) ratio varies considerably. Konjac (Amorphophallus konjac) glucomannan has a Glc:Man ratio of approx. 2:3, Aloe vera glucomannan a ratio of 1:2, and salep (Orchis mureo) glucomannan has a ratio of approximately 1:4. All of the polysaccharides are acetylated, which imparts water solubility. Glucomannans are major cell-wall reserve carbohydrates in tubers of several plant genera. At certain stages in the development of the plants, the glucomannan is degraded and serves as an energy source. The only industrially exploited glucomannan is konjac. Like carob galactomannan, this polysaccharide interacts with agar, carrageenan and xanthan to form solutions of increased viscosity or gels. This interaction is exploited in the pet-food industry in canned dog food. Recently, glucomannan has also been used in jelly sweets. In this application, the glucomannan has been found to be dangerous, leading to choking deaths of some consumers. This has led to a ban of these types of sweets in Europe and America, and a need for an accurate analytical procedure for glucomannan analysis.

Biological Functions
Weight Management:Glucomannan is a soluble fiber with a high molecular weight and viscosity compared to other fibers, providing enhanced support for weight management. Significant mean weight loss was observed in one 8-week double blind trial, an effect that may be due to the effect of konjac glucomannan on satiety. A later study demonstrated that addition of a resistance and endurance exercise training program to a glucomannan-rich diet provides enhanced support for healthy body composition, lipid metabolism and triglycerides. Cardiovascular Health: In several controlled trials, konjac glucomannan supported healthy lipid metabolism and triglyceride levels, possibly by promoting healthy bile acid secretion. Additionally, it supports healthy glucose utilization and vascular function to support overall cardiovascular health. GI Health: As a dietary fiber, konjac glucomannan supports GI regularity. Research indicates that it also promotes healthy microflora balance, enhancing the growth of lactobacillus and bifidobacteria for a healthy gastrointestinal tract.
