Glucomannan is a water soluble polysaccharide chain of β-1,4–linked d -mannose and d -glucose monomers extracted from the root of the konjac plant. As human enzymes cannot break β-1,4 linkages, glucomannan passes through the colon relatively unchanged, where it is then fermented by gut microbiota.

2023年7月31日 · Glucomannan is a natural, water-soluble dietary fiber extracted from the roots of the elephant yam, also known as konjac. It may be an effective weight-loss supplement. However, only when taken...

Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener. It is a major source of mannan oligosaccharide (MOS) found in nature, the other being galactomannan, which is insoluble. [1]

2024年8月18日 · Glucomannan, the water-soluble dietary fiber supplement from the konjac plant, may help keep bowels regular, control body weight, and reduce blood cholesterol and blood sugar. The health benefits of glucomannan have been studied extensively and it is considered safe when taken as directed.

2024年9月1日 · The first approach involved dissolving glucomannan in water with Al 2 (SO 4) 3 as a flocculant, followed by purification using ethanol. The second approach included repeated ethanol milling (5–7 times) and glucomannan granule filtration for impurity separation without subsequent purification.

With its low energy density and bulking properties, glucomannan seems to promote weight loss by displacing the energy of other nutrients and producing satiety and satiation as it absorbs water and expands in the gastrointestinal tract.

2024年9月6日 · Glucomannan is one of the most viscous fibers. It can absorb up to 50 times its weight in water. It creates a thick gel when absorbed. Viscous fibers like glucomannan slow the digestion and absorption of nutrients, which creates a feeling of fullness (satiety). An increase in satiety can reduce food intake.

Glucomannan powder expands in water by 138-200% compared to ordinary starch, which can only expand 25% in water (Parry, 2010). Glucomannan solution in water has the properties of glue, but when adding acetic acid or acid in general, …

2017年9月1日 · Konjac glucomannan (KGM) is a water-soluble polysaccharide originated from the tuber of plant Amorphophallus konjac C. Koch with an average MW about 1000 kDa, which is composed of β - (1 → 4) linked d -mannose and d -glucose in a molar ratio of 1.6:1 or 1.4:1 (Huang et al., 2002, Nishinari and Takahashi, 2003).

Glucomannan is a water-soluble, fermentable dietary fiber composed of mannose and glucose combined by beta-1,4 glucosidic linkages in a molar ratio of 1.6:1. 1 Compared with other dietary fibers, it has the highest viscosity and molecular weight, ranging from 200,000 to 2,000,000 Da, which varies with origin, method of processing, and storage ...
