Glucomannan from Konjac Flour

Konjac flour is a hydrocolloidal polysaccharide from the tubers of Amorphophallus species of plants. It is a glucomannan polysaccharide consisting of β-1,4 linked glucose and mannose with a molar ratio of 1.6(mannose):1.0(glucose). It is commonly used as a diet aid, gelling agent, thickener, and emulsifier.

Services Provided:

Percent glucose and mannose (by HPLC)

Immunoglobulin Assay
IgG, IgM, IgA from various species by ELISA

Inulin and oligofructose occur in foods such as chicory, garlic, onion, artichoke, asparagus, and leeks.  The associated fructans are fermented by desirable bacteria such as Bifidobacteria.  It is thought that a number of health benefits are associated with increased levels of Bifidobacteria including reductions in Clostridia and coliform bacteria and antimutagenic and anticarcinogenic properties (Sparkes et al., 1998; Reddy, 1999).

Services Provided:
