This method allows the quantitative determination of fructans in foods. The fructans in a sample are digested enzymatically and quantified using liquid chromatography and measured as %.
Information Required by Submitter:
Please provide an estimate of the amount of fructans expected, the source of fructans, the sample matrix and expected degree of polymerization (DP).
Fructans are polydisperse mixtures of molecules that consist of fructose moieties linked to each other by beta(2-1) bonds. A glucose moiety may be linked to the end of the chain by an alpha(1-2) bond as in sucrose. The degree of polymerization may vary from 2 (or 3 in the case where there is a terminal glucose) to several hundred. The main components of fructans are inulin (primarily DP 2-60 with a typical average DP of 10 or greater) and oligofructose (DP 2-10) where DP is the Degree of Polymerization.
The official AOAC method for fructans quantification performed by Medallion Labs expresses the fructans result as an equivalence to chicory root fructans which have an average degree of polymerization (DP) of 10 units (i.e. 1 glucose unit plus 9 fructose units). If your sample does not originate from chicory root or has a DP different from 10, please specify source of fructans as well as the DP.
