Method Reference:

AOAC 997.08

Method Description:

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 %.

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 the DP as well as the source of fructans.

Additional Information:

Fructans are 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.
