~2 to 10, while inulin typically ranges from ~2 to 60, but there is variation
in this range depending on the inulin source. Because the DP of these compounds
varies, their solubility in 80% ethanol varies, and therefore their
inclusion in total dietary fiber (TDF) measurements is not complete.76 In
order to avoid overestimating the contribution of fructans by virtue of counting
them twice, the inclusion of an inulinase in the TDF procedure will
completely exclude fructans from being counted as a dietary fiber. Inulin
and oligofructose can then be determined in a separate analytical procedure
and their quantity as dietary fiber added to the TDF determined using
