suitable for the measurement
of even trace levels of fructan (inulin or fructooligosaccharides,
FOS) in plant and food
products e.g. in grain and in infant formulations.
The “removal” of interfering sugars through
borohydride reduction also reduces the terminal
reducing fructose in partially hydrolysed
fructans. This leads to an underestimation of
up to 20% for highly depolymerised fructans.
However, if the pure FOS ingredient is available,
the level of underestimation can be determined
and allowed for.
