Sucrose, raffinose and fructan concentrations
were assessed with high performance anion exchange chromatography
with pulsed amperometric detection (HPAEC-PAD).
Sugars were extracted with hot water (80 C, 1 h) and hydrolyzed
under mild acid conditions prior to HPAEC-PAD analysis to quantify
fructans (Verspreet et al., 2012).
