Forced roots of Belgian endive (Cichorium intybus var. foliosum) are by-products with promising valorization
potential. The roots of four cultivars grown in four locations and mixes derived thereof, were used to produce
dietary fibre concentrates (DFCs). Obtained DFCs were characterized by a low concentration of total sugars (TS),
phenolic compounds (PCs) and sesquiterpene lactones (SLs) and high content of the dietary fibre (DF) and
functional properties. On average, total dietary fibre content (TDF) was 82.93 g/100 g DW, where the insoluble
fraction was dominant (71.98–78.08 g/100 g DW). All DFCs showed high water (WHC) and oil holding capacity
(OHC) (9.95–15.48 g/g DW and 2.58–4.11 g/g DW, respectively) and swelling capacity (SWC)
(13.20–22.95 mL/g DW). Although differences in genotype and location induced variability in the studied parameters,
the DFCs showed similar DF profile and functionality, suggesting that forced roots represent a robust
feedstock for DFC production and developing market-relevant plant-based food products.
