The effects of sulfation, hydroxypropylation and succinylation on gelling, water uptake, swelling, and bile acid-binding capacities of psyllium were examined and compared on a same molar substitution degree. Sulfated, hydroxypropyl and succinyl psyllium were prepared with a substitution level of 1.02, 0.88 and 0.79, respectively, and their structures were characterized using FT-IR, SEM and ζ-potential determination. All of the three derivatization methods reduced the gelling and swelling capacities of psyllium, increased the water uptake and bile acid-binding capacities comparing to the original psyllium. Interestingly, it was observed for the first time that introduction of stronger negative charged group into the molecule might more effectively enhance the bile acid-binding capacity of psyllium. On the other hand, the steric effect of the substation groups seemed to be more critical in altering the gelling and swelling properties of psyllium.
