After incubation of excess amounts of curcumin with 10.0 m/m % βCDP and βCPCD solutions for 24 h, the supernatant was removed and the solid sedimented phase was further washed and incubated with purified water in two washing steps for 24 h in each step. The solubilized curcumin in the supernatant after each wash was determined and compared to the curcumin dissolved without cyclodextrin polymers (data are presented as means ± SD, n = 3. Labels of the significant differences are the following: **** p < 0.0001, ** p < 0.01, * p < 0.05).
