The effects of different film coating agents (CMC-Na, Arabic gum and sodium alginate), the time point of film coating agent addition, the concentrations of CMC-Na and sodium alginate (added separately) and the ratio of CMC-Na to sodium alginate when added together at 1% in total on oil uptake were probed. In comparison with the control (without the addition of any film coating agent), CMC-Na, Arabic gum and sod
