As can be seen from Figure 2 d, with the extension of milling time, the CEC of PIDF showed a trend of first increasing and then decreasing, among which the CEC of PIDF-4 was the best ( p < 0.05), reaching 0.35 ± 0.0038 mmol/g.

The results showed that with the increase in ball milling time, the CAC of the three kinds of citrus fibers showed an increasing trend, which agrees with present studies.
