In typical DC chokes the AC ripple flux is normally small in comparison to the DC component. These days most DC supplies come from switched mode converters which operate at 50-250kHz, which means that any ripple on the DC is at the same frequency. This allows for much smaller filter component values than used for 50/60Hz mains supplies.
