A method for influencing the pulp content of a fruit or citrus juice. The method steps include: continuously purifying the juice of a pulp phase in a centrifugal field of a separator, the pulp being discharged from a drum of the separator through a pulp discharge line measuring a density of the discharged pulp phase by a density flow-through measuring device and, controlling a controllable device in accordance with a density measurement by the density flow-through measuring device thereby influencing the density of the pulp phase.
