The invention relates to a method for reducing the pulp content of fruit juices, particularly citrus juices, containing pulp, wherein the fruit juice is continuously purified of a pulp phase in the centrifugal field of a separator (3), said pulp phase being drawn from the separator drum through a fluid discharge, characterized in that the density of the pulp phase drawn from the separator is measured using a density flow-through measuring device (14) and that according to said density measurement at least one controllable device (15, 17) is controlled. The density of the pulp phase can be influenced by the control of said device.
