Abstract: The present invention provides a method for citrus fruit processing comprising the steps of introducing liquid citrus fruit material to be processed via an inlet to a centrifugal separator being mechanically hermetically sealed at the inlet and at the liquid outlets; separating the citrus fruit material in the separator to obtain at least a liquid heavy phase and a liquid light phase, wherein the density of the liquid heavy phase is higher than the density of the liquid light phase; discharging the liquid heavy phase via a liquid heavy phase outlet and the liquid light phase via a liquid light phase outlet of the separator; measuring at least one parameter of the discharged liquid heavy phase and/or liquid light phase, wherein the parameter is related to a concentration of the heavy phase in the liquid light phase, or vice versa; and adjusting the counter pressure of the liquid heavy phase outlet with respect to the liquid light phase outlet, or vice versa, based on the measurement in step d) so as to control
