Abstract: The present invention includes a first method, in order to be able to determine correlation function-related reference values, and a second method and an arrangement in order to allowing to determine, during a dough-forming phase or sequence of a dough structure having time-related increasing rheological properties in a dough mixer driven by an electric motor, a point of time (t3) when the rheological properties of the dough structure exhibit a preset value, by means of allowing to detect instantaneous current values of the supply current (4a?) connected to the motor (4) over time in a first means (51) during said dough-forming phase. In this connection, for said second method and said arrangement, it is suggested: a. that a means (53) is adapted to allowing to evolve or calculate an envelope (53?) from the values (4a?) of the supply current detected in this way; b.
