摘要：
Preparing food products which are cooked in a liquid (6) present in a cooking vessel (5) by an induction heating device (9) having a resonant circuit (4) with an induction heating coil (1), comprises: continuously determining a parameter value of the resonant circuit, preferably a period of time of a self-resonant oscillation of the resonant circuit； subjecting the resonant circuit with a high frequency square wave voltage； detecting a change of the parameter value within the period； evaluating the determined change of the parameter value； and terminating the heating phase. Preparing food products which are cooked in a liquid (6) present in a cooking vessel (5) by an induction heating device (9) having a resonant circuit (4) with an induction heating coil (1), comprises: continuously determining a parameter value of the resonant circuit, preferably a period of time of a self-resonant oscillation of the resonant circuit, which depends on a temperature of the cooking vessel, preferably cooking vessel base； subjecting the resonant circuit with a high frequency square wave voltage for supplying heating power to the cooking vessel, preferably to cooking vessel base, having a heating setpoint value, during the heating phase, where the heating setpoint value is changed periodically, and the heating setpoint value is set for a first duration to a first value within a period, and is set during the remaining duration of a second, smaller value； detecting a change of the parameter value within the period； evaluating the determined change of the parameter value to determine the boiling point of the liquid； and terminating the heating phase when the boiling point has been identified. An independent claim is also included for an induction heating device comprising a resonant circuit with induction heating coil and a control device.
