ABSTRACT:
A method for controlling a cooking process in a cooking appliance having a sensor for measuring a gas concentration in the cooking chamber and an electric or electronic control system in communication with the sensor and including an evaluation circuit and a memory, includes ascertaining, as a function of a food to be cooked, a cooking end value stored in the memory. An output signal of the sensor is processed using the evaluation circuit so as to generate a cooking quotient. The cooking quotient at a point in time corresponds to a ratio of the first derivative of the output signal with respect to time to a first extreme value of the first derivative of the output signal with respect to time. A value of the cooking quotient is compared to the cooking end value using the evaluation circuit, and an appliance function is triggered.
