Abstract: In a method for treating food in a food handling device with a parameter configuration a measured value distribution of a surface property of the food is determined after expiration of the period of time by means of a sensor. A pattern of change is calculated from a comparison of the p-th measured value distribution with a measured value distribution determined previously. An assessment value Bq which represents a difference between a deviation of a target distribution from the measured value distribution and a deviation of the target distribution from a prediction pattern is calculated for all patterns of change stored hitherto. The prediction pattern is formed by superimposing the measured value distribution with the respective pattern of change, and the parameter configuration is set for which the assessment value Bq meets at least one predetermined criterion.

Abstract: A household microwave appliance operates with multiple parameter configurations to treat food to be cooked in a locally differing manner. The microwave appliance determines in an initial scan with a thermal imaging sensor directed into the cooking chamber a temperature distributions on a surface of the food to be cooked. Change patterns are obtained from differences between different temperature distributions. An evaluation value is calculated for a best heating pattern that brings the current temperature distribution closest to a target temperature distribution determined based on a normalized target state and a current temperature distribution, whereafter microwave power is applied to the food to be cooked with the parameter configuration associated with the best heating pattern.
