The method also comprises a step of obtaining () a protein status, wherein the protein status is the extent of protein denaturation, in the food in the course of heating the food based on the plurality of radio frequency signals and the plurality of reflection signals or transmission signals. The method also comprises a step of determining () a doneness level of the food based on the protein status, and a step of controlling () the cooking process of the food based on the determined doneness level. Using the protein denaturation provides a more direct and precise information of the status of food based on established relation between the doneness level and the protein denaturation extent.
