    • The present invention relates to a method and apparatus for controlling a cooking process of food. The method comprises a step of emitting (101) a plurality of radio frequency signals into the food non invasively. The method also comprises a step of receiving (105) a plurality of reflection signals or transmission signals of the radio frequency signals from the food, wherein the reflection signals is a part of the radio frequency signals that reflect from the food, and the transmission signals is a part of the radio frequency signals that transmit through the food. The method also comprises a step of obtaining (110) 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 (120) a doneness level of the food based on the protein status, and a step of controlling (130) 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.
    • 本发明涉及一种用于控制食物烹饪过程的方法和装置。 该方法包括非侵入地将多个射频信号发射(101)到食物中的步骤。 该方法还包括从食物接收(105)多个反射信号或射频信号的传输信号的步骤,其中反射信号是从食物反射的射频信号的一部分,传输信号 是通过食物传播的射频信号的一部分。 该方法还包括以下步骤:基于多个射频信号和多个反射信号,获得(110)蛋白质状态(其中蛋白质状态是蛋白质变性的程度)在食物加热过程中的食物中 或传输信号。 该方法还包括基于蛋白质状态来确定(120)食物的多重性水平的步骤,以及基于确定的多汁性水平来控制(130)食物的烹饪过程的步骤。 蛋白质变性使用蛋白质变性提供了一个比较直接和准确的食物状态信息。
