Method for determining a moment in a preparation process of food at which the food has reached a ready state

A method for determining a moment in a preparation process of food at which the food. has reached a ready state, the method comprising the following steps: - determining a initial water content, ofthe food; - determining a final water content of the food, which is associated with the ready state of the food; - determining an actual quantity of the food; - determining a. required quantity of released water, i.e. a quantity of water to be released during the preparation process in order for the food to reach the ready state, 'on the basis of the determinedd actual quantity of the food and a difference between the initial water content of the food and the final water content of the food; and - performing measurements during the preparation process in order to determine a moment on which an actual quantity of released water corresponds to the required quantity A preparation device (1) for subjecting food to a preparation process, comprising: - weighing means (20) for performing weighing processes and - controlling means for registering and processing results of the weighing processes as performed by the weighing means (20), wherein the controlling means are programmed such as to perform the above method.
