A food management system is provided. The food management system includes a plurality of electrodes arranged to be spaced apart from each other with food therebetween, a frequency modulator configured to adjust a frequency of power supplied to the plurality of electrodes, memory, comprising one or more storage media, storing instructions, and at least one processor communicatively coupled to the plurality of electrodes, the frequency modulator, and the memory, wherein instructions, when executed by the at least one processor individually or collectively, cause the food management system to control the frequency modulator such that power at each of a plurality of frequencies is sequentially supplied to the plurality of electrodes, determine a resonance frequency based on an impedance of the food at each frequency, determine a state of the food based on the resonance frequency of the food, and perform an operation corresponding to the determined state of the food.
