1. A food monitoring apparatus comprising:
at least one light source configured to selectively radiate light of a first wavelength band and light of a second wavelength band that is different from the first wavelength band to food;
at least one image sensor configured to obtain a visible image of the food and a hyperspectral image of the food based on light scattered, emitted, or reflected from the food; and
at least one processor configured to obtain first information of the food based on the visible image, and to obtain second information of the food based on the first information and the hyperspectral image,
wherein the at least one processor is further configured to obtain at least one parameter representing a content of an indicator material included in the food from the hyperspectral image, the indicator material emitting fluorescence based on the light radiated by the at least one light source, and
wherein the at least one processor is further configured to correct, based on the first information of the food obtained based on the visible image, a value of the at least one parameter obtained from the hyperspectral image, and obtain the second information based on the corrected value of the at least one parameter.
