In a food analysis apparatus, the absorbance of a plurality of samples, of which nutrition information is already known, is classified in association with feature information including at least one item of information of a state, a temperature, a light intensity, a weight, or a color of the sample. In addition, a storage unit (30) stores a plurality of correlation models including a correlation model representing correlations between nutrition information of samples and the absorbance of the classified samples. A correlation model corresponding to feature information of object S is selected from the plurality of correlation models stored in the storage unit (30). The absorbance of object S is applied to the selected correlation model, and thereby nutrition information of the object S is analyzed by an analysis unit (31).
