Disclosed is a sample ingredient analysis apparatus including a first spectrum collection unit configured to radiate first light to a sample in order to generate a first spectrum and to concentrate the first spectrum, a second spectrum collection unit configured to radiate second light to the sample in order to generate a second spectrum and to concentrate the second spectrum, a data analyzer configured to receive the first and second spectra from the first and second spectrum collection units, to generate first and second spectral data based on the first and second spectra, and to calculate the first and second spectral data in order to obtain spectral data, and a data terminal configured to receive the first and second spectra data and the spectral data from the data analyzer and to display the first and second spectra and the spectral data to the outside.
