1. A method for performing a non-intrusive determination of an indication of wholesomeness of a particular unopened item of packaged aliment, the method comprising:

  • illuminating the particular unopened item of packaged aliment with electromagnetic energy at a plurality of different wavelengths through a transparent portion of packaging of the particular unopened item of packaged aliment to cause the electromagnetic energy to interact with the packaged aliment;

    obtaining spectral information regarding the interaction of the plurality of different wavelengths with the particular unopened item of packaged aliment as subsequent spectral information based on the illuminating;

    examining a portion of the packaging of the particular unopened item of packaged aliment to identify an identity code that is uniquely associated with the particular unopened item of packaged aliment, the identity code further associated with a particular instance of original spectral information regarding a previous interaction of electromagnetic energy at the plurality of different wavelengths with the particular unopened item of packaged aliment;

    obtaining the particular instance of original spectral information based on processing the identity code; and

    determining an indication of a degree of wholesomeness of the particular unopened item of packaged aliment based on a determination of a spectral deviation between the particular instance of original spectral information and the subsequent spectral information, the determination of the spectral deviation based on application of an empirical relationship to the spectral deviation, the empirical relationship includes an association of values of spectral deviation with degrees of wholesomeness of unopened items of packaged aliment.
