The paper reports an application of Generalised Canonical Correlation Analysis to fluorescence spectral data. Emission fluorescence spectra can be recorded for several excitation wavelengths and can be presented as 3-way data tables. The objectives of the data treatment are to describe and compare the samples by taking into account all the emission spectra, and to reveal characteristic excitation and emission wavelengths. Generalised Canonical Correlation Analysis has been tested on fluorescence emission spectra acquired for binary mixtures of raw materials in the food domain. The application of the method within the context of spectral data is presented.
