20130112895 | Method for Characterising an Agri-Food Product and Device for Implementing Such a Method - The invention relates to a method for characterising one or more samples of an agri-food product, in particular intended for determining the naturality, freshness and authenticity of such a product and/or the conformity of same with a target product. The method of the invention is characterised in that it comprises: acquiring a plurality of natural fluorescence spectra of the sample; applying a multivariate or multi-path analysis method to said spectra, wherein said method provides a limited number F of variables representing said or each sample, in order to enable the representation thereof by a point (PE) in a space having F dimensions; calculating a distance (D) between said point representing said or each sample and a target (C | 05-09-2013 |

20120280146 | METHOD AND SPECTROSCOPIC ANALYSIS APPLIANCE, ESPECIALLY FOR ANALYSING FOOD, WITH MULTI-CHANNEL TREATMENT OF SPECTRAL DATA - The invention relates to a method for the spectroscopic analysis of at least one sample, using a method for analysing spectroscopic data based on a multi-channel statistical model, said method comprising: the illumination of said or each sample to be analysed by a plurality of luminous excitation rays with respective wavelengths; the acquisition and the pre-treatment of frontal fluorescence spectra, each spectrum corresponding to a respective luminous excitation ray; for each sample, the calculation of a score vector by applying said multi-channel statistical model to the pre-treated spectra; and the determination of at least one parameter selected from a quality indicator of said or each sample and a parameter characterising a method that has been applied to said or each sample, from said score vector; the method being characterised in that the average spectral distance between the luminous excitation rays is at least 50 nm, over a spectral range of at least 100 nm. The invention also relates to an appliance for implementing such a method. | 11-08-2012 |
