Near infrared microscopy has shown potential to discriminate bone particles of fish origin and those of terrestrial animal origin in the sediment fraction of feedstuffs. In this study, the use of this method for the detection of processed animal proteins in the flotate is investigated. First, we show that it is possible to recognize animal particles in the flotate based on a spectral analysis. Secondly, the analysis of several spectra indicates that the near infrared microscopy could differentiate classes of animals.  4, fiche 1, Anglais, - near%20infrared%20microscopy

La microscopie en proche infrarouge (NIRM) a démontré son potentiel pour discriminer les particules d'os de poisson de celles des animaux terrestres dans la fraction sédimentée des aliments composés pour animaux. L'identification de traces de protéines animales transformées (PAT) par cette technique est basée sur l'évaluation des spectres obtenus à partir des particules individuelles présentes dans l'échantillon. Les présents travaux apprécient les performances du NIRM pour la détection des particules d'origine animale dans le flottât des aliments. Premièrement, il est montré qu'il est possible de reconnaître des particules d'origine animale dans le flottât sur base de leur spectre. Deuxièmement, l'analyse de plusieurs spectres indique que le NIRM pourrait différencier des classes d'animaux.  2, fiche 1, Français, - microscopie%20en%20proche%20infrarouge

Infrared microscopy is a specialized branch of optical (light) microscopy. It deals with the magnification of small objects either illuminated by or emitting radiation in the near infrared (750-1200 nm). Infrared microscopy differs from thermography, which is the detection and measurement of thermal radiation emitted from warm objects. It also differs from IR photography, which uses sensitive films or papers, but does not produce real-time images. The applications of IR microscopy fall into four primary areas. These are: 1. Study of materials that are opaque in the visible but transparent in the near IR... 2. Study of materials that are transparent in the visible but show absorptions or other contrasts in the near IR ... 3. Study of materials that absorb visible energy and reemit it as fluorescence or luminescence in the IR ... 4. Study of materials that are photosensitive in the visible, but nonresponsive in the IR ...  1, fiche 3, Anglais, - infrared%20microscopy
