Title (EN) ONLINE RECORDING OF WAVELENGTH ABSORPTION SPECTRA IN MEAT
(FR) ENREGISTREMENT EN LIGNE DE SPECTRES D'ABSORPTION DE LONGUEUR D'ONDE DANS LA VIANDE
Abstract:
(EN) The invention relates to invasive, optical measurements of meat products, and provides both a method and an apparatus for performing such measurements. The invention provides online, in-situ recording of a plurality of consecutive absorption spectra at different positions in meat products, performed without removing a sample from the meat product. This is an advantage since in inhomogeneous products, the position correlated to each spectrum allows for extraction of both average values for larger regions as well as specific values characteristic for smaller individual portions. In a preferred embodiment, a probe (1) with two knifes (4, 5) comprising light guiding means and light collecting means for recording infrared absorption spectra of portions between them, as well as means (14, 15, 46, 47) for determining an insertion depth of the probe (1) into the product. Much more precise and detailed classification or grading information for the meat product can be obtained with the invention.
(FR) L'invention concerne des mesures optiques et invasives de produits carnés et propose à la fois un procédé et un appareil pour la réalisation de telles mesures. L'invention permet un enregistrement in situ, en ligne d'une pluralité de spectres d'absorption consécutifs en des positions différentes dans les produits carnés, enregistrement réalisé sans prélever d'échantillon dans le produit carné. Ceci constitue un avantage dans la mesure où dans les produits non homogènes, la position corrélée à chaque spectre permet l'extraction à la fois de valeurs moyennes pour des régions plus importantes et de valeurs spécifiques caractéristiques pour des portions individuelles plus petites. Selon un mode de réalisation préféré, une sonde (1) avec deux couteaux (4, 5) comprend un moyen de guidage de lumière et un moyen collecteur de lumière pour enregistrer des spectres d'absorption infrarouge de portions entre eux, de même que des moyens (14, 15, 46, 47) déterminant une profondeur d'insertion de la sonde (1) dans le produit. L'invention permet d'obtenir des informations de classement et de notation beaucoup plus précises et détaillées pour le produit carné.
