Abstract

Cette invention concerne un indicateur de contamination des aliments, qui comprend une première couche servant de support imperméable, une deuxième couche et une troisième couche constituée d'un film de revêtement imperméable. La deuxième couche contient un matériau absorbant, qui permet l'écoulement direct de divers jus, un tampon pour une solution "d'immuno-perles", et une zone de détection. La couche capillaire, qui repose sur la couche de support imperméable, est recouverte par la troisième couche en film de revêtement imperméable: de cette manière, la couche capillaire réside entre la couche de support imperméable et la troisième couche en film de revêtement imperméable.
