Abstract

Procédé permettant de déterminer l'état de fraîcheur d'un nutriment, caractérisé en ce que(a) on met deux électrodes (1, 1') d'une sonde au contact du nutriment à tester (2),(b) on applique au moyen d'un générateur (3) de tension sinusoïdale produisant une tension Vgéné, dans ledit nutriment à travers lesdites électrodes un signal électrique périodique de référence, dénommé signal de référence Vréf, contrôlé en termes de tension et de courant à l'aide d'un moyen de contrôle (4) et traversant un moyen limiteur de courant (5),(c) on mesure le signal Vs obtenu aux bornes desdites électrodes,(d) on compare ledit signal Vs obtenu audit signal de référence Vréf.Le procédé de l'invention permet d'obtenir une indication quasi immédiate de la qualité du nutriment testé. Sa mise en oeuvre, très simple au moyen d'un dispositif portatif et peu onéreux, ne nécessite pas l'intervention d'un personnel qualifié.Method for determining the state of freshness of a nutrient, characterized in that (a) two electrodes (1, 1 ') of a probe are placed in contact with the nutrient to be tested (2), (b) one applies by means of a sinusoidal voltage generator (3) producing a voltage Vgéné, in said nutrient through said electrodes a periodic electrical reference signal, called reference signal Vref, controlled in terms of voltage and current by means of 'a control means (4) and passing through a current limiting means (5), (c) the signal Vs obtained at the terminals of said electrodes is measured, (d) said signal Vs obtained is compared with said reference signal Vref. of the invention makes it possible to obtain an almost immediate indication of the quality of the nutrient tested. Its implementation, very simple by means of a portable and inexpensive device, does not require the intervention of qualified personnel.
