Kit for the determination of gluten contamination in a compound to be analyzed

Kit comprising a preparation solution configured to prepare a compound to be aiulysed, a sensor for the determination of gluten contamination in the compound, and a processing unit connected thereto The sensor comprises a base layer with a pair of electrodes, an upper layer with a membrane permeable to at least one gas releasable by the compound as a function of the concentration of at least one prolamin present in the compound, and a resistive layer, interposed between the base layer and the upper layer and configured to detect the gas released by the compound and permeated through the membrane and to change the resistivity thereof as a function of the gas detected The pair of electrodes is configured to detect a resistivity change in the resistive layer and to generate a sigiul as a function of the detected resistivity change
