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

Sensor for determining gluten contamination in a compound to be analysed,characterised in thatit comprises:- a base layer comprising at least one electrode;- an upper layer comprising a membrane that is permeable to at least one gas releasable from the compound according to the concentration of at least one prolamin present in the compound;- a resistive layer, interposed
between the base layer and the upper layer configured to detect the gas released from the compound and permeated through the membrane of the upper layer,wherein:- the resistive layer is configured to vary its own resistivity as a function of the gas detected, and- the electrode is configured to detect a change in resistivity of the resistive layer and to generate a signal as a function of the detected change in resistivity.
