    摘要: Provided is a device for treating a food product in order to reduce or eliminate the detrimental effects of the presence of oxygen which is in contact with the external surface of the product. The device includes a vat provided with a hood, containing a food product whose free surface is in contact with the atmospheric air, a solid electrolyte membrane, each face of the membrane being connected to an electrode, each electrode being connected to a current generator, a heater for making the electrolyte operate at the desired working temperature, a pump for discharging oxygen extracted, by the solid electrolyte, from the atmospheric air present above the food product, in a pipe, a pump for circulating the atmosphere to be treated, an oxygen analyzer for measuring the oxygen level in the gas atmosphere above the food product, a control unit for modifying the operation of the solid electrolyte as a function of the oxygen level and the gas atmosphere to be treated and the recirculation rate of the atmosphere and, optionally, a cooling unit.

    摘要: A process is provided for treating food products in order to reduce or eliminate the detrimental effects of the presence of oxygen in the atmosphere which is in contact with the products and, more particularly, the external surface of the products. A non-zero quantity of oxygen is extracted from the atmosphere by implementing a solid electrolyte which is an O2− ion conductor and is essentially impermeable to the gases. The invention has applicability to preserving frying oil baths.
