In the processing of a meat material in a metal mold of stainless steel, laminated means for substantially preventing the attack of the metal mold by the salts in the meat material, said means comprising (a) a layer of sacrificial metal less noble than the mold metal, said metal layer to be positioned at the end of the mold and held in generally full surface contact with the meat material and in electrical contact with the mold metal and (b) a layer of impermeable material between the metal mold and the layer of sacrificial metal in the area where the meat material is in contact with the layer of sacrificial metal for preventing contact of the sacrificial metal and mold in said area, said impermeable material having a character such as to prevent staining of the mold during sacrificing of the metal layer. A laminated anode for use in a metal mold of stainless steel during processing of a meat material in the mold to protect the mold surfaces in contact with the meat material against corrosive action, said anode being adapted to be placed and held between the mold and a cover therefor and being in strip form and flexible and including a layer of sacrificial metal less noble than the metal of the mold selected from the group consisting of aluminum, magnesium or zinc and a layer of impermeable material approved for use with food, wherein said sacrificial metal is in electrical contact with the mold and the meat material and said impermeable material being such as to protect the cover from sacrificial metal deposits and said strip being disposable after the processing of the meat material.
