Susceptors used for browning or crisping food prepared in microwave ovens and processes for the production of such susceptors. The susceptors are produced by laminating an anodizable metal (e.g. aluminum, tantalum, niobium, zirconium, titanium or tungsten) onto a suitable non-metallic substrate (e.g a heat resistant polyester film, a paperboard sheet or a glass, plastic or ceramic article) and anodizing the metal layer to form an anodic film covering a residual metal layer of suitable thinness to generate heat by resistance heating when irradiated by microwaves. The anodic film acts as a barrier to prevent the migration of any degradation products to the foodstuff undergoing the heating procedure. The susceptors can be used as wrappings for food items, as package inserts or as internal coatings on food containers and the like.
