A food container on which surface titanium oxide particles are fixed, where titanium oxide particles may contain brookite crystals, the material of which the food container is constructed may be stainless steel, and the titanium oxide particles may be bonded using a sintering aid, a binder or both. When the food container is made of glass, satisfactory mechanical strength of the container can be maintained even when the thickness of a wall of the container is reduced. Since titanium oxide particles can be fixed onto a surface of a food container at a temperature as low as 20 to 450° C. by use of a sintering aid, a binder or both thermal deformation of glass forming the food container can be prevented.
A food container comprising a container having titanium dioxide particles on a surface thereof, wherein the titanium dioxide particles are fixed on the surface by use of a sintering aid or both a binder and sintering aid, and wherein the sintering aid is at least one Broensted acid selected from the group consisting of phosphoric acid and an organic carboxylic acid and present in an amount of 10 to 10,000 ppm based on the titanium dioxide and wherein the titanium dioxide particles contain brookite crystals.
A method for producing a food container comprising fixing titanium dioxide particles on a surface of the container by use of a sintering aid or both a binder and a sintering aid, and wherein the sintering aid is at least one Broensted acid selected from the group consisting of phosphoric acid and an organic carboxylic acid and present in an amount of 10 to 10,000 ppm based on the titanium dioxide and wherein the titanium dioxide particles contain brookite crystals.
