<p>PURPOSE:To prevent sulfur staining and the offensive odor of hydrogen sulfide getting trouble in the canning of food containing protein containing sulfur such as fishes, meats, beer or the like without changing the properties of content and contamination by a heavy metal. CONSTITUTION:A volatile sulfide and a substance forming a stable sulfide with sulfide ions are mixed into a coating layer between the metallic material of a metal-resin laminate, in which the coating layer having permeability to the volatile sulfide and water is laminated on the surface of the metallic material, and the coating layer. According to the method, a sulfide in canned food is taken into a can vessel, thus preventing the generation of sulfur staining and an offensive odor. Metallic salt, monosaccharide, fumaric acid salt, furfural, D-glucuronolactone and potassium bromate are cited as a substance forming the stable sulfide.</p> |
