Metal alloys, especially stainless-steel, are widely used in the preparation, production and storage of food, because of their corrosion resistance and barrier properties. Most food contact (FC) stainless-steel articles are designed for repeated, long-term use, and the migration of heavy metals is regarded as the main safety risk when they make contact with food. Manganese (Mn) is an important alloying element in stainless-steel, and its potential to migrate has caused considerable consumer concern.
