摘要
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)stainlesssteel 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.
