A variety of substances have been found to migrate from paper and board packaging into dry foods. A new study by Emma Bradley and colleagues investigates the impact of different food types, paper and board packaging materials, and substance characteristics on migration levels. The researchers from the UK Food and Environment Research Agency compared migration of a variety of substances into real foods in contrast to migration into the dry food simulant TenaxTM, and assessed the effect of home processing steps such as peeling, washing and cooking on contaminant levels. They found migration to depend mostly on substance properties and food type, as well as contact area between the packaging and the food. Paper and board type had only a minor effect on the migration levels.
