Abstract
Plastic packaging is used for the containment of many dry foods. The United States Food and Drug Administration requires no migration testing of the packaging used for dry foods having no free oils on their surface. We illustrate with numerous examples that migration of additives from plastic packaging does, however, occur to such dry foods. Migration rates to these dry foods are lower than to food oils but are significantly higher than to water. It is suggested that activated carbon or alumina power could be used as a simulant for many dry foods.
