Can coatings for foods and beverages: issues and options

Canned foods and beverages constitute a major part of the global food supply. Consumers expect canned foods and beverages to maintain their flavour, texture and colour and be free of illness-causing pathogens. This is generally accomplished by coating can interiors with protective resins. With recent calls for the removal of commonly used epoxy resins, an understanding of the availability, technological feasibility and health profiles of alternative coating options is needed. Some of this information is publicly available but more research and dialogue are needed in order to make informed decisions about coating alternatives’ technological feasibility, risks and benefits.
