Nanotechnologies in the food industry – Recent developments, risks and regulation

Recent research has highlighted the potential for nanotechnologies’ use in wide ranging food applications, including improving supplements, novel food packaging, increasing the range of food textures, colours and tastes, increasing the efficiency of liquid filters, cooking oil catalysation and targeted crop pesticides. Because of these new developments it is likely that radical changes in the way food is perceived, stored, packaged, transported, monitored, consumed and processed will come about. Available literature suggests that many uncertainties remain about nanomaterials, including the potential for bioaccumulation and potential human health risks. While proposed applications of nanotechnologies are wide and varied, developments are met with some caution, while progress may be stifled by lack of governance and potential risks.
