Colourful chemistry of canning

Research output: Contribution to specialist publicationArticle


Over the last 2 years, we have been interested in the variety colours observed when aqueous solutions of metal ions are added to plant extracts containing anthocyanins. We have focused on using materials that could be sourced and used easily at home. So far, we have found iron, copper and aluminium salts can form colourful complexes with aqueous anthocyanin extracts. Aluminium in particular can give impressive results.
