Titanium dioxide substitute inspired by «brilliantly white» beetle: «The pigment is 100% cellulose, nothing else»

Cambridge University spin-out Impossible Materials has developed a cellulose-based, white pigment to replace titanium dioxide in food applications.

Controversial colouring titanium dioxide (E171) has long attracted attention for its link to negative health consequences, including the development of cancer.

The contentious ingredient - currently used as colorant in products such as chewing gum, pastries, coffee creamer, food supplements, soups and sauces - is also harmful to the planet. 

On 7 August, titanium diocide will no longer be authorised as a food additive in the EU. Food makers are scrambling to find white pigment alternatives, and Cambridge University spin-out believes it has found the solution.
