Our ChemPubSoc Europe Advent Calendar highlights articles from magazines of the ChemPubSoc Europe societies. Nachrichten aus der Chemie is the membership magazine of the German Chemical Society (Gesellschaft Deutscher Chemiker, GDCh). Dr. Christian Remenyi (pictured) is Editor-in-Chief of Nachrichten aus der Chemie.

Christian Remenyi chose Azofarbstoffe in Gummibärchen – aus Blau wird Gelb (Azo Dyes in Gummy Bears – Blue Becomes Yellow) by Matthias Ducci.

Why have you selected this article?

The article is part of a very successful chemistry education series in our magazine: In each issue, interesting experiments are presented which are applicable in chemistry classes; and in addition: I like Gummy Bears.

What is the article about?

In human beings, azo dyes are usually split into amines. Some of them are hazardous and that's why only some of these substances are permitted for food. Brilliant Black BN is one of the non-hazardous food dyes (known as E 151) and with it and Gummy Bears there are funny and instructive experiments in school possible.

Can you say one sentence about yourself, please?

I am a chemist, journalist, and Editor-in-Chief of Nachrichten aus der Chemie.

Thank you for sharing this article with us.
