Benzene in cherry flavor - where it comes from and how to avoid it?

Flavorings containing benzaldehyde can develop benzene under the influence of light

30-Mar-2020

In 2013, the Stiftung Warentest found harmful benzene in drinks with cherry flavor. But how did the substance get into the drinks? Was the source benzaldehyde, an essential component of the cherry flavoring? And if so, how could the problem be solved? A new study by the Leibniz-Institute for Food ...

'Tricking' bacteria into hydroxylating benzene

15-Jun-2018

Breaking carbon-hydrogen bonds is notoriously difficult in lab chemistry, yet nature does it effortlessly. Now, scientists have used E.coli bacteria to oxidize the C-H bonds in benzene to generate phenol, with a genetically inserted enzyme (cytochrome P450BM3), that originally evolved to target ...

'Parachuting' boron on benzene rings

A bulky catalyst induces pinpoint targeting on benzene to create bioactive molecules

16-Apr-2015

Tuning the para position of benzene moieties is significant for creating biologically active compounds and optoelectronic materials. Yet, attaching a functional handle specifically at the para position of benzene has been challenging due to multiple reactive sites on the ring. Chemists at ITbM, ...
