"Also, we are keen to establish connectivity with companies, so we can get these compounds out into industry as quickly as possible," said project leader Joe Sweeney, who is Professor of Catalysis and Chemical Biology at the University.
Some of the best studied cancer-causing compounds are the heterocyclic aromatic amines (HCA). These are formed naturally in protein-rich food such as meat and fish during cooking, and are more likely to form if the meat is cooked for a long time and at ...
Not only is acrylamide formed in some starchy food but also meat cooked at high temperatures has as many as 20 compounds known as heterocyclic amines, or HCAs for short. HCAs are known as cancer causing chemicals. The higher the temperature that ...
