McGill researchers shed light on formation of carcinogen in food

03.02.2005


Furan, a potentially dangerous chemical has been found by Health Canada and the U.S. Food and Drug Administration (FDA) in processed foods, especially canned or bottled foods. A new study by McGill researchers Dr. Varoujan Yaylayan and graduate student Carolina Perez Locas explains the presence of this chemical in a wide range of food products



The study, published in the October, 2004 issue of Journal of Agricultural and Food Chemistry, shows how food-based amino acids and sugars break down when heated to produce furan. It also identifies other food components, such as vitamin C and polyunsaturated fatty acids, which may produce furan as an unwanted by-product of cooking, bottling or canning food products.

"Furan and its derivatives sometimes form when amino acids or sugars are broken down by the heat of cooking," explains Dr. Yaylayan. "Normally, furan is a volatile chemical which tends to quickly evaporate. However, when it cannot escape for some reason, for example if it is in sealed cans or jars, then it remains present in the food for some time."


While traces of furan and furan-containing products have been found in some processed and cooked products, especially canned and bottled foods, there’s no reason for consumers to change their shopping habits according to government health agencies. The quantities of furan in foods are well below what is considered dangerous.

Although furans have been linked to cancer in experimental animals, there is no direct evidence that furans are human carcinogens.

"Even so," says Dr. Yaylayan, "food companies and government agencies are keeping a close eye on the situation. It’s important to know exactly what chemicals are present in food, and to understand how they form during processing."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
