Acrylamide as Carcinogen

Acrylamide, is a substance that has been long suspected to be having carcinogenic potential. Though till now it has not been implicated in any of the cancers in man. It causes cancer in test animals, but it has not been proved to do so in human beings. Still, Swedish scientists have said that foodborne acrylamide might be responsible for several hundred cases of cancer in that country each year.

Acrylamide is used to produce plastics and dyes and to purify drinking water. Although traces have been found in water, no one expected high levels to be in basic foods.

Swedish scientists had made a surprise announcement in the spring that high levels of the possible carcinogen are in numerous everyday foods like - french fries, potato chips, some types of breakfast cereals and breads -- plenty of high-carbohydrate foods that are fried or baked at high temperatures. The chemical was not found in boiled foods, which are cooked at lower temperatures.

Now, Scientists have found a clue to the chemical reaction that may cause potato chips, French fries and other fried or baked starchy foods to build up high levels of a possible cancer-causing substance.                                                                                       

  
   

Asparagine, a naturally occurring amino acid , when heated with sugars such as glucose, leads to the formation of the substance acrylamide. This is called the Maillard reaction. This occurs at temperatures above 100°C (180°F).

Elevated levels of acrylamide have been found by the World Health Organization in home-cooked as well as pre-cooked, packaged and processed foods.

The U.S. Food and Drug Administration has made studying acrylamide's risk and determining how to lower its levels in food one of its highest research priorities.

 
 

The research was published in the journal Nature.
