An organic product sold under Prince Charles's Duchy Originals brand has been found to contain elevated levels of a cancer-causing chemical.
Hand-fried vegetable crisps from the Prince's range are among a number of products identified as containing acrylamide in a study by the Food Standards Agency (FSA). Also on the list are Hula Hoops, Ryvita, Pringles and Tesco Ginger Nut biscuits.
Acrylamide is formed when starch-rich foods are fried, baked, grilled or toasted at high temperatures.
It has been found in a wide range of home-cooked and processed foods including potato crisps, French fries, bread, crispbreads and coffee.
Concerns about acrylamide first emerged in 2002 and food companies have made determined efforts to reduce the levels in their products.
The FSA has just published the results of the first survey in a three-year programme measuring the amounts of acrylamide and two other chemicals - furan and ethyl carbamate - in food.
