WHO warns of cancer causing chemical in hot chips

A CHEMICAL created when starchy foods are cooked at high temperatures has been proven to cause cancer, the World Health Organisation says.

The main foods in which the chemical acrylamide has been detected include fried or roasted potatoes, potato crisps, coffee and cereal-based products, including biscuits and toasted bread.

A joint WHO and United Nations expert committee on food additives agreed there was evidence that acrylamide caused cancer following laboratory tests in animals this year.

“Food Standards Australia New Zealand (FSANZ) has assessed the new data and agrees with the conclusions,” a FSANZ spokeswoman said.

“The authority has acknowledged there is a need for ongoing research into health impacts of acrylamide in food.

“The FSANZ has been working with industry to reduce the levels of acrylamide in food.”

Acrylamide is mainly formed in carbohydrate-rich foods by the reaction of asparagine (an amino acid) with reducing sugars (particularly glucose and fructose) during high-temperature cooking, usually in excess of 120C, such as baking, grilling or frying.

Methods that can decrease the amount of acrylamide in potato chips include increasing the surface area by cutting potatoes into thicker slices and washing, blanching or par-boiling to reduce the sugars in potatoes before frying.
