Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is acrylamide, and how does it form in food?

    Model answer

    Acrylamide is a chemical that forms when starchy foods are cooked at high temperatures. The amino acid asparagine reacts with reducing sugars in the Maillard reaction.

  2. 2

    Under what cooking conditions does acrylamide form?

    Model answer

    Acrylamide forms mainly above about 120 °C in low-moisture conditions. High-temperature frying, baking, roasting and toasting produce it, while boiling does not.

  3. 3

    Which foods contribute most acrylamide to the diet?

    Model answer

    Chips, crisps, toast, breakfast cereals, biscuits and coffee are major sources. Potato and cereal products are the main contributors.

  4. 4

    Why is acrylamide considered a risk to public health?

    Model answer

    Acrylamide causes cancer in laboratory animals and is classed as a probable human carcinogen. High exposure can also damage the nervous system.

  5. 5

    What did EFSA conclude about acrylamide in 2015?

    Model answer

    EFSA concluded that acrylamide in food potentially increases the risk of cancer for consumers of all ages. The finding shaped EU controls on food businesses.

  6. 6

    Why can no safe level of acrylamide intake be set?

    Model answer

    Acrylamide is genotoxic, meaning it can damage DNA. Any exposure may carry some risk, so intake should be as low as reasonably achievable.
