Acrylamide

Description

Acrylamide: What it is and why it matters

What is acrylamide

• Acrylamide is a chemical compound that can form in certain starchy foods when they are cooked at high temperatures. It is also used industrially as a monomer to make polyacrylamide polymers.
• It is not an ingredient added to foods; it develops naturally during cooking, especially with browning.

How it forms in foods

• Acrylamide forms mainly through the Maillard reaction between reducing sugars and the amino acid asparagine.
• Typical formation occurs in carbohydrate-rich foods cooked at temperatures above about 120°C (248°F), such as frying, baking, or roasting.
• The amount formed increases with higher temperature and longer cooking times, and with browning levels.

Foods that tend to have higher acrylamide

• Fried potatoes (French fries, potato chips)
• Toasted or deeply browned bread and breakfast cereals
• Other baked or fried starchy foods (biscuits, crackers, certain snack foods)

Health considerations

• The International Agency for Research on Cancer (IARC) has classified acrylamide as possibly carcinogenic to humans (Group 2A). This means there is some evidence from animal studies and limited human data, but there is no definitive proof of cancer risk in people.
• Acrylamide can cause neurotoxic effects in animals at high exposure levels; human evidence for neurotoxicity at typical dietary amounts is less clear.
• Regulatory agencies emphasize that while there is potential risk, it is prudent to minimize exposure as part of a balanced diet.

How to reduce acrylamide exposure at home

1. Cook to a light golden color, not dark brown
   • Aim for a light golden yellow hue rather than deep brown in fried or baked items.
2. Use shorter cooking times and lower temperatures when possible
   • Avoid excessive browning or long frying times.
3. Prepare potatoes in a way that reduces sugar content
   • Soak cut potato pieces in water for about 15–30 minutes, then dry thoroughly before frying or roasting.
   • Soaking reduces reducing sugars available for acrylamide formation.
4. Store potatoes and other products appropriately
   • Store raw potatoes in a cool, dark, well-ventilated place.
   • Avoid long-term refrigeration of raw potatoes intended for frying or roasting, as cold storage can increase sugar levels and acrylamide formation.
5. Diversify cooking methods
   • Boiling or steaming potatoes and other starches typically results in lower acrylamide formation than frying or baking.
6. Balance your diet
   • A varied diet with plenty of fruits, vegetables, and whole grains helps minimize overall exposure from any single source.

Regulatory and guidance context

• Many regions have issued guidance and mitigation strategies to reduce acrylamide in foods. In the European Union, food businesses follow mitigation measures and benchmark levels to minimize acrylamide formation during processing and cooking.
• Agencies like the FDA and EFSA continually assess the risk and provide consumer guidance on cooking practices and dietary intake to help reduce exposure.

Quick takeaway

• Acrylamide forms in certain foods when they are cooked hot and browned. It is not an added ingredient but a byproduct of cooking.
• You can reduce your exposure by cooking foods to a lighter color, soaking and drying certain foods before cooking, using gentler cooking methods, and storing ingredients appropriately.
