Understanding acrylamide

Jan 27, 2017, 15:28 PM by System

Earlier this week there were stories in the press that the UK Food Standards Agency is warning that overcooked starchy foods can contain acrylamide, a chemical liked to cancer.

Risks during high temperature cooking

Recent concern over the presence of acrylamide in food dates from 2002. Scientists reported that up to “mg/kg” quantities of acrylamide could be formed in carbohydrate-rich foods during high-temperature cooking, e.g. during frying, baking, roasting, toasting and grilling. 

Acrylamide (or acrylic amide) is a chemical compound with the chemical formula C3H5NO. It is mainly formed in food by the reaction of asparagine (an amino acid) with reducing sugars (particularly glucose and fructose) as part of the Maillard Reaction (a complex series of reactions between amino acids and reducing sugars, usually at increased temperatures).

Since the 2002 discovery, major international efforts have been mounted to investigate the principal sources of dietary exposure, to assess the associated health risks and develop risk management strategies.

Codex code of practice

In 2009 the FAO/WHO Codex Alimentarius developed a “Code of Practice for the Reduction of Acrylamide in Foods” (CAC/RCP 67-2009) which intends to provide national and local authorities, manufacturers and other relevant bodies with guidance to prevent and reduce formation of acrylamide in potato products and cereal products.

How to reduce acrylamide?

  • Decrease the surface area; for example in French fries, by cutting potatoes into thicker slices.
  • Washing, blanching or par-boiling treatments can be employed to leach the asparagine/reducing sugar reactants from the surface of the potato before the cooking step.
  • Yeast fermentation of wheat bread doughs reduces the free asparagine content.
  • Where relevant, industry should endeavor to provide advice to consumers on appropriate cooking and handling instructions that can help to mitigate acrylamide formation in the product.

FAO Senior Food Safety Officer Markus Lipp explained the sources, the causes, and the risk from acrylamide and how FAO and WHO expert committees assess compounds in order to provide the best, most robust scientific advice available to Codex committees.

We examine the safety and ask what does it matter for humans in their daily lives?

At the heart of the Codex mandate are the core values of collaboration, inclusiveness, consensus building and transparency. Governmental and non-governmental, public and private organizations alike play a vital role in ensuring Codex texts are of the highest quality and based on sound science.

Codex would have little authority in the field of international standard setting if it did not welcome and acknowledge the valuable contributions made by observers. Expert technical bodies, industry and consumer associations contribute to the standard-setting process in a spirit of openness, collaboration and transparency.

Intergovernmental organizations (IGOs) and international non-governmental organizations (NGOs) can apply for observer status in Codex in order to attend and put forward their views at every stage of the standard-setting process.

Food is a sensitive commodity, which has travelled
around the world since ancient times.
We might not always know where it comes from,
but we expect it to be available, safe and of good quality.
