Acrylamide Monitoring in Baked and Fried Foods

Introduction
Acrylamide is an undesirable heat-induced contaminant that forms in carbohydrate-rich foods during baking, frying, roasting, or toasting at temperatures exceeding 120°C. It is produced primarily through the Maillard reaction a chemical reaction between reducing sugars (glucose, fructose) and the amino acid asparagine that also contributes to browning and flavor.

Since its discovery in foods in 2002, acrylamide has been a major focus for food safety authorities worldwide due to its classification as a probable human carcinogen (Group 2A) by the International Agency for Research on Cancer (IARC). Chronic exposure may increase risks of neurological, reproductive, and genotoxic effects.

At Eurofins Food Testing Laboratories, we provide comprehensive acrylamide monitoring and control services combining state-of-the-art analytical technologies, scientific expertise, and regulatory guidance to help manufacturers meet compliance and reduce consumer risk.
How Acrylamide Forms in Foods
Acrylamide formation depends on a complex interplay of precursor concentration, temperature, moisture, and cooking time.

Health Implications
- Carcinogenicity: Acrylamide and its metabolite glycidamide bind to DNA, potentially causing mutations.
- Neurotoxicity: Chronic exposure affects the nervous system, leading to coordination issues.
- Reproductive toxicity: Animal studies indicate hormonal and fertility impacts at high doses.
- Regulatory concern: Recognized as a genotoxic carcinogen no safe threshold is established.
Regulatory Framework
FSSAI Stance on Acrylamide
Acrylamide is not explicitly listed with a specific permissible limit in the FSSAI 2023 Compendium of Contaminants, Toxins, and Residues. Instead, it is managed through process hygiene and preventive manufacturing controls for foods prone to acrylamide formation, such as biscuits, bread, snacks, potato products, and coffee.
Under Section 16(5) (March 2024) on “Approved Processing Aids,” FSSAI mandates enzymatic treatments, specifically glucose oxidase and asparaginase, to reduce acrylamide in cereal- and potato-based foods during baking and frying. These enzymes, listed in Appendix C (Tables 11 and 11A), are permitted under Good Manufacturing Practice (GMP) residue levels, ensuring no toxic remnants in the final product.
EU Regulation on Acrylamide in Baked and Fried Foods
The European Union regulates acrylamide under Commission Regulation (EU) No. 2017/2158, effective since April 11, 2018. This regulation mandates food business operators (FBOs) to implement mitigation measures and adhere to benchmark levels to control acrylamide in foods such as French fries, potato crisps, bread, breakfast cereals, biscuits, coffee, and baby food. The goal is to keep acrylamide levels as low as reasonably achievable (ALARA) through preventive measures and testing protocols.

Case Study: Acrylamide Reduction in Biscuits
Challenge: A major biscuit exporter to the EU faced repeated non-compliance due to acrylamide exceedance.
Eurofins conducted raw material precursor screening using LC-MS/MS to trace sources linked to elevated asparagine and sugar levels. Through targeted process optimization—adjusting baking temperature, pH, and formulation, along with the use of asparaginase enzyme—acrylamide levels were reduced from high to within safe international limits. The biscuits maintained their signature taste, color, and texture, restoring compliance and ensuring consistent export acceptance.
