Introduction
Acrylamide is a process contaminant that can form naturally in certain foods when they are cooked or processed at high temperatures.
It is mainly formed through the Maillard reaction, involving naturally occurring reducing sugars and the amino acid asparagine, particularly during frying, baking and roasting. Formation is favoured by high temperatures and relatively low moisture conditions.
Acrylamide is particularly relevant to products such as:
- Potato-based foods
- Bread and bakery products
- Biscuits and cookies
- Breakfast cereals
- Coffee and coffee substitutes
- Crackers and crisp breads
- Cereal-based snacks
- Certain processed foods
The European Union has established specific mitigation measures and benchmark levels to reduce acrylamide formation in food. For manufacturers and exporters, understanding the distinction between a benchmark level and a legally enforceable maximum limit is essential.
What Is Acrylamide?
Acrylamide is a chemical compound that can form in food during high-temperature processing.
Unlike contaminants that enter food primarily from environmental or agricultural sources, acrylamide is largely a process-generated contaminant.
The main formation pathway involves the reaction between:
Reducing sugars + Asparagine + Heat → Acrylamide
The reaction becomes particularly relevant during processing temperatures generally above approximately 120°C under low-moisture conditions.
Consequently, processing conditions can have a significant effect on the final acrylamide concentration.Why Is Acrylamide a Food-Safety Concern?
The toxicological concern surrounding acrylamide is primarily related to its potential genotoxicity and carcinogenicity.
EFSA’s scientific assessment concluded that dietary exposure to acrylamide is a concern with respect to carcinogenic effects.
The risk is influenced by:
- Amount consumed
- Frequency of consumption
- Acrylamide concentration in the food
- Individual dietary patterns
- Age and exposure duration
Because acrylamide can occur across several commonly consumed food categories, reducing its formation is an important food-safety objective.
How Does Acrylamide Form in Food?
Acrylamide formation depends on several interconnected factors.
1. Raw Material Composition
The natural concentration of:
- Asparagine
- Glucose
- Fructose
- Other reducing sugars
can influence acrylamide formation.
2. Temperature
Higher processing temperatures can increase acrylamide formation.
3. Processing Time
Longer exposure to high temperatures may increase formation, although the relationship depends on the specific food and process.
4. Moisture
Low-moisture conditions generally favour acrylamide formation during thermal processing.
5. pH
Processing pH can influence the chemical reactions involved.
6. Recipe and Formulation
Ingredients, additives and processing aids can influence the formation potential.
7. Processing Method
Frying, baking and roasting can produce different acrylamide concentrations depending on the process parameters.
Foods Commonly Associated with Acrylamide
Acrylamide is particularly relevant to foods containing carbohydrates and asparagine that undergo high-temperature processing.
Potato-Based Products
Examples include:
- French fries
- Potato chips
- Potato crisps
- Other fried potato products
Potato-based foods are among the important contributors to dietary acrylamide exposure.
Cereal-Based Products
Examples include:
- Bread
- Biscuits
- Cookies
- Crackers
- Breakfast cereals
- Cereal snacks
- Bakery products
Coffee
Coffee and coffee substitutes are also significant sources of dietary acrylamide exposure.
EU Regulatory Framework for Acrylamide
The European Union introduced a specific regulatory framework through:
Commission Regulation (EU) 2017/2158 of 20 November 2017 establishing mitigation measures and benchmark levels for the reduction of the presence of acrylamide in food.
The regulation is currently in force and establishes measures that food business operators must apply to reduce acrylamide formation.
The framework covers relevant food categories and establishes:
- Mitigation measures
- Benchmark levels
- Monitoring requirements
- Sampling and analysis provisions
- Responsibilities for food business operators
Benchmark Levels Are Not Maximum Legal Limits
This distinction is extremely important.
The EU acrylamide values are referred to as benchmark levels, rather than conventional maximum legal limits.A benchmark level is used as an indicator for assessing whether mitigation measures are effective and whether further reduction should be considered.
Therefore:
Exceeding a benchmark level does not automatically mean that a food is illegal.
However, a result above the applicable benchmark should trigger appropriate review of the mitigation measures and processing controls.
Food businesses should therefore avoid describing EU acrylamide benchmark levels as simple “maximum permitted limits.”EU Acrylamide Benchmark Levels
The EU framework establishes benchmark levels for specific food categories.
Examples of categories covered include:
Important: Benchmark levels are commodity-specific and may be revised. Manufacturers and exporters should always check the latest applicable version of Commission Regulation (EU) 2017/2158 and associated EU guidance before making a compliance decision.
EU Mitigation Measures
One of the key features of the EU approach is that businesses are expected to focus on prevention and reduction at the processing stage.
Depending on the food category, mitigation can involve controlling:
- Raw material selection
- Agricultural practices
- Recipe composition
- Ingredient selection
- Processing temperature
- Processing time
- Moisture
- Frying conditions
- Baking conditions
- Roasting conditions
- Finished-product colour
- Storage and preparation conditions
The objective is to reduce acrylamide formation while maintaining the intended quality, safety and sensory characteristics of the product.
Raw Material Selection
Raw materials can significantly influence acrylamide formation.
For example, potato varieties can differ in their levels of reducing sugars and therefore their acrylamide-forming potential.
Similarly, cereal ingredients can vary in their composition. Manufacturers may therefore consider:- Raw material specifications
- Supplier qualification
- Variety selection
- Storage conditions
- Seasonal variability
- Reducing sugar levels
- Asparagine-related risk
A raw-material control programme can be an important first step in reducing acrylamide formation.
Processing Controls for Acrylamide Reduction
Frying
Control of:
- Frying temperature
- Frying time
- Oil condition
- Potato preparation
- Final product colour
Baking
Controls may include:
- Baking temperature
- Baking time
- Dough formulation
- Moisture
- Product thickness
- Final colour
Roasting
For coffee and other roasted products, roasting conditions can significantly influence acrylamide formation.
Recipe Optimisation Reducing acrylamide precursors or using suitable ingredients may help lower formation without compromising product quality.Why Product Colour Can Matter
In certain food categories, excessive browning can be associated with increased acrylamide formation.
Therefore, controlling the final degree of browning can be one practical mitigation measure.
However, colour alone cannot be used as a substitute for laboratory testing.
Two products with similar visual appearance can have different acrylamide concentrations depending on raw materials and processing history.Acrylamide Testing
Laboratory testing provides quantitative information about the actual acrylamide concentration in a food product. Testing can be used for:
- Product development
- Process validation
- Supplier qualification
- Routine quality control
- Regulatory monitoring
- Export compliance
- Investigation of elevated results
- Verification of mitigation measures
Testing is particularly useful when a manufacturer needs to determine whether changes in formulation or processing have actually reduced acrylamide formation.
Analytical Methods for Acrylamide
Acrylamide occurs at relatively low concentrations, requiring sensitive analytical techniques.
LC-MS/MS
Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) is a highly selective technique that can be used for trace-level acrylamide determination in food matrices.
It is suitable for a wide range of food products when supported by an appropriate validated method.
GC-MS/MS
Gas chromatography-based approaches may also be used depending on the analytical method and sample matrix.
Method Selection
The analytical method should be appropriate for:
- Food matrix
- Expected concentration
- Required reporting limit
- Applicable regulatory or customer requirement
- Laboratory validation status
Important Analytical Considerations
Acrylamide testing requires appropriate sample preparation and analytical controls.
Important performance characteristics include:- Specificity
- Selectivity
- Accuracy
- Precision
- Recovery
- Linearity
- Limit of Detection (LOD)
- Limit of Quantification (LOQ)
- Matrix effects
- Measurement uncertainty
- Quality-control performance
The laboratory should establish an LOQ suitable for the benchmark level or customer specification being evaluated.
Sampling Is Important
A representative sample is essential for meaningful acrylamide analysis.
The sample should represent the production batch or lot being assessed.
Sampling considerations may include:- Batch size
- Product variability
- Different production lines
- Different processing conditions
- Packaging or lot segregation
- Homogenisation requirements
A laboratory result is only as representative as the sample submitted for analysis.
Risk-Based Acrylamide Monitoring
Acrylamide testing should ideally form part of a broader risk-management programme.

Acrylamide and Food Export Compliance
Acrylamide is particularly important for businesses exporting processed foods to the European market.
Products that may require consideration include:- Potato snacks
- Biscuits
- Bakery products
- Breakfast cereals
- Coffee
- Cereal-based foods
- Processed potato products
- Infant and young-child foods
Exporters should not rely only on general food-safety certificates.
Where acrylamide is relevant to the destination-market requirements or buyer specification, product-specific analytical evidence and process controls may be necessary.Acrylamide Requirements in India
India’s regulatory framework for acrylamide continues to develop.
FSSAI currently lists “Limits of Acrylamide as a contaminant in food chain” among standards under development.
FSSAI has also conducted national food surveys involving acrylamide, demonstrating regulatory and surveillance interest in this process contaminant.
Therefore, Indian manufacturers supplying domestic and export markets should monitor applicable FSSAI developments while separately assessing destination-market requirements.
For export-oriented businesses, EU requirements may currently be more operationally significant because the EU has an established acrylamide mitigation and benchmark-level framework.Acrylamide vs Other Food Contaminants
Acrylamide differs from contaminants such as:
Mycotoxins: Primarily produced by moulds.
Pesticide residues: Result from agricultural pesticide use.
Heavy metals: May originate from environmental contamination, raw materials or processing.

Conclusion
Acrylamide control is fundamentally a process-control challenge supported by analytical verification.
For food manufacturers, simply testing the finished product is not enough. Effective management requires understanding the raw materials, identifying the factors that promote acrylamide formation, optimising thermal processing and periodically verifying results through laboratory analysis.
For businesses exporting to the European Union, understanding the distinction between EU benchmark levels and maximum legal limits is particularly important. A practical approach is:
Identify the Risk → Control the Raw Materials → Optimise the Process → Test the Product → Monitor Trends → Take Corrective Action
With appropriate process controls and laboratory testing, manufacturers can reduce acrylamide formation, strengthen food-safety programmes and support compliance with international market requirements.
