Acrylamide Mitigation: EU 2017/2158 Benchmark Levels and the Programme Behind Them

Acrylamide forms in the Maillard reaction when reducing sugars meet free asparagine at temperatures above ~120 °C — exactly the conditions that make bread crusts, biscuits, fries, crisps, breakfast cereals and roasted coffee taste the way they do. EU Regulation 2017/2158 sets binding benchmark levels and a mandatory list of mitigation measures for food business operators across nine product categories. FDA's 2016 final guidance and Codex CXC 67-2009 cover the same chemistry without binding numerical limits. For bakery, snack, cereal, coffee and processed-potato manufacturers selling into the EU — or any market where retailer specifications follow EU benchmarks — acrylamide is a discipline you operate, not a test you pass. This guide is the operating manual.

What EU 2017/2158 actually requires

Commission Regulation (EU) 2017/2158 entered into force 11 April 2018 and applies directly across the EU and (via retained law and equivalent UK statutory instrument) the UK. It does three things. First, it sets benchmark levels — performance reference values, not maximum limits — for nine categories: fried potato products, potato crisps, soft bread, breakfast cereals, biscuits and wafers, crackers and crispbread, gingerbread, coffee (roasted and instant separately), and baby/young-children foods. Second, it lists mandatory mitigation measures by category — raw-material selection, recipe controls, processing controls, and final product controls. Third, it requires food business operators to sample and analyse their products to verify mitigation is effective. Exceeding the benchmark is not an automatic non-compliance — but it triggers a review and additional mitigation, which competent authorities will inspect.

The benchmark levels you actually operate to

Selected benchmark levels (μg/kg) from Annex IV: french fries (ready to eat) 500; potato crisps 750; soft wheat bread 50, soft non-wheat bread 100; breakfast cereals (excl. porridge) bran/wholegrain 300, wheat/rye 300, maize/oats/spelt/barley/rice 150; biscuits and wafers 350; crackers (excl. potato) 400; gingerbread 800; ginger biscuits 1000; coffee (roasted) 400; coffee (instant) 850; coffee substitutes (cereal-based) 500, chicory-based 4000; baby foods (excl. processed cereal-based) 40; processed cereal-based baby foods (excl. biscuits and rusks) 40, biscuits/rusks for infants 150. Infant categories are intentionally low — children eat more per kg body weight and the toxicology margin is smaller. The 2019 amendment ((EU) 2019/1888) added the explicit infant-biscuit benchmark.

Mandatory mitigation by category — the four levers

Annex I of 2017/2158 lists mandatory mitigation by category. Four levers recur across every product. Raw-material selection: low-asparagine wheat for bakery, low-reducing-sugar potato varieties for fries and crisps, storage above 6 °C for potatoes to prevent reducing-sugar accumulation. Recipe and formulation: replacing ammonium bicarbonate with sodium bicarbonate in biscuits, controlling fructose/glucose, calcium addition, and (the most effective single intervention for bakery and biscuits) asparaginase enzyme to convert asparagine to aspartic acid before baking. Process controls: lower-end-of-spec baking time and temperature, end-colour control (acrylamide tracks browning — L*a*b* or photometric colour measurement is the in-line proxy), avoiding overcooked product. Final product controls: visual or instrumented colour sorting to remove dark pieces, blanching for potato products, equilibration after frying.

Sampling and analysis — frequency and method

Article 4 requires sampling and analysis by the food business operator at a frequency proportionate to the production volume and product variability. There is no fixed frequency in the regulation — Member State guidance (notably the Dutch NVWA and German BfR documents) suggests a minimum of one sample per product line per year for low-volume sites and quarterly for high-volume. The reference method is LC-MS/MS to ISO 17025-accredited laboratories; ELISA-based screening is acceptable for in-process and trending but not for regulatory compliance evidence. Results must be retained for at least three years.

How EU 2017/2158 aligns with FDA, Codex and retailer specs

FDA's 2016 final guidance 'Acrylamide in Foods' is non-binding but recommends essentially the same mitigation toolkit — recipe, raw-material, process and final-product controls. Codex CXC 67-2009 is the international Code of Practice and is the basis of most retailer specifications outside the EU. UK retained law (the Contaminants in Food (Amendment) (EU Exit) Regulations 2020) mirrors EU 2017/2158. Major retailer specifications (Tesco, Sainsbury's, Lidl, Aldi, Carrefour, Edeka, Walmart for EU supply) reference the EU benchmarks directly or impose tighter internal limits. Holding to EU benchmarks therefore covers FDA, Codex and most retailer asks in one programme.

Frequently asked

Is the EU benchmark a legal limit?

No. Benchmark levels under EU 2017/2158 are 'indicators of performance' — exceeding them is not in itself non-compliance. But the regulation requires you to review and improve mitigation when you exceed, and competent authorities use repeated or unaddressed exceedances as the trigger for enforcement. In practice retailers treat benchmarks as ceilings.

Does asparaginase work for every bakery product?

It's the single most effective intervention for biscuits, crackers, soft bread and gingerbread — typical reductions of 50–90% — because the enzyme converts free asparagine before the Maillard reaction can use it. It is less effective in deep-fried potato products where the chemistry runs faster than the enzyme can act, and not relevant to coffee. Cost and dough-handling impact need to be evaluated by the R&D team.

How does this apply to infant foods?

Annex IV sets a 40 μg/kg benchmark for baby foods (excluding processed cereal-based) and processed cereal-based baby foods, and a 150 μg/kg benchmark for biscuits and rusks for infants. Infant categories are deliberately low — operate well below benchmark, sample more frequently, and document raw-material qualification. EFSA has also flagged infant exposure as a continuing concern, so retailer asks are typically tighter than the regulation.

Do US-only manufacturers need to comply?

Not legally — FDA has not adopted binding limits — but FDA's 2016 guidance and the 2010 Action Plan are the basis of FDA Compliance Program 7321.002 inspections, and major US retailers (Walmart, Costco, Whole Foods) and infant-food brands have adopted EU-equivalent internal limits since the 2010s. If you sell into private label or supply infant foods, expect EU 2017/2158 benchmarks to appear in the retailer specification.
