Gluten-Free Claim Checker for Food Listings

Check gluten-free food claims against the ingredient list. The Gluten-Free Claim Checker flags products labeled 'gluten-free', 'no gluten' or 'without gluten' that list wheat, barley, rye, spelt, malt or other gluten grains, wheat starch without the FDA asterisk statement, unnamed flour, gluten test values over 20 ppm, and EU wording problems like 'low gluten' or 'suitable for coeliacs' on its own, under FDA 21 CFR 101.91 and EU Regulation 828/2014. Works with grocery scraper output and Open Food Facts data. Click Start with the prefilled example to see it work.

This is an automated comparison of the claims and ingredients you supply, not a legal determination or a gluten test. It can't measure gluten or see package images. A clean result doesn't mean a product is safe for people with coeliac disease. Not legal or medical advice; every row carries this disclaimer and a timestamp.

What does the Gluten-Free Claim Checker do?

• ✅ Gluten grains in gluten-free products: wheat, rye, barley, spelt, kamut, durum, semolina, farro, triticale, bulgur, couscous, seitan, malt and malt extract (21 CFR 101.91(a)(3)).
• ✅ Wheat starch or 'Contains wheat' without the exact FDA statement 'The wheat has been processed to allow this food to meet the Food and Drug Administration (FDA) requirements for gluten-free foods' (21 CFR 101.91(b)(3)).
• ✅ Unnamed 'flour' in gluten-free products, and gluten values of 20 ppm or more (US) or over 20 mg/kg (EU); 'very low gluten' over 100 mg/kg.
• ✅ EU wording: 'low gluten' or 'reduced gluten' (not permitted), 'suitable for coeliacs' without 'gluten-free', and oats not stated as specially produced (Regulation 828/2014).
• ✅ Info notes for fermented or hydrolyzed ingredients, oats (US) and 'may contain' statements.
• ✅ Skips false friends: buckwheat, wheatgrass, rice malt, maltodextrin, 'free from wheat, barley and rye', 'not gluten free' and 'gluten-free options available'.
• ✅ Output per row: market, claimFound, glutenSources, glutenPpm, riskLevel, issueCount, issues (ruleId, severity, message, quote, sourceUrl, fixHint), checkedAt and a disclaimer.

How much does it cost to check gluten-free claims?

This Actor uses pay-per-event pricing: $0.002 per product saved plus a $0.00005 start fee per run, plus small platform usage paid by you (a few hundredths of a cent for small runs). That's about $2.00 for 1,000 products and $20.00 for 10,000 plus usage. With Only save rows with findings on, rows without findings aren't saved or charged. You can set a maximum cost per run in the run options.

How it works

Checks are deterministic rules written from FDA's gluten-free labeling rule (21 CFR 101.91, as amended in 2020 for fermented and hydrolyzed foods) and Commission Implementing Regulation (EU) No 828/2014, checked on 2026-11-03. Ingredient lists are split into ingredients and matched against gluten-grain names in English, German, French, Spanish and Italian. No AI and no external calls.

FAQ

Are oats allowed in gluten-free food?

In the US oats aren't a gluten-containing grain under 101.91, but the whole food must test below 20 ppm. In the EU, oats in gluten-free food must be specially produced to avoid contamination and contain no more than 20 mg/kg gluten.

Is wheat starch allowed?

It can be, if the food stays below 20 ppm. In the US, 'wheat' in the ingredients or a 'Contains wheat' statement then needs an asterisk and the exact FDA statement.

Does it test gluten?

No. It compares claims with the ingredients and any test value you supply.

Is it AI?

No. It's a fixed set of rules, so the same input always gives the same result.

Limitations

• Ingredients and text only; no lab testing.
• Ingredient names in languages other than EN, DE, FR, ES and IT may be missed.
• Cross-contact can't be detected from text.
