Understanding Cornflour and Gluten
Cornflour, also known as cornstarch in some regions, is a fine powder derived from the starchy endosperm of corn kernels. Since corn (or maize) is a grain that does not contain gluten, pure cornflour is naturally gluten-free. For individuals with celiac disease or gluten sensitivities, this makes it an excellent thickening agent for sauces, gravies, and soups, and a useful ingredient in gluten-free baking. The potential issue arises not from the corn itself, but from the facility where it is processed.
The Critical Role of Manufacturing Environments
The risk of cross-contamination is a major concern for those who must strictly avoid gluten. Many manufacturers produce a wide variety of goods, including those made with wheat, barley, or rye, in the same facilities. Without stringent protocols, airborne particles of gluten-containing flours can easily contaminate a naturally gluten-free product like cornflour. This is why certified gluten-free products are so important; they guarantee a safe manufacturing environment.
Aldi's Product Policy and the LiveGfree Line
Aldi acknowledges the need for clear dietary information and has established policies to help customers with special dietary needs. The most reliable gluten-free option at Aldi is their exclusive liveGfree brand. Products under this line are certified by independent organizations, such as the Gluten-Free Certification Organization (GFCO) or the Celiac Sprue Association (CSA), and are verified to contain less than 10 parts per million of gluten, which is a stricter standard than the FDA's requirement of less than 20 ppm.
Checking Aldi's Regular Cornflour
When it comes to Aldi's standard, non-liveGfree products, the gluten-free status is not as straightforward. Their general cornflour product, which may be sold under a house brand like 'White Mill' in some regions, should be checked carefully every single time you purchase it.
Key Steps for Verification:
- Read the Label: The product label is the single most important source of information. Always check the ingredient list for any potential gluten-containing additives or wheat-based products. Look for a clear 'Gluten-Free' claim or symbol.
- Search for Certification: If the packaging features a third-party gluten-free certification logo (like GFCO), you can be confident in its safety. Products in the liveGfree line will always have this.
- Check the 'May Contain' Warning: Be cautious of any 'May Contain' warnings related to wheat. While Aldi has strict allergen control, this warning indicates a risk of cross-contact at the manufacturing level. For individuals with celiac disease, this risk is often too high.
- Use the Aldi Website: The Aldi website provides product information, but it explicitly states that the online information may sometimes differ from the product in your local store due to regional variations or product updates. Always verify in person.
- Scan with Apps: Organizations like Coeliac UK offer apps or product lists that can help verify products.

Conclusion: Making a Safe Choice
While corn is a naturally gluten-free ingredient, you cannot assume that any cornflour is automatically safe for a celiac or gluten-sensitive diet. The safest approach is always to check the product's packaging for a certified gluten-free seal. For Aldi shoppers, this means either purchasing a product from their dedicated liveGfree line when available or meticulously examining the label of their regular house-brand cornflour for any 'gluten-free' claims and 'may contain' warnings. Given the constant potential for ingredient or processing changes, a cautious shopper will always perform this check with each and every purchase to ensure their health and safety.
