If you pick up a bag of gluten-free pretzels, a packet of salad dressing, or even a bottle of artificial sweetener, you will almost certainly see maltodextrin on the ingredient list.
It sounds like "malt" (which comes from barley and is extremely unsafe). So, is maltodextrin safe for celiacs, or is it a hidden source of gluten?
The answer is: Usually yes, but you have to know where you are.
Here is the complete, no-nonsense guide to maltodextrin.
What is Maltodextrin?
Maltodextrin is a highly processed white powder used as a thickener, filler, or preservative in packaged foods. It has virtually no flavor and is very cheap to produce, which is why food manufacturers love it.
Despite the word "malt" in the name, maltodextrin is not made from barley malt.
Is Maltodextrin Gluten-Free?
In the United States and Canada: YES
In North America, maltodextrin is almost exclusively derived from corn, rice, or potatoes—all of which are naturally gluten-free.
If a US manufacturer uses wheat to make maltodextrin, the FDA’s strict allergen labeling laws require them to explicitly declare it on the label as "Maltodextrin (Wheat)" or include a "Contains: Wheat" statement at the bottom of the ingredient list.
Therefore, if you are in the US and see plain "maltodextrin" on a label with no wheat warning, it is safe to consume.
In Europe, the UK, and Australia: STILL YES (With a Catch)
In Europe and Australia, maltodextrin is frequently derived from wheat.
However, the processing methods used to create maltodextrin are so intense and highly refined that they completely remove the gluten protein. According to the European Food Safety Authority (EFSA) and Coeliac UK, wheat-derived maltodextrin is considered safe and gluten-free because the gluten levels are well below the 20 parts per million (ppm) threshold.
*(Note: If you have a true wheat allergy, as opposed to celiac disease, you may still need to avoid wheat-derived maltodextrin).*
The Real Danger: Cross-Contamination
The maltodextrin itself isn't the problem—the highly processed foods that contain it are.
Foods packed with maltodextrin (like cheap potato chips, instant gravy packets, and frozen dinners) are often manufactured in shared, high-risk facilities where cross-contamination with real wheat flour is rampant.
