Is Maltodextrin Gluten-Free?
Maltodextrin is gluten-free — even when made from wheat. It is so highly processed that the gluten protein is removed, and celiac organizations consider it safe.

Maltodextrin sounds alarming because of the word "malt," but it is unrelated to barley malt. It is a highly processed starch usually made from corn, rice, or potato — and even when it is made from wheat, the processing removes the gluten protein to well below the 20 ppm threshold the FDA requires for gluten-free labeling (21 CFR 101.91).
In the US, if maltodextrin is derived from wheat, the word "wheat" must appear on the label under FALCPA allergen rules — but the Celiac Disease Foundation still classifies maltodextrin as gluten-free regardless of source. In the EU, wheat-based maltodextrin is explicitly exempt from allergen labeling because it is considered safe for celiacs.
The confusion with barley malt is the real risk: "malt extract," "malt flavoring," and "malt syrup" ARE made from barley and are NOT gluten-free. Maltodextrin is a different ingredient entirely.
How to check the label
- Do not confuse maltodextrin with "malt extract" or "malt flavoring" — those are barley-based and unsafe
- In the US, wheat-derived maltodextrin will say "wheat" on the label — it is still considered gluten-free, but the most sensitive celiacs may prefer corn-based versions
- In products labeled "gluten-free," maltodextrin is always from a safe source or processed below 20 ppm
