Vanilla pods do not contain gluten, but products advertised as vanilla may not be gluten-free. Pure vanilla extract must follow FDA guidelines and cannot contain gluten. Vanilla ice cream may not be gluten-free due to possible contamination. Powdered forms of vanilla may contain harmful proteins. Whole vanilla beans are a safe option for gluten-free recipes.
There is no gluten in vanilla pods. That doesn’t mean products advertised as vanilla are gluten-free. The vanilla bean itself, however, does not contain the proteins that can be harmful to celiacs.
One of the most used forms of vanilla is vanilla extract. The US Food and Drug Administration (FDA) has set strict guidelines on what can be called pure vanilla extract. These rules state that “pure” extract can only contain a small amount of ingredients other than vanilla, and none of those ingredients contain gluten.
Part of the confusion about gluten in vanilla extract stems from the idea that the alcohol used to help extract the flavor from the vanilla beans might have been distilled from the gluten-containing grains. Even if it is, the alcohol used in pure vanilla extract must be distilled according to FDA guidelines. The distillation process involves the transformation of liquids into gas and the subsequent cooling of the gas into liquid. Proteins dangerous for celiacs cannot be transformed into a gaseous form and are removed from alcohol through the distillation process. This means that whatever type of distilled alcohol is used in pure vanilla extract, it will not contain gluten.
Another product that contains vanilla is ice cream. There is no gluten in vanilla ice cream, but there may be other components that may contain gluten. Depending on the facility where the ice cream was made, it is possible that contamination from gluten-containing ingredients used in other products or flavors could leach into the ice cream. Even vanilla ice cream that has added flavors may not be gluten-free, especially if the added ingredients come from a separate manufacturer. There are brands of ice cream available, however, that clearly state they are gluten-free.
The gluten in vanilla can be found in powdered forms used in high-volume cooking and for industrial production. The process and ingredients added to make the final product could contain harmful proteins. This can be especially problematic for people with celiac disease, because not all cuisines are aware of the gluten content of the powder, making their dishes potentially unsafe.
For those still in doubt, the best practice may be to purchase whole vanilla beans. Having absolutely no potential to find gluten in vanilla beans, they could be used in gluten-free recipes. There are also ways a vanilla extract can be made at home using water or neutral distilled alcohols.
