Distilled Vinegar: The distilled vinegar used in the mustard is safe for those with celiac disease, as the distillation process removes gluten proteins.

Confirming the Gluten-Free Status of Kroger Yellow Mustard

Individuals with celiac disease or a gluten sensitivity must read ingredient labels when grocery shopping. Kroger's standard yellow mustard is gluten-free. The manufacturer states that the product is gluten-free. This makes it a safe option for adding flavor to hot dogs, sandwiches, and other dishes. The ingredient list contains no gluten-containing grains like wheat, barley, or rye.

Decoding the Ingredient List

The ingredients help to understand why Kroger brand yellow mustard is gluten-free. The components are naturally gluten-free.

Vinegar: This can be a point of confusion for some, as vinegar can be made from various sources, including grains. However, the distillation process used for most commercial vinegars, including those in Kroger's mustard, effectively removes the gluten protein. Therefore, distilled vinegar is widely considered safe for those with celiac disease.
Water: A basic, gluten-free component.
Mustard Seed: Mustard seeds are naturally gluten-free and are the core ingredient for all mustard products.
Salt: A mineral and a common seasoning that is gluten-free.
Turmeric: A spice derived from a root, turmeric is naturally gluten-free.
Paprika: A spice made from dried peppers, paprika is also naturally gluten-free.

The simple nature of this ingredient list is reassuring for those on a strict gluten-free diet. The manufacturer also notes that the product is free from cereals and their derivatives.

Navigating Varieties and Cross-Contamination Risks

While standard yellow mustard is a safe bet, always exercise caution with other condiments and different mustard types. Cross-contamination can occur in manufacturing facilities, and some specialty mustards may contain hidden sources of gluten.

Potential Gluten Sources in Condiments

Thickeners: Some cheaper or specialty mustards might use wheat flour or starch as a thickener.
Malt Vinegar: Malt vinegar is derived from barley and is not gluten-free. It's a common ingredient in English mustards and some vinaigrettes.
Soy Sauce: Many condiments, marinades, and sauces contain soy sauce, which is typically made with wheat. Unless specifically labeled gluten-free (e.g., Tamari) it should be avoided.
Spice Blends: Pre-packaged spice mixes can sometimes contain anti-caking agents or other additives with gluten.
Shared Equipment: For individuals with celiac disease, products made on shared equipment with gluten-containing items pose a risk. Kroger offers their Simple Truth Organic® Yellow Mustard which is explicitly labeled organic, non-GMO, and free from over 101+ unwanted ingredients, including gluten.
