Understanding Mayonnaise and Gluten
Mayonnaise is a popular condiment used in countless dishes, from sandwiches to potato salad. In its most basic, traditional form, mayonnaise is made from a simple emulsion of eggs, oil, and an acid like vinegar or lemon juice. Since these core ingredients are naturally free of gluten-containing grains (wheat, barley, rye), traditional mayonnaise is generally considered gluten-free and safe for individuals on a gluten-free diet.
However, commercial mayonnaise products, including light and fat-free versions, often contain additional ingredients to improve texture, stability, and shelf life. These additives, which can include modified food starch, certain spices, or malt vinegar, can be potential sources of hidden gluten, making careful label reading essential.
The Ingredients in Great Value Light Mayonnaise
To determine if Great Value light mayonnaise is gluten free, the first step is to examine its ingredient list. According to product information, the primary ingredients include water, soybean oil, and modified food starch (corn, potato). Other components are sugar, distilled vinegar, eggs, salt, and lemon juice concentrate.
- Modified Food Starch: The presence of
MODIFIED FOOD STARCH (CORN, POTATO)is a key indicator. While generic modified food starch could be wheat-derived, the label's explicit reference to corn and potato specifies a gluten-free source in this instance. However, this is where a distinction is crucial; generic versions require extra caution. - Distilled Vinegar: In the US, distilled vinegar is typically gluten-free, as the distillation process removes gluten proteins even if a gluten-containing grain was used. This is different from malt vinegar, which is not gluten-free.
- Other Ingredients: The remaining ingredients, such as soybean oil, eggs, and seasonings, do not contain gluten.
The Lack of Gluten-Free Certification
For those with celiac disease, relying solely on an ingredient list can be risky due to potential cross-contamination. For this reason, a third-party "Certified Gluten-Free" label is the safest indicator. Based on search results and product checks, Great Value light mayonnaise does not carry this certification.
Walmart's Great Value brand has, in the past, caused confusion for gluten-free consumers due to inconsistent labeling. While some Great Value products, like certain pastas and baking mixes, are indeed certified gluten-free, this certification does not apply to the light mayonnaise. The absence of an official certification means there is no third-party guarantee that the product contains less than 20 parts per million of gluten, the standard for a safe gluten-free food in the U.S..
The Risk of Cross-Contamination
For individuals with celiac disease, cross-contamination is a significant concern. The Great Value light mayonnaise is likely produced in a facility that also processes products containing wheat. While Walmart has indicated a policy of not labeling items as 'gluten-free' if made on shared lines, some past labeling issues have created uncertainty. Without specific third-party certification, there is no guarantee that the product is free from trace amounts of gluten that could trigger a reaction.
Cross-contamination can also occur at home, particularly if a shared jar of mayonnaise is used with utensils that have come into contact with gluten-containing foods like bread. For this reason, using squeeze bottles or dedicated, labeled jars for gluten-free condiments is a recommended practice for households with mixed diets.

How to Safely Choose Mayonnaise
If you follow a strict gluten-free diet, it is important to take proactive steps when choosing any commercial condiment.
- Look for the Label: Always check for a reputable "Certified Gluten-Free" label on the product packaging. This is the most reliable indicator of safety for those with celiac disease.
- Read All Ingredients: Scrutinize the full ingredient list, especially for unspecific terms like "modified food starch" or "natural flavors". If a brand does not explicitly state the source, contact the manufacturer to be sure.
- Be Mindful of Brand Policies: Be aware of a brand's general labeling practices. While Great Value has other certified products, their store-brand mayo does not seem to be one of them.
- Consider Making Your Own: For complete control and peace of mind, homemade mayonnaise is the safest option. It requires just a few naturally gluten-free ingredients.
- Avoid Shared Jars: In households with mixed diets, prevent cross-contact by using separate, clearly labeled jars of mayonnaise or using a squeeze bottle.
Conclusion: The Final Verdict on Great Value Light Mayonnaise
So, is Great Value light mayonnaise gluten free? The ingredients list does not contain any gluten-containing items, with the modified food starch being explicitly labeled as corn and potato. However, the product lacks third-party gluten-free certification, and there is a documented risk of cross-contamination during manufacturing within Walmart's supply chain. For individuals with celiac disease, this risk is unacceptable, and the product is not recommended. For those with less severe gluten sensitivities who can tolerate trace amounts, a careful review of the label might suffice, but a certified product remains the safest choice. When in doubt, always err on the side of caution and opt for a product with a clear, certified gluten-free label to ensure your health and safety.
