Gluten-free diets have become increasingly popular in recent years, with more and more people eliminating gluten from their diets due to celiac disease, gluten sensitivity, or simply as a lifestyle choice. For those following a gluten-free diet, it’s important to pay close attention to ingredient labels and avoid any products containing wheat, barley, rye, and other gluten-containing grains.
One pantry staple that often comes into question is corn oil. Mazola corn oil, in particular, is a popular brand of corn oil found in many kitchens. But is Mazola corn oil gluten-free? Let’s take a closer look.
What is Mazola Corn Oil?
Mazola corn oil is a type of vegetable oil made from corn. It is produced by ACH Food Companies and is one of the major brands of corn oil sold in the United States. Some key facts about Mazola corn oil:
– Made from the germ of corn kernels
– Extraction process involves pressing and/or chemical extraction using hexane solvent
– Versatile oil used for cooking, baking, salads, etc.
– Comes in both original and light varieties
– Has a high smoke point making it good for high-heat cooking/frying
– Neutral flavor allows it to be used in a variety of dishes without altering taste
Mazola has been around since 1911 and advertises its corn oil as 100% pure and natural. But when it comes to gluten, the big question remains – is it gluten-free?
What is Gluten?
Before discussing whether Mazola corn oil contains gluten, it’s important to understand what exactly gluten is.
Gluten is a general name for the proteins found in wheat, barley, rye, and other related grains. The two main proteins that make up gluten are:
– Gliadin
– Glutenin
When flour and water are combined and kneaded to make dough, these two proteins bond together and form elastic strands that give bread and other baked goods their chewy texture. Gluten helps dough rise and keep its shape. It also gives bread its spongy, fluffy crumb.
People with celiac disease or non-celiac gluten sensitivity cannot tolerate gluten and experience symptoms like abdominal pain, bloating, diarrhea, constipation, vomiting, fatigue, and more when they eat gluten-containing foods. Gluten can damage the small intestine in those with celiac disease.
Gluten in Vegetable Oils
Pure oils that are naturally gluten-free, like corn oil, olive oil, soybean oil, etc., do not inherently contain gluten proteins. However, gluten cross-contamination can sometimes occur:
– During growing and harvesting – Gluten grains may be grown near corn fields and get mixed in
– During processing – Shared equipment at facilities that process multiple grains
– During transportation and storage – Gluten and gluten-free grains stored together
Reputable oil manufacturers have protocols in place to prevent cross-contamination from occurring. But trace amounts of gluten can still find their way into oils if proper precautions are not followed.
Is Mazola Corn Oil Gluten-Free?
The good news is that Mazola corn oil is considered gluten-free.
Here are reasons why Mazola corn oil is free of gluten ingredients:
– Made 100% from corn – Corn does not naturally contain gluten.
– No gluten-containing ingredients are added – Mazola corn oil consists of purely extracted and refined corn oil.
– Produced in a dedicated facility – ACH Foods has designated facilities just for corn oil production.
– Stringent quality control measures – Mazola enforces high standards to avoid cross-contact with gluten.
The Mazola website clearly states that their corn oil is gluten-free. You can also contact their consumer affairs department for verification. Other major corn oil brands like Crisco are also considered gluten-free for similar reasons.
So people with celiac disease and gluten intolerance can comfortably use Mazola corn oil without worrying about gluten exposure. Those with extreme sensitivity should still check for latest gluten-free certification to be extra cautious. But Mazola corn oil is generally regarded as safe for gluten-free diets.
Using Mazola Corn Oil on a Gluten-Free Diet
Here are some tips for integrating Mazola corn oil into a gluten-free lifestyle:
– Use it for sautéing, stir-frying, grilling – Great for cooking nearly any meat, vegetable, gluten-free grains like rice and quinoa, etc.
– Incorporate into dressings and marinades – Whisk together oil, vinegar, mustard, herbs and spices for flavorful marinades or dressings free of gluten.
– Bake gluten-free goods – Mazola oil can be used to grease pans, oil cake tins, etc. when baking gluten-free recipes.
– Use in place of butter – Adds moisture to gluten-free baked goods and helps promote even browning.
– Make flavorful spreads – Blend oil with garlic, herbs and spices to create quick bread dips, sandwich spreads or veggie dips.
– Add to smoothies – For extra calories and healthy fats, drizzle or blend a bit of corn oil into your favorite smoothie recipe.
– Pop popcorn – A favorite gluten-free whole grain snack when popped in Mazola oil on the stovetop or in an air popper.
So Mazola corn oil is a versatile ingredient to always have stocked in your gluten-free kitchen. Just be sure to check the label and confirm the oil is marked gluten-free before purchasing and using.
Is Mazola Corn Oil Safe for Celiacs?
For those with celiac disease, it’s especially important to ensure the foods you eat are 100% gluten-free and free of cross-contamination. The good news is that Mazola corn oil is considered safe for people with celiac disease, though it’s not certified gluten-free.
Here’s why Mazola oil is generally safe for celiacs:
– Made from gluten-free corn, not grains containing gluten
– No gluten ingredients added during processing
– Manufactured in dedicated facilities away from gluten
– Gluten protocols followed to avoid cross-contact
– No gluten should be detectable through testing
– Well-tolerated by most people with celiac per consumer reviews
That being said, those with celiac disease are highly sensitive, so there is no guarantee the oil is 100% gluten-free. If you have celiac disease, it’s best to take these extra precautions:
– Contact manufacturer to ask about testing for gluten
– Look for lot numbers or bottling dates on the oil and call to check if the specific lot underwent gluten testing
– Purchase oils that are certified gluten-free by GFCO or another certifier
– Check for any signs of gluten grains in the oil before using
– Start with small amounts of the oil to see if you react before using it regularly
Being extra careful will help ensure the Mazola corn oil you use is safe for your celiac needs. But overall, Mazola oil is a good gluten-free option with proper precautions.
Mazola Oil Labels and Gluten Information
Reading the ingredient label of a food product is always the best way to check for gluten. Here is what you’ll find on Mazola Corn Oil labels:
Ingredients: Corn oil
As you can see, the ingredient list contains just one item – corn oil. No gluten-containing ingredients are present.
You’ll also find the following statement on Mazola Corn Oil:
“Part of a gluten free diet”
This lets consumers know the oil is suitable for gluten-free diets. But Mazola corn oil is not certified gluten-free, so celiacs should still take extra care and check for latest gluten testing results.
Some people also report seeing “May contain traces of gluten” on Mazola bottles. This is likely added for extra legal protection in case traces occur during transportation or handling. But many celiacs still use and tolerate Mazola corn oil just fine.
Check your specific bottle of Mazola Corn Oil for any gluten statements to be sure. But the ingredients and manufacturing process confirm the oil is intended to be gluten-free.
Alternative Oils for Gluten-Free Diets
In addition to Mazola brand, there are other corn oil options suitable for gluten-free diets, including:
– Store brand corn oils – Ingredients should just list corn oil
– Crisco Corn Oil – Also states gluten-free on label
– LouAna Oils – Offers organic, non-GMO corn oils
Oils made from other gluten-free grains are also fine for gluten-free diets:
– Rice bran oil
– Safflower oil
– Sunflower oil
– Grapeseed oil
– Peanut oil
– Avocado oil
For celiacs and others highly sensitive, looking for certified gluten-free oils is the safest option. Some certified oils include:
– Nutiva Organic Refined Coconut Oil
– Spectrum Naturals Organic Coconut Oil
– Chosen Foods 100% Avocado Oil
Checking for a certification logo from GFCO, the Celiac Support Association, or other trusted programs helps remove any doubt about gluten-free status.
Risk of Cross-Contamination
While the Mazola corn oil itself is gluten-free, there’s always potential for cross-contamination through:
– Shared equipment – Used to process other grains
– Shared storage/transport – With gluten-containing crops
– Shared fryers – Corn dogs, breaded foods, etc.
To avoid cross-contact, purchase oils from suppliers using good manufacturing practices and dedicated equipment. When cooking at home, keep oil separated from gluten-containing foods. Avoid using oil to fry breaded items.
Celiacs extremely sensitive to trace gluten should consider:
– Purchasing certified gluten-free oils
– Storing oil in a dedicated area sealed container
– Using a dedicated fryer or pan just for gluten-free cooking
Being vigilant protects the purity of your gluten-free oils and foods.
Corn Oil Refining and Gluten
There’s also the question of whether the refining process introduces any gluten into the finished oil. Here’s an overview:
– Extraction – Oil is extracted from corn germ using pressing and/or hexane solvents. No gluten exposure occurs.
– Degumming – Hydratable phospholipids are removed from oil. No gluten risk.
– Refining – Free fatty acids, color pigments and other impurities are removed using alkali chemicals followed by bleaching. Does not add gluten.
– Deodorization – Final step exposing oil to extremely high heat to remove odors and flavors. Gluten-free.
While refining steps may introduce other compounds, they do not add any gluten protein to the final liquid oil. The result is pure corn oil free of gluten-containing ingredients.
Does Heating or Frying Add Gluten?
Does simply heating or frying corn oil create any gluten? No – heating and frying do not cause corn oil to generate or produce gluten in any way.
Gluten comes from protein in wheat, barley and rye grains. Heating pure corn oil to any temperature cannot spontaneously produce gluten protein.
The only potential concerns are:
– Cross-contact from cooking breaded or gluten-containing foods in the same oil. Best to keep oils separate.
– Added seasonings that contain gluten, like flour-coated foods or batter mixes. Always avoid using gluten-based coatings.
So rest assured that no matter how hot you heat Mazola corn oil, the oil itself will remain 100% gluten-free. Just avoid cross-contact to keep foods gluten-free.
Is Mazola Corn Oil Distilled?
No, Mazola corn oil is not distilled. Here is how it is processed:
1. Corn germ is pressed to extract crude corn oil
2. Crude oil undergoes solvent extraction using hexane
3. Oil is refined using degumming, alkali refining, bleaching and deodorization
4. Citric acid may be added as a preservative
Mazola oil does not undergo any type of distillation process. Distillation is more commonly used to purify alcohol and certain types of oils like essential oils.
So while extensive refining removes impurities from Mazola corn oil, the oil itself is not distilled during production. It retains its natural corn oil composition without the need for distillation.
Testing Mazola Oil for Gluten
While Mazola follows practices to avoid gluten cross-contact, the oil is not certified gluten-free. For assurance, you can contact the manufacturer to ask:
– Do you perform gluten testing on the corn oil? What is the testing process?
– What are the typical testing results for gluten levels?
– Are entire manufacturing runs tested or just periodic spot checks?
– Can you provide testing results for the lot code on my specific bottle?
Testing each batch would provide the most definitive proof of gluten-free status. But even periodic testing offers some helpful validation.
You can also send a bottle of the oil to an independent lab yourself to test for gluten. Look for labs that use validated testing methods able to detect gluten down to at least 10-20 parts per million.
While not always necessary, third-party testing may provide added peace of mind for celiacs and those highly sensitive.

Should I Trust Corn Oil in Restaurants/Cafeterias?
Dining out with celiac disease or a gluten allergy requires extra diligence since you rely on food prep by others. Here are some tips for corn oil safety when eating out:
– Ask how they store, handle and use corn oil. Look for dedicated fryers.
– Request to see the brand of oil they use and check labels/ingredients if possible.
– Avoid breaded, battered fried menu items that likely share fryers.
– Verify oil is changed frequently to avoid gluten buildup from fried foods.
– Check that utensils and vessels that contain oil are washed well between uses.
– Ask if gluten-free menu items are prepared separately from gluten foods.
– Inform staff of your needs for absolute avoidance of cross-contact.
– Choose naturally gluten-free foods like grilled/roasted meat and vegetables.
– Check reviews to see if other celiacs have safely eaten there.
Diligence is required since many restaurants still lack sufficient knowledge and training on gluten-free needs. Letting them know the importance of safe gluten-free preparation helps increase awareness.
Is Corn Oil Safe on a Wheat-Free Diet?
Yes, corn oil is perfectly safe for people who need to avoid wheat. Pure corn oil contains no wheat ingredients whatsoever.
The only potential concern is cross-contamination. Wheat could potentially get mixed in with corn crops during planting, harvesting, transport or processing.
But reputable brands like Mazola ensure the entire supply chain is wheat-free through good manufacturing practices. So corn oil itself is 100% wheat-free.
Just be mindful when cooking at home – avoid reuse of oil that’s been used to fry wheat-containing foods like breaded items. And check restaurant oil handling carefully.
As long as you verify proper procedures, corn oil is an ideal ingredient for wheat avoidance diets. The oil provides a versatile way to cook and add great flavor to wheat-free meals.
