Are Doritos Flammable? Myth or Reality?

Doritos are a popular American snack food that has been around since the 1960s. They are a type of corn chip that is known for its bold and unique flavor.

However, there has been a lot of talk about whether or not Doritos are flammable.

So, are Doritos flammable? The answer is yes. Doritos are made with corn starch, which is a carbohydrate that is highly flammable.

Additionally, they are coated in vegetable oil, which also makes them more flammable. While they won’t ignite at low temperatures, once they catch fire, they can sustain a flame for a while.

Many people have been curious about why Doritos are flammable and whether or not they are safe to eat.

In this article, we will explore the science behind why Doritos burn and whether or not they pose a risk to consumers.

What Are Doritos?

Doritos are a popular brand of tortilla chips that come in a variety of flavors.

They were first introduced in 1964 and have since become some of the most in-demand chips in the world.

Doritos are made from corn, which is ground into a fine powder called cornmeal. The cornmeal is then mixed with water and other ingredients to form a dough.

The dough is then pressed into thin sheets and cut into triangular shapes. The chips are then fried in oil until they are crispy and golden brown.

After frying, the chips are seasoned with various flavors, such as cheese, chili, salt, and cool ranch.

Doritos are widely available in grocery stores and convenience stores around the world. They are often consumed as a snack on their own or used as a topping for nachos and other dishes.

What is Flammability?

Flammability is the ability of a substance to ignite and burn when exposed to heat, flame, or spark.

It is a property of materials that determines how easily they can catch fire and how quickly they can spread flames.

Flammable substances are those that can ignite and burn easily, while non-flammable substances do not burn or support combustion.

The flammability of a substance depends on several factors, such as its chemical composition, physical state, and environmental conditions.

Some common flammable substances include gasoline, alcohol, propane, and wood.

These materials have low flash points, which means they can ignite at relatively low temperatures.

Other substances, like water and sand, are non-flammable and can be used to extinguish fires.

Experiment: Setting Doritos on Fire

It is not recommended to try this experiment at home, but firefighters and scientists have conducted experiments to test the flammability of Doritos.

When exposed to a flame, Doritos chips can catch fire and burn quite easily. The chips can sustain a flame for a while, depending on the amount of oil coating the chips.

One experiment involved lighting a single Dorito chip on fire and timing how long it burned.

The chip burned for approximately 50 seconds before extinguishing on its own.

Why Doritos are Flammable?

The primary reason Doritos are flammable is due to their carbohydrate content. The chips are made with corn starch, which is a carbohydrate that burns well for fuel.

When ground into a fine powder like cornstarch, the extra surface area makes it even more flammable.

In addition to corn starch, Doritos are coated in vegetable oil during the cooking process. This oil is another ingredient that causes the chips to be highly flammable.

When exposed to a flame, the oil can ignite and cause the chips to burn quickly.

Safety Concerns

While it may be tempting to try setting Doritos on fire, it is important to remember that doing so can be dangerous.

The flames can quickly get out of control and cause a fire. Additionally, inhaling the smoke from burning Doritos can be harmful to one’s health.

It is important to always use caution when handling fire and flammable materials. In the case of Doritos, it is best to enjoy them as a snack and not as a fire starter.

What to Do if Doritos Catch Fire?

It is important to remember that Doritos are flammable and can catch fire easily. If this happens, here are some steps to follow:

  • Turn off the heat source immediately if the fire is on a stove or oven.
  • Do not attempt to extinguish the fire with water, as this will only spread the flames.
  • Use a fire extinguisher or a fire blanket to smother the flames.
  • If you do not have a fire extinguisher or a fire blanket, use a lid to cover the burning Doritos and cut off the oxygen supply.

It is important never to attempt to put out a fire with your bare hands or to blow on the flames, as this can cause the fire to spread and cause serious injury.

If the fire is too large to handle, evacuate the area immediately and call the fire department. Do not attempt to put out the fire yourself.

Remember always to be cautious when handling flammable materials and to take the necessary precautions to prevent fires from occurring.


After researching the topic of whether or not Doritos are flammable, it is clear that they can be.

The combination of carbohydrates and vegetable oil in the chips makes them highly flammable, and they can burn easily once ignited.

It is important to note that while Doritos can be flammable, they should not be used as kindling or as a fire starter. Doing so can be dangerous and can lead to unintended fires.

It is also worth mentioning that Doritos are not the only snack that can be flammable.

Other snacks such as Cheetos, tortilla chips, and some Frito-Lay products can also be flammable due to their ingredients.

Overall, while it is interesting to know that Doritos can be flammable, it is important to use caution and not intentionally try to light them on fire. Enjoy them as a snack, but do so safely.

What happens when you light a Dorito on fire?

When you light a Dorito on fire, the snack will burn and produce flames.

This is because Doritos are made of cornmeal, vegetable oil, and seasonings, all of which are flammable.

Burning Doritos can produce harmful smoke and fumes, so it is not recommended to intentionally light them on fire.

What chips are the most flammable?

Snack chips like Doritos, Cheetos, and other common types are quite flammable due to their fatty and hydrocarbon content.

These chips are made with corn starch and are coated in vegetable oil, both of which are flammable.

Are potato chips flammable?

Yes, potato chips are flammable. Potato chips are made of potatoes, which are carbohydrate-based food, and are fried in oil, which is a flammable material.

When you light a potato chip on fire, it will burn and produce flames because of these flammable main ingredients.
