Sugar is flammable, especially as a fine dust, which can ignite and cause dangerous explosions.
In 2008, there was a Imperial Sugar refinery disaster on 7 February 2008, where fourteen people were killed and thirty-six injured during a dust explosion at a refinery owned by Imperial Sugar in Port Wentworth, Georgia, United States.
Sugar burns like alcohol when it's heated, and caramelizes when cooked and powdered sugar dispersed in the air creates flammable clouds, which makes sugar a significant combustible dust hazard that requires strict safety measures.
Other foods and ingredients that are flammable are marshmallows and Fritos and other chips as well as bacon and alcohol based sauces or spirits.
Flour, sugar, cocoa and spices are also flammable as well.
Fritos are also highly flammable because the corn oil that Fritos are fried in, act like a greasy candle which can be used as a makeshift fire starter and burn for a surprising amount of time once the Fritos are lit, which is similar other chips that are rich in oil.
Fritos are saturated with oil, which is a fuel source for fire, and makes the Fritos ignite easily and burn steadily, especially for the original unseasoned versions.
And the compact corn based structure of Fritos chips provides a solid base for the oil to sustain a fire.
Potato chips are flammable due to their high fat and high oil content, which makes the potato chips excellent fire starters, which is similar to kindling.
The potato chips need an open flame to ignite, but the carbohydrates and fats burn readily and some chips can even reach high temperatures and burn hotter and longer than most would expect them to burn.
Both Dorito dust and the Dorito chips themselves are also very flammable because Doritos are made with corn and oil, which are also hydrocarbons and starches, which make them great for starting fires with, especially when the Doritos are crushed into fine dust which increases the surface area for oxygen to fuel the combustion.
Doritos and Dorito dust work like a wick in an oil lamp, with the oil vaporizing and igniting easily and allows them to burn vigorously and support a flame.
Doritos and Dorito dust can easily be lit on fire as a result on fire as a result of their composition of corn starch vegetable oil, like hydrocarbons and flavorings, which makes the Doritos and Dorito dust excellent fire starters.
Doritos and Dorito dust can also sustain flames long enough to ignite kindling, which is similar to a fire starter log.
And the high oil content and large surface area of the Doritos from the ground corn create a combustible, energy rich fuel source which burns readily and hot.
Even Cheetos and many other chips can be flammable and catch on fire as well as they are fatty foods and contain hydrocarbons which both burn readily.
