Why Do Cheetos Have Cheese Dust?

Most cheese dust, whether it’s found in packets of Kraft macaroni and cheese, on Cheetos or on Doritos, is made from the same thing: dehydrated processed cheddar cheese. Most cheesy snacks are made by spray-drying (blasting liquid cheese into a chamber with hot air). This makes the cheese evaporate, and a solid substance is left behind. Add some artificial neon orange coloring and you’ve got yourself some Cheetos dust.
