From Cheetos to Doritos, America runs on snacks that are made with powdered ingredients. One of the country’s most popular snack brands, Funyuns, stands out because of its savory onion flavor. National Geographic’s Ultimate Factories series recorded this footage of a Funyuns production line at a Frito-Lay plant to show some of the processes and technologies used to manufacture the product.

The narrator explains that the production process starts with mixing corn meal with water. After the mixture is transported into a hopper, the moist corn meal is extruded through a dye into an onion ring shape.

A visualization of the extruder walks viewers through the process of kneading and heating the dough and forming it into the products signature shape. Once formed, the rings are fried and then coated with powdered flavoring in a drum.

Frito-Lay celebrated the 50th anniversary of the Funyuns brand in 2019.
