2022年11月12日 · Funyuns have been sold in the US since 1969. George Wade Bigner, who worked for Frito-Lay in the 60s, invented the snack. Funyuns are made of cornmeal that is shaped into rings through an extrusion process. This leads to a product that has a fried food-type texture, and it also makes it possible for Funyuns to have an onion ring shape.
