How Cheetos Are Made: From Cornmeal to Cheesy Crunch

Cheetos—those bright orange, irresistibly cheesy snacks—have been a beloved treat since their introduction in 1948 by Frito-Lay . While the process of making them might seem like a mystery, it’s actually a fascinating combination of industrial engineering, precise cooking techniques, and rigorous quality control. Here’s a step-by-step look at how these iconic snacks are manufactured. The Main Ingredients Cheetos start with a simple foundation: corn. The primary raw material is corn grits (or cornmeal), typically ground to 20-mesh size . Water is added to create a dough-like mixture. The corn’s germ is removed during processing to prevent spoilage, which means the cornmeal lacks certain nutrients—so manufacturers use enriched cornmeal to […]

How to Properly Clean a Food Extruder (Puffing Machine)

Food extruders—commonly used to produce puffed snacks, breakfast cereals, and textured proteins—require thorough and regular cleaning to ensure product quality, food safety, and equipment longevity.
