Corn flour, a staple in kitchens worldwide, has sparked curiosity and concern regarding its processing. While some believe it’s a natural product, others question the extent to which it has been altered. This blog post aims to shed light on the topic of “is corn flour processed” by exploring its journey from corn kernels to the flour we use.
The Journey of Corn Flour
The production of corn flour involves several steps:
1. Harvesting and Drying: Corn kernels are harvested and dried to remove moisture.
2. Milling: The dried kernels are coarsely ground to create cornmeal.
3. Sifting: To separate the coarse bran from the fine flour, the cornmeal is sifted.
4. Germ Removal: The corn germ, the oily part of the kernel, is removed to extend the flour’s shelf life.
5. Grinding and Sifting: The remaining endosperm is further ground and sifted to obtain fine corn flour.
