What does corn flour contain?

Corn flour primarily contains carbohydrates in the form of starch, which makes up about 85% of its composition. The starch in corn flour is responsible for its thickening properties and is used as a thickening agent in various food applications.

In addition to carbohydrates, corn flour also contains:

1. Protein: Corn flour contains a moderate amount of protein, around 10-12%. The protein in corn flour is primarily composed of zein, which is a type of prolamin.

2. Fiber: Corn flour contains a small amount of dietary fiber, around 2-3%. The fiber in corn flour is insoluble, meaning that it does not dissolve in water and can help promote digestive health.

3. Vitamins and Minerals: Corn flour contains various vitamins and minerals, including iron, zinc, magnesium, phosphorus, and B vitamins such as niacin and thiamin. However, the levels of these nutrients in corn flour can vary depending on the type of corn used and the processing methods.

It's important to note that corn flour made from whole cornmeal will retain more of the nutrients compared to corn flour made from refined cornmeal. Additionally, the nutritional profile of corn flour can be affected by factors such as the specific variety of corn used and the processing conditions.
