What is commercial flour?

Commercial flour is a finely ground powder made from wheat or other grains, produced for widespread sale and use in baking and cooking. It is typically processed to remove the bran and germ, resulting in a longer shelf life and a finer texture. Various types of commercial flour exist, including all-purpose, bread, and cake flour, each formulated for specific culinary applications. The production process often involves bleaching and enriching to enhance the flour's properties and nutritional content.
