Wheat and Flour Production
Wheat and Flour Production: The Journey from Grain to Flour
Flour, a ubiquitous ingredient in countless culinary creations, traces its origins back to the humble wheat grain. Wheat, belonging to the grass family, is the primary source of flour worldwide, renowned for its versatility and nutritional value.
The journey from wheat to flour is a complex yet fascinating process involving several intricate steps. Farmers carefully cultivate wheat crops, nurturing these grains to maturity. Once harvested, the wheat undergoes a meticulous transformation at flour mills.
Milling: Breaking Down the Grain
The milling process begins with the separation of wheat kernels from the surrounding chaff. State-of-the-art machinery gently grinds the kernels, reducing them to coarse particles known as semolina. This semolina is then subjected to further grinding, resulting in a finer powder—the flour we know and love.
