Cereal flours consist either of the endosperm, germ, and bran milled together (resulting in whole-grain flour) or of the endosperm alone (refined flour).
Universal White Wheat Flour - this flour is made by grinding only the endosperm of the wheat grain.
The color is white and it is mostly used to make bread or anything that requires flour in composition (universal use, all-purpose flour).
The universal white wheat flour has a high gluten content.
