Semolina is then ground into flour. This greatly simplifies the process of separating the endosperm from the bran and germ, as well as making it possible to separate the endosperm into different grades because the inner part of the endosperm tends to break down into smaller pieces than the outer part. Different grades of flour can thus be produced. Semolina made from durum wheat is yellow in color. Semolina is often used as the base for dried products such as couscous, which is made by mixing roughly 2 parts semolina with 1 part durum flour (finely ground semolina). Broadly speaking, meal
Semolina terms for wheat, "samita" and "godhuma", or may be loan words from the Semitic root "smd" – to grind into groats ("cf." ""). Modern milling of wheat into flour is a process that employs grooved steel rollers. The rollers are adjusted so that the space between them is slightly narrower than the width of the wheat kernels. As the wheat is fed into the mill, the rollers flake off the bran and germ while the starch (or endosperm) is cracked into coarse pieces in the process. Through sifting, these endosperm particles, the semolina, are separated from the bran. The semolina
