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
Dish structure used for the first time in 1967 by Stauffer and by Wentworth. Comprehensive studies are due to Lowe and LoPiccolo in 1974 and Lowe in 1975. The subhorizontal dish structure consists of two parts, the dish itself and the [sediment] contained within the dish plus the region stretching up to the bounding surface of the overlying dish(or dishes) above. The bounding surface of the dish can take on variable shapes, from substantially flat to bowl-like and to strongly concave up. The bounding surfaces are thin, (and usually) dark(er) laminae; they are richer in clay, silt or organic material than the
