Grain milling is a process that separates the bran, endosperm, and germ of a grain kernel. The bran is the outer layer of the kernel, the endosperm is the starchy inner portion, and the germ is the small, oily core of the kernel.

Hammer mills are not used for grain milling. They are typically used for grinding materials such as wood, plastic, and metal.

Bolting is the process of separating the bran from the endosperm and germ. It is done by passing the milled grain through a series of screens with different sized holes.

Tempering grain before milling increases the moisture content of the grain, which makes it more pliable and easier to mill.

Grits are not a type of grain product. They are a type of cornmeal that is made from coarsely ground corn kernels.

Starch is the primary component of wheat flour. It is a complex carbohydrate that provides energy to the body.

Semolina flour is not a type of wheat flour. It is a type of durum wheat flour that is used to make pasta and couscous.

Bread flour has a higher protein content than all-purpose flour. This makes it ideal for making bread, as the higher protein content helps to create a strong gluten network, which results in a chewy, elastic loaf of bread.

Starch is the primary component of rice. It is a complex carbohydrate that provides energy to the body.

Wild rice is not a true rice. It is a type of aquatic grass that is native to North America.

Brown rice is made from whole grain rice, which means that it contains all of the bran, germ, and endosperm of the rice kernel. White rice is made from refined rice, which has been milled to remove the bran and germ, leaving only the endosperm.

Starch is the primary component of corn. It is a complex carbohydrate that provides energy to the body.

Popcorn is not a type of corn product. It is a type of corn kernel that pops when heated.

Cornmeal is a finer grind than cornstarch. Cornmeal is made from coarsely ground corn kernels, while cornstarch is made from finely ground corn kernels.

Starch is the primary component of barley. It is a complex carbohydrate that provides energy to the body.

Barley water is not a type of barley product. It is a beverage made from boiling barley in water.
