The heavier starch slurry is then washed multiple times in hydrocyclones with fresh water. The starch stream typically has 90% starch and the gluten stream consists of 60% protein. [ 4 ] The lighter gluten, separated out from the top, is thickened and the heavy gluten is further sent for dewatering into vacuum rotary filter.
Coarsely ground corn flour (meal) is known as cornmeal. [ 3 ] [ 4 ] When maize flour is made from maize that has been soaked in an alkaline solution, e.g., limewater (a process known as nixtamalization ), it is called masa harina (or masa flour), which is used for making tamales and tortillas .

Corn starch mixed in water. Cornflour, cornstarch, maize starch, or corn starch (American English) is the starch derived from corn grain. [2] The starch is obtained from the endosperm of the kernel. Corn starch is a common food ingredient, often used to thicken sauces or soups, and to make corn syrup and other sugars. [3]
Starch production is an isolation of starch from plant sources. It takes place in starch plants. Starch industry is a part of food processing which is using starch as a starting material for production of starch derivatives, hydrolysates, dextrins. [1] At first, the raw material for the preparation of the starch was wheat.
Cornmeal is a meal (coarse flour) ground from dried maize. It is a common staple food and is ground to coarse, medium, and fine consistencies, but it is not as fine as wheat flour can be. [ 1 ] [ 2 ] [ 3 ] In Mexico and Louisiana, very finely ground cornmeal is referred to as corn flour .
The endosperm goes through screenings to separate starch and proteins from the corn fiber or bran. The remaining starch and proteins are centrifuged to separate the starch from the corn gluten meal. [2] Corn gluten meal as commonly produced contains "71.4% crude protein, 4.1% fat, 0.8% fiber, 1.2% ash, 12.4% starch, 10.1% other carbohydrates".
Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Sweet corn is picked when still immature (the milk stage) and prepared and eaten as a vegetable , unlike field corn , which is harvested when the kernels are dry and mature (dent ...
The kernel is used as oil, bran, starch, glutamates, animal feed, and solvents. The silk is combined with other parts of the corn plant to be used as part of animal feed, silage, and fuels. Husks are made into dolls and used as filling materials. The stalk is used to make paper, wallboard, silage, syrup, and rayon (artificial silk)." [1]
