TAHIL VE PSEUDO-TAHILLARIN ISLAK ÖĞÜTME TEKNOLOJİSİ.

The purpose of the milling is to separate the main fractions of the grain due to milling method and is to use them for food or other industries. The milling can be classified as dry and wet milling. The purpose of the wet milling is to separate the main chemical constituents of the grain, such as starch, protein, dietary fibre and crude oil; the purpose of the dry milling is to separate the endosperm, germ and bran parts of the grain. All constituents can be separated with the highest purity in the wet milling; on the contrary the principle of the dry milling is to obtain the refine or wholegrain flour with the highest quality. The wet milling, which is an industrial process, separates the essential fractions of cereal or pseudo-cereals using physical, chemical, biochemical and mechanical processes. The wet milling starts with steeping process, and then the grain constituents are separated with mechanic splitting. The wet milling process is mostly applied to wheat and corn, besides it is also employed for some cereals like sorghum, barley, oat and rice. The wet milling of pseudo-cereals such as buckwheat, quinoa and amaranth is still carried out in a laboratory scale. The wet milling conditions of cereal/pseudo-cereals completely affect the starch yield and its physicochemical properties. [ABSTRACT FROM AUTHOR]
