Economic importance of endosperms is that they form the base for cereals and pulses as well as oilseeds. Large amount of stored food in the endosperm of various plants allow their usage as foodcrop. The bran which is removed from the endosperm of the food crops during the refining process provides fibers and proteins from the aleurone layer. The germ is also removed during refining process and is a good source of vitamins, proteins and oils.
