the pigment strand, and together they form complete coat about the endosperm Structure and Composition of Cereal Grains 3 Fig. 1 Diagrammatic illustrations of wheat structure. (From Lasztity, 1.) and germ. Three layers can be distinguished in the seed coat: thick outer cuticle, color layer that contains pigment, and very thin inner cuticle. The bran comprises all outer structures of the kernel inward to, and including, the aleurone layer. This layer is the outerlayer of the endosperm, but is considered as part of the bran by millers. The aleuronelayer is usually one cell thick and almost completely surrounds the kernel over the starchyendosperm and germ. The endosperm is composed of peripheral, prismatic, and centralcells that are different in shape, size, and position within the kernel. The endosperm cells are packed with starch granules, which lie embedded in matrix that is largely protein. Additional details on the wheat structure can be found in Lasztity (. 2.1.2 CornCorn or maize ( Zea mays .) is an important cereal crop in North America. Maize within few weeks, develops from small seed to plant, typically 2- to 3.5- tall. Corn appar-ently originated in Mexico and spread northward to Canada and southward to Argentina. The corn seed is single fruit called the kernel. It includes an embryo, endosperm, aleu- rone, and pericarp. The pericarp is thin outer layer that has protection role for theendosperm and embryo. Pericarp thickness ranges from 2 to 1 among genotypes. Pericarp adheres tightly to the outer surface of the aleurone layer and is thought to impartsemipermeable properties to the corn kernel. All parts of the pericarp are composed of 4 Riahi and Ramaswamy Fig. 2 Diagram of corn kernel. (From Potter, 1.) dead cells that are cellulosic tubes. The innermost tube-cell layer is row of longitudinal tubes pressed tightly against the aleurone layer. This layer is covered by thick and rathercompact layer, known as the mesocarp, composed of closely
