| The
endosperm accounts
for about 82 percent of the kernel’s dry weight
and is the source of energy (starch) and protein for the
germinating seed. Starch is the most widely used part
of the kernel and is used as a starch in foods—or
as the key componentin fuel, sweeteners, bioplastics and
other products. |
The
pericarp is the outer covering that
protects the kernel and preserves the nutrient value
inside. It resists water and water vapor—and is
undesirable to insects and microorganisms. |
| The
germ
is the only living part ofthe corn kernel. The germ contains
the essential genetic information,enzymes, vitamins and
minerals for the kernel to grow into a corn plant. About
25 percent of the germ is corn oil—the mostvaluable
part of the kernel, which is high in polyunsaturated fats
and has a mild taste. |
| The
tip cap
is the attachmentpoint of the kernel to the cob, through
which water and nutrients flow—and is the only area
of the kernel not covered by the pericarp. |
