A kernel of rice consists of several
layers. On the left is an example of a rice grain
called true fruit or brown rice (Caryosis). In
general, each rice kernel is composed of the following
layers:
•
Rice shell
or Husk: encloses the brown rice, consists
mainly of embryo and endosperm.
•
Bran layer:
a very thin layer of differentiated tissues.
This layer contains fiber, vitamin B, protein
and fat. The most nutritious part of rice
resides in this layer.
•
Embryo:
the innermost part of rice consisting mainly
of starch called amylose and amylopactin.
The mixture of these two starches determines
the cooking texture of rice.
