A
walnut is the nut of any tree of the genus particularly the Persian
or English walnut Walnuts are
rounded, single-seeded stone fruits of the walnut tree commonly
used for the meat after fully ripening. Following full ripening,
the removal of the husk reveals the wrinkly walnut shell, which is
usually commercially found in two segments. During the ripening
process, the husk will become brittle and the shell hard. The shell
encloses the kernel or meat, which is usually made up of two halves
separated by a partition. The seed kernels commonly available as
shelled walnuts are enclosed in a brown seed coat which contains
antioxidants. The antioxidants protect the oil-rich seed from
atmospheric oxygen, thereby preventing.
