A walnut is the nut of any tree of the genus Juglans. A walnut is the edible seed of a drupe, and thus not a true botanical nut. It is commonly consumed as a nut. After full ripening for its edible seed when the shell has been discarded, it is used as a garnish or a snack.
Walnuts are enclosed in a brown seed coat that contains antioxidants. The antioxidants protect the oil-rich seed from atmospheric oxygen, thereby preventing rancidity and keeping walnuts fresh.
The walnut tree wakes up in the second half of spring from hibernation. Walnut types are divided into two categories: I. the Persian or English walnut and black walnuts.
The English walnut originated in Iran and the black walnut is native to eastern North America. The black walnut is of high flavor, but due to its hard shell it is mostly used for the commercialization of walnuts.
China accounts for 51% of world walnut production, followed by the United States, Iran and Turkey.
