COCONUT


Copra

Copra is the dried meat, or kernel, of the coconut. The name copra is derived from the Malayalam word koppara for dried coconut. It is the principal commercial product derived from the coconut palm, and is used primarily as a source of coconut oil. The resulting residue, coconut oil cake, is used as livestock feed. Coconut oil was introduced as a source of edible fat in northern Europe in the 1860’s because of a shortage of dairy fats. Early in the 20th century it became known in the United States.

There are two types of copra namely milling and edible. Milling copra is used to extract oil while edible grade of copra is consumed as a dry fruit and used for religious purposes.

The oil content, the color and appearance, and the moisture content of copra are variable. These characteristics are used for grading copra.
