Copra is the dried flesh of the coconut. Copra is one of the most important coconut derivative products, because it is the raw material for making coconut oil and its derivatives. To make good copra, you need a coconut that is about 300 days old and weighs about 3-4 kg.
There are four kinds of copra processing techniques: sun drying; drying by smoking or smoking over a fire (smoke curing or drying); drying by indirect heating (indirect drying); and drying using a solar system (solar heat energy).
Good copra should only have a water content of 6% – 7%. It is not susceptible to nuisance organisms. Damage that occurs in copra is generally caused by bacterial and fungal attacks. The attack is easy to occur if the water content in copra is high, the humidity reaches 80% or more and the atmospheric temperature reaches 30°C. Fungi that often attack copra are the fungus Rhizopus sp, Aspergillus niger, and Penicillium Glaucum. There are 4 qualities of copra, which include high-grade copra and mixed copra.
