Indonesia Coconut Copra For Sale
Once the oil is extracted, the remaining coconut cake is 18–25% protein but contains so much dietary fiber it cannot be eaten in large quantities by humans. Instead, it is normally fed to ruminants.

The production of copra – removing the shell, breaking it up, drying – is usually done where the coconut palms grow. Copra can be made by smoke drying, sun drying, or kiln drying. Hybrid solar drying systems can also be used for a continuous drying process. In a hybrid solar drying system, solar energy is utilized during daylight and energy from burning biomass is used when sunlight is not sufficient or during night. Sun drying requires little more than racks and sufficient sunlight. Halved nuts are drained of water, and left with the meat facing the sky; they can be washed to remove mold-creating contaminants. After two days the meat can be removed from the shell with ease, and the drying process is complete after three to five more days (up to seven in total). Sun drying is often combined with kiln drying, eight hours of exposure to sunlight means the time spent in a kiln can be reduced by a day and the hot air the shells are exposed to in the kiln is more easily able to remove the remaining moisture. This process can also be reversed, partially drying the copra in the kiln and finishing the process with sunlight. Starting with sun drying requires careful inspection to avoid contamination with mold while starting with kiln-drying can harden the meat and prevent it from drying out completely in the sun.
Copra is highly susceptible to the growth of molds and their production of aflatoxins if not dried properly. Aflatoxins can be highly toxic, and are among the most potent known natural carcinogens, particularly affecting the liver.Aflatoxins in copra cake, fed to animals, can be passed on in milk or meat, leading to human illnesses.
Copra meal is used as fodder for horses and cattle. Its high oil and protein levels are fattening for stock. The protein in copra meal has been heat treated and provides a source of high-quality protein for cattle, sheep and deer, because it does not break down in the rumen.
Coconut oil can be extracted using either mechanical expellers or solvents (hexane). Mechanically expelled copra meal is of higher feeding value, because it contains typically 8–12% oil, whereas the solvent-extracted copra meal contains only 2–4% oil. Premium quality copra meal can also contain 20–22% crude protein, and <20ppb aflatoxin.
High-quality copra meal contains <12% non structural carbohydrate (NSC), which makes it well suited for feeding to horses that are prone to ulcers, insulin resistance, colic, tying up, and acidosis.
