This sterilization also serves to deactivate enzymes that could otherwise break down the oil, thereby extending the shelf life of the final product. The loose fruits then pass through a digester, which uses rotating, steam-heated drums to cook the fruit.

Extraction and Separation With the fruit pre-cooked, the actual extraction of the oil begins. The slurry is processed further to extract palm kernel oil, which is chemically distinct from the crude palm oil derived from the fruit pulp.
Harvesting the Fresh Fruit Bunches The first critical step in the production chain is the harvesting of Fresh Fruit Bunches (FFBs). Stage Key Purpose Sterilization Loosen fruit, deactivate enzymes Threshing Separate fruit from stalks Digestion Cook pulp for easier pressing Pressing Extract crude palm oil Clarification Remove solid impurities Refining Neutralize taste and extend shelf life.
