In Borneo, the forest (F), is being replaced by oil palm plantations (G). These changes are irreversible for all practical purposes (H). In addition to environmental concerns, palm oil development in regions that produce it has also led to significant social conflict.
How is palm oil made?
Palm oil is traditionally, and still industrially, produced by milling the fruits of oil palm. Besides milling, palm oil is produced by cold-pressing the fruit of the oil palm since the 1990s. This type of artisanal palm oil is usually not further refined, so they keep the natural red color.
How much oil is extracted from palm kernels?
The oil palm produces bunches containing many fruits with the fleshy mesocarp enclosing a kernel that is covered by a very hard shell. The FAO considers palm oil (coming from the pulp) and palm kernels to be primary products. The oil extraction rate from a bunch varies from 17 to 27% for palm oil, and from 4 to 10% for palm kernels.
Where did palm oil come from?
Humans used oil palms as far back as 5,000 years. In the late 1800s, archaeologists discovered a substance that they concluded was originally palm oil in a tomb at Abydos dating back to 3,000 BCE. Palm oil from Elaeis guineensis has long been recognized in West and Central African countries, used widely as a cooking oil.
