Oil palm is the most efficient oil-producing plant in the world. In Malaysia, at present, oil palm can produce about 5 tons of oil per hectare at most, and the oil yield per hectare of oil palm is five times higher than that of peanuts in the same area and nine times higher than that of soybeans. Oil palm in Malaysia has reached maturity on average, with an average annual output of 3.7 tons of crude palm oil per hectare.
Palm oil is a kind of vegetable oil, which can partially replace other oils, such as soybean oil, peanut oil, sunflower oil, coconut oil, lard and butter. Because of the relationship between palm oil and various oils and fats, the price of palm oil fluctuates with the general international oil price, and the price of palm oil fluctuates greatly.
