Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of oil palms. The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 36% of global oils produced from oil crops in 2014. Palm oils are easier to stabilize and maintain quality of flavor and consistency in ultra-processed foods, so are frequently favored by food manufacturers. On average globally, humans consumed 7.7 kg (17 lb) of palm oil per person in 2015. Demand has also increased for other uses, such as cosmetics and biofuels, creating more demand on the supply encouraging the growth of palm oil plantations in tropical countries. The use of palm oil has attracted the concern of environmental and human right groups. The palm oil industry is a significant contributor to deforestation in the tropics where palms are grown, and has been cited as a factor in social problems due to allegations of human rights violations among growers. An industry group formed in 2004 to create more sustainable and ethical palm oil, through the Roundtable on Sustainable Palm Oil. However, very little palm oil is certified through the organization, and some groups have criticized it as greenwashing. In 2018, a report by the International Union for Conservation of Nature acknowledged that palm oil is much more efficient than other oils in terms of land and water usage; however, deforestation causes more biodiversity loss than switching to other oils. The biggest global producers of palm oil are Indonesia, who produced 60% of it in 2022, followed by Malaysia, Thailand, and Nigeria. Indonesia produces biodiesel primarily from palm oil. History 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. European merchants trading with West Africa occasionally purchased palm oil for use as a cooking oil in Europe. Palm oil became a highly sought-after commodity by British traders for use as an industrial lubricant for machinery during Britain's Industrial Revolution. Palm oil formed the basis of soap products, such as Lever Brothers' (now Unilever) "Sunlight" soap, and the American Palmolive brand. By around 1870, palm oil constituted the primary export of some West African countries, which often led to oppressive labor practices, as highlighted in the account of Abina Mansah's life. However, this was overtaken by cocoa in the 1880s with the introduction of colonial European cocoa plantations. Processing Palm oil is naturally reddish in color because of a high beta-carotene content. It is not to be confused with palm kernel oil derived from the kernel of the same fruit or coconut oil derived from the kernel of the coconut palm (Cocos nucifera). The differences are in color (raw palm kernel oil lacks carotenoids and is not red), and in saturated fat content: palm mesocarp oil is 49% saturated, while palm kernel oil and coconut oil are 81% and 86% saturated fats, respectively. However, crude red palm oil that has been refined, neutralized, bleached and deodorized, a common commodity called RBD (refined, bleached, and deodorized) palm oil, does not contain carotenoids. Many industrial food applications of palm oil use fractionated components of palm oil (often listed as "modified palm oil") whose saturation levels can reach 90%; these "modified" palm oils can become highly saturated, but are not necessarily hydrogenated. 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. Along with coconut oil, palm oil is one of the few highly saturated vegetable fats and is semisolid at room temperature. Palm oil is a common cooking ingredient in the tropical belt of Africa, Southeast Asia and parts of Brazil. Its use in the commercial food industry in other parts of the world is widespread because of its lower cost and the high oxidative stability (saturation) of the refined product when used for frying. One source reported that humans consumed an average 17 pounds (7.7 kg) of palm oil per person in 2015. Extraction 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. It is bottled for use as a cooking oil, in addition to other uses such as being blended into mayonnaise and vegetable oil. The result of milling or cold-pressing is a mixture of water, crude palm oil, and fibers from the palm fruit. A minimum degree of processing is required to obtain the oil. The mixture is first passed through a filter to remove the solids, then separated by density to removed the water. Density treatment can also act as a basic form of degumming, provided that the fruit is steamed before milling to hydrolyze the gum, at a cost of also losing some triglycerides to hydrolysis. The result of basic processing is called a "crude palm oil" or a "red palm oil", referring to its intense color due to the high caretinoid content. Red palm oil is a traditional cooking oil in West Africa. The free fatty acids within provide a "bite" to the flavor. The triglyceride part is around 50% saturated fat—considerably less than palm kernel oil—and 40% monounsaturated fat and 10% polyunsaturated fat. It is a source of Vitamin A and Vitamin E. Refining Crude PO can be refined to remove its non-triglyceride components. Bleaching removes color from the oil. This is achieved by adding a clay absorbent called bleaching earth in a vacuum mixer. Filters remove the clay from the oil. The oil enters the deodorizer, which is responsible for removing free fatty acids (FFA) generated by hydrolysis. One type of deodorizer works by distillating out the FFAs using a set of different temperatures. The FFA is collected as "palm fatty acid distillate" (PFAD). PFAD is itself a valuable product used in the manufacture of soaps, washing powder and other products. The final, refined oil is called "refined, bleached and deodorized palm oil" (RBD PO). RBD PO is the basic palm oil sold on the world's commodity markets. RBD PO is also known as white palm oil. It can be further fractionated using the different melting points of its components. The part with a higher melting point, which crystalizes out as a solid earlier, is called palm stearin. It consists of mostly saturated fats. The remaining liquid part is called palm olein.
