74-462: The CDC is the largest employer in Cameroon and has helped the "bottle neck" Cameroonians and the country in a cultural way. Most of the first workers in Cameroon worked on its plantations. From wages earned on these plantations, millions of Cameroonians have received an education on the corrupt nature of the leadership. The CDC operates in groups, with each group controlling its own crop. For example

148-538: A capacity of 800,000 tons per year and produces hydrodeoxygenated NEXBTL biodiesel from palm oil imported from Malaysia and Indonesia. Significant amounts of palm oil exports to Europe are converted to biodiesel (as of early 2018: Indonesia: 40%, Malaysia 30%). In 2014, almost half of all the palm oil in Europe was burned as car and truck fuel. As of 2018, one-half of Europe's palm oil imports were used for biodiesel. Use of palm oil as biodiesel generates three times

222-767: A carcinogen). Reports of indigenous peoples and communities in Indonesia, indicate losing farmland and traditionally significant land due to palm oil industry expansion. In 2017, there were over 650 different land disputes between palm oil plantations and indigenous land owners. Indigenous communities also expressed concern over the loss of natural resources, such as wild rubber, reed, and adat forests (communal forests). Indigenous communities have made some ground when it comes to land disputes, either through protest or legal means. Other concerns when it comes to indigenous communities being impacted include lack of government oversight on palm oil plantations, political corruption, or

This can occur after a month or two of consumption of beta-carotene rich foods, such as carrots, carrot juice, tangerine juice, mangos, or in Africa, red palm oil. β-carotene dietary supplements can have the same effect. The discoloration extends to palms and soles of feet, but not to the white of the eye , which helps distinguish the condition from jaundice . Carotenodermia

444-513: 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

518-477: A lot of palm nut species, which may become an important contributor to the agriculture of the region. Although Ghana has multiple palm species, ranging from local palm nuts to other species locally called agric, it was only marketed locally and to neighboring countries. Production is now expanding as major investment funds are purchasing plantations, because Ghana is considered a major growth area for palm oil. Kenya 's domestic production of edible oils covers about

592-443: A lower risk of all-cause mortality. The highest circulating beta-carotene category, compared to the lowest, correlated with a 37% reduction in the risk of all-cause mortality, while the highest dietary beta-carotene intake category, compared to the lowest, was linked to an 18% decrease in the risk of all-cause mortality. Age-related macular degeneration (AMD) represents the leading cause of irreversible blindness in elderly people. AMD

666-462: A quarter of the burned area. The widespread deforestation and other environmental destruction in Indonesia, much of which is caused by palm oil production has often been described by academics as an ecocide . Environmental groups such as Greenpeace and Friends of the Earth oppose the use of palm oil biofuels, claiming that the deforestation caused by oil palm plantations is more damaging for

740-499: A region accounts for 52.5 million metric tons (57.9 million short tons) of palm oil production, about 85% of the world total and more than 90% of global exports. Indonesia accounts for 52% of world exports. Malaysian exports total 38%. The biggest consumers of palm oil are India, the European Union, and China, with the three consuming nearly 50% of world exports. Thailand's Department of Internal Trade (DIT) usually sets

Palm oil 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 they are frequently favored by food manufacturers. Globally, humans consumed an average of 7.7 kg (17 lb) of palm oil per person in 2015. Demand has also increased for other uses, such as cosmetics and biofuels, encouraging

1184-422: 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. Palm oil

1258-472: 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 remove 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

1332-457: Is a pro vitamin A compound, converting in the body to retinol (vitamin A). In foods, it has rich content in carrots , pumpkin , spinach , and sweet potato . It is used as a dietary supplement and may be prescribed to treat erythropoietic protoporphyria , an inherited condition of sunlight sensitivity. β-carotene is the most common carotenoid in plants. When used as a food coloring , it has

1406-413: Is a source of Vitamin A and Vitamin E. Crude PO can be refined to remove its non-triglyceride components. 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

1480-450: Is an oxidative stress, retinal disease that affects the macula, causing progressive loss of central vision. β-carotene content is confirmed in human retinal pigment epithelium. Reviews reported mixed results for observational studies, with some reporting that diets higher in β-carotene correlated with a decreased risk of AMD whereas other studies reporting no benefits. Reviews reported that for intervention trials using only β-carotene, there

1554-477: Is applied to wounds for its supposed antimicrobial effects, research does not confirm its effectiveness. In 2023–2024, world production of palm oil was 77.3 million tonnes , led by Indonesia with 57% of the total. The annual production of palm oil is projected to reach 240 million tonnes by 2050. During the 2022 food crises instigated by the Russian invasion of Ukraine and crop failures in other parts of

1628-519: Is associated with a 6% increase in the risk of all-cause mortality , while low-dosage (<9.6 mg/day) supplementation does not have a significant effect on mortality. Research is insufficient to determine whether a minimum level of beta-carotene consumption is necessary for human health and to identify what problems might arise from insufficient beta-carotene intake. However, a 2018 meta-analysis mostly of prospective cohort studies found that both dietary and circulating beta-carotene are associated with

1702-495: Is called palm olein . It is also possible to fractionate at a different point of processing, even with crude palm oil. RBD PO, or "palm shortening ", is extensively used in food manufacture. It is valued for its low polyunsaturated fat content, which offers high stability against rancidity and allows it to replace hydrogenated fats in a variety of baked and fried products. The highly saturated nature of palm oil renders it solid at room temperature in temperate regions, making it

1776-460: Is called a "crude palm oil" or a " red palm oil ", referring to its intense color due to the high carotenoid 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

1850-596: Is created through a process called transesterification . Palm oil biodiesel is often blended with other fuels to create palm oil biodiesel blends. Palm oil biodiesel meets the European EN 14214 standard for biodiesels. Hydrodeoxygenated biodiesel is produced by direct hydrogenolysis of the fat into alkanes and propane. The world's largest palm oil biodiesel plant is the €550 million Finnish-operated Neste Oil biodiesel plant in Singapore , which opened in 2011 with

1924-609: Is encoded by the BCO1 gene. A lesser amount is metabolized by the mitochondrial enzyme beta-carotene 9',10'-dioxygenase, which is encoded by the BCO2 gene. The products of this asymmetric cleavage are two beta-ionone molecules and rosafluene. BCO2 appears to be involved in preventing excessive accumulation of carotenoids; a BCO2 defect in chickens results in yellow skin color due to accumulation in subcutaneous fat. For counting dietary vitamin A intake, β-carotene may be converted either using

1998-472: Is greater bioavailability compared to that from foods. At the enterocyte cell wall, β-carotene is taken up by the membrane transporter protein scavenger receptor class B, type 1 (SCARB1). Absorbed β-carotene is then either incorporated as such into chylomicrons or first converted to retinal and then retinol, bound to retinol binding protein 2 , before being incorporated into chylomicrons. The conversion process consists of one molecule of β-carotene cleaved by

2072-517: Is industrially made either by total synthesis (see Retinol § Industrial synthesis ) or by extraction from biological sources such as vegetables, microalgae (especially Dunaliella salina ), and genetically-engineered microbes. The synthetic path is low-cost and high-yield. Medical authorities generally recommend obtaining beta-carotene from food rather than dietary supplements. A 2013 meta-analysis of randomized controlled trials concluded that high-dosage (≥9.6 mg/day) beta-carotene supplementation

2146-469: Is masked by chlorophyll in green leaf vegetables such as spinach , kale , sweet potato leaves, and sweet gourd leaves. The U.S. Department of Agriculture lists foods high in β-carotene content: Milligrams per 100 g Government and non-government organizations have not set a dietary requirement for β-carotene. Excess β-carotene is predominantly stored in the fat tissues of the body. The most common side effect of excessive β-carotene consumption

2220-402: 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. Humans used oil palms as far back as 5,000 years. In

2294-682: 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

They harvest palm fruit from small farms and the palm oil is mostly used for local consumption. Cameroon had a production project underway initiated by Herakles Farms in the United States. However, the project was halted under the pressure of civil society organizations in Cameroon. Before

2738-503: Is the world's second largest producer of palm oil, producing 19.7 million tonnes in 2023-24. In 1992, in response to concerns about deforestation , the Government of Malaysia pledged to limit the expansion of palm oil plantations by retaining a minimum of half the nation's land as forest cover . As of 2023-24, Nigeria was the fifth-largest producer, with 1.5 million tonnes. Both small- and large-scale producers participate in

2812-461: 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

This has significant impacts on the local ecosystems leading to deforestation and biodiversity loss . For example, these processes have resulted in significant acreage losses of the natural habitat of the three surviving species of orangutan . One species in particular,

3034-932: The Sumatran orangutan , has been listed as critically endangered because of habitat loss due to palm oil cultivation. In addition to environmental concerns, palm oil development in regions that produce it has also led to significant social conflict . Regions with fast growing palm oil production have experienced significant violations of indigenous land rights, influxes of illegal immigrant labor and labor practices, and other alleged related human rights violations. The palm oil industry has had both positive and negative impacts on workers, indigenous peoples and residents of palm oil producing communities. Palm oil production provides employment opportunities, and has been shown to improve infrastructure , social services and reduce poverty. However, in some cases, oil palm plantations have developed lands without consultation or compensation of

As of 2019, over 401,814 ha of palm oil concessions have been awarded to 44 companies. 60% of the awarded concessions consist of forests and native vegetation, and some concessions overlap with national parks, including Tanintharyi and Lenya National Parks , which have seen deforestation and threaten conservation efforts for endemic species like

5180-534: The world due to extreme weather caused by climate change , the Indonesian government banned exports of palm oil. This combined with a reduced harvest in Malaysia greatly increased global prices, while reducing availability causing ripple effects in the global supply chain. On 23 May 2022, the Indonesian government reopened trading hoping to balance supplies. Indonesia is the world's largest producer of palm oil, producing 44 million tonnes in 2023-24. Malaysia

5254-438: The world's total vegetable oil supply. In terms of oil yield, a palm plantation is 10 times more productive than soybean , sunflower or rapeseed cultivation because the palm fruit and kernel both provide usable oil. Palm oil has garnered criticism from environmentalists due to the environmental importance of where it is grown. However, it is indisputably more efficient in comparison to other oil-producing plants. In 2016, it

5328-591: Was developed 1967 by the United Nations/ World Health Organization Food and Agriculture Organization (FAO/WHO). Another older unit of vitamin A activity is the international unit (IU). Like retinol equivalent, the international unit does not take into account carotenoid variable absorption and conversion to vitamin A by humans, as well as the more modern retinol activity equivalent. Unfortunately, food and supplement labels still generally use IU, but IU can be converted to

5402-526: Was found that palm oil farms produce around 4.17 metric tons of oil per hectare. By contrast other oils, such as sunflower, soybean, or peanut only produce 0.56, 0.39, and 0.16 metric tons respectively per hectare. Palm oil is the most sustainable vegetable oil in terms of yield, requiring one-ninth of land used by other vegetable oil crops. In the future, laboratory-grown microbes might achieve higher yields per unit of land at comparable prices. However, palm oil cultivation has been criticized for its impact on

5476-646: Was no change to risk of developing AMD. A meta-analysis concluded that supplementation with β-carotene does not appear to decrease the risk of cancer overall, nor specific cancers including: pancreatic, colorectal, prostate, breast, melanoma, or skin cancer generally. High levels of β-carotene may increase the risk of lung cancer in current and former smokers. Results are not clear for thyroid cancer. A Cochrane review looked at supplementation of β-carotene, vitamin C, and vitamin E, independently and combined, on people to examine differences in risk of cataract , cataract extraction, progression of cataract, and slowing
