Studies in interspecific hybrids showed that the palm oil composition profile is intermediate between those of the two parental Elaeisspecies for most fatty acids, which is an advantage for introgressing these traits from E. oleiferainto varieties of E. guineensis[4], [7], [25]. International Union of Pure and Applied Chemistry. The oil-soluble, vitamin-like substance structurally resembles with vitamin K, which includes a 1,4-benzoquinone head and a side chain consisted of 6–10 isoprenyl subunits. Phosphatides, as the principal constituent of gums in the crude oil, severely interfere with the efficiency of subsequent process steps if allowed to remain. Phosphatides can be either soluble or weakly soluble in water and thus giving rise to two types of gums: • Non-hydratable gums       – Can be removed by acid treatment Besides the role of providing a source of vitamin, carotenoids are considered to have anti-carcinogenic properties. Both these essential fatty acids are present in palm oil. Triacylglycerol is the basic unit of oils and fats that determines their characteristics. Note that from the table above, the longer the carbon chain (i.e C16 and C17) , the higher the melting point. These elements make up molecules of fatty acids and glycerol, which combine to form fat molecules known as triacylglycerols. Inorganic phosphate is observed to increase with the content of free fatty acid and pro-oxidant metals, especially in poor quality oils. Data for palm kernel oil taken from the Canadian Food Composition Data Base. I really appreciate this, helpful though. An unsaturated fatty acid with a double bond can have two possible configurations, either cis or trans, depending on the 18        – indicates the number of carbon in the molecule, Therefore, great efforts are undertaken to separate certain triacylglycerols or to change their distribution in the glycerol molecule. Alkyl group refers to the carbon-hydrogen chain of the fatty acids. myristic (14:0, 2%), Coenzyme Q10 (CoQ10) is the most common ubiquinone in palm oil. Pesticides are used to increase agriculture production throughout the world. Palm stearin consists of mostly glyceryl tri palmitate, with most of the rest of the fat content being glyceryl dipalmitate mono oleate. Palm oil mill effluent is a highly polluting material and much research has been dedicated to means of alleviating its threat to the environment. Most of the loss occurs at deodorisation, and consequently palm fatty acid distillate (PFAD) has up to five to ten times the level in crude oil. This composition results in an edible oil that is suitable for use in a variety of food applications. palmitic (16:0, 11%), This is a result of mainly milling practice. Squalene is a triterpene with 30 carbon atoms, containing six isoprene units, and it is known as an intermediate in the biosynthesis of sterols. During storage and transportation, care should be taken to prevent the oil from being contaminated by moisture or metal (especially copper or bronze), all which promote hydrolysis. Trace quantities of copper, iron, manganese, and nickel substantially reduce the oxidative stability of fats and oils, whereas calcium, sodium, and magnesium reduce the efficiency of the refining, degumming, bleaching, and hydrogenation systems. Triacylglycerols (Triglycerides) Carotenes preferentially segregate into the more unsaturated olein fraction, leaving little in the stearin fraction. Tocotrienols have become a focus of research in recent years because of findings showing high efficacy in protecting against heart related diseases and certain cancers. The most important essential fatty acids are linoleic acid and linolenic acid, the parent fatty acids of the omega-6 and omega-3 families respectively. The rest of the fruit comprises the shell, kernel, moisture and other non-fatty fibres. Great attention should be given during the various steps of the process to minimize the amount of FFA in the starting or finished oil products. Loaded With Antioxidants. Researchers are only on the cusp of understanding how fatty acids work independently and in conjunction with other nutrients to impact our health. If there is more than one double bond in a fatty acid, then it is known as polyunsaturated. or Elaeis melanococca auct.). Palm stearin is the harder fraction of palm oil, containing a higher proportion of saturated fatty acids and TAGs with a higher melting point of 48–50°C. The fatty acid composition of the palm oil is 40-52% oleic acid, 35-45% palmitic acid, 5-10% lineoleic acid, 3-8% stearic acid and 2-5% myristic acid, giving it a higher unsaturated acid content than palm kernel oil … In the case of oils & fats, the carboxylic acids consist of fatty. Palm kernel oil forms a eutectic with palm oil in a mixture containing about 30% palm kernel oil. Registered office: 3 Clanricarde Gardens, Tunbridge Wells, Kent TN1 1HQ, United Kingdom.© 2021 M.P. Effect of carbon chain length and unsaturation on melting points of fatty acids. p. 31. Fatty acids can used as animal feed or sold to oleochemical producers for production of soaps and other specialised chemicals. Change ). If more than one double bond exists, the melting point drops further (C18:1 and C18:2). Palm oil is a different product from palm kernel oil, which is extracted from the fruit kernels. Data for palm kernel oil taken from the Canadian Food Composition Data Base. Create a free website or blog at WordPress.com. Both glycolipids and phospholipids are almost completely removed in refining processes; therefore, their content in commercial palm oil is very low. 28% global deforestation by agriculture. Thus triolein is the triglyceride of oleic acid, tripalmitin that of palmitic acid, tristearin that of stearic acid, while monopalmitin-distearin contains, as the name indicates, one molecule of palmitic and two of stearic acid. Change ), You are commenting using your Google account. Palm oil is obtained from the fruit of the oil palm tree. Fats and oils are practically always mixtures of triglycerides in varying proportions. Palm oil's nutritional profile is similar to other cooking oils, according to the USDA. The differences are in color (raw palm kernel oil lacks carotenoids and is not red), and in saturated fatcontent: palm mesocarp oil is 49% saturated, while palm kernel oil and coconut oil are 81% and 86% saturated fats, respectively. cis configuration. Unlike tocotrienols and carotenes, the content of phytosterols in palm oil is relatively lower than that in other oils. The most widely used chelating agents are citric and phosphoric acids. ( Log Out /  See figure 2-2, page 20 for global figures: ‘Global Gross deforestation 1990-2008’. Cambridge, Royal Socieyt of Chemistry. https://www.nutritionadvance.com/red-palm-oil-nutrition-benefits Its use in this region dates back more than 5,000 years. Potential Health Risks. Squalene in CPO, refined oil, pressed fiber oil, and PFAD are reported to be 200–600 ppm, 415 ppm, 1000–1800 ppm, and 12,000–18,000 ppm, respectively. Good milling will reduce moisture, dirt as well as metal contamination in palm oil. Palm oil contains approximately 44% palmitic acid (saturated), 5% stearic acid (saturated), 39% oleic acid (monounsaturated), and 10% linoleic acid (polyunsaturated). oleic (18:1, 34%), With a sufficient amount of Vitamin E, rarely found tocotrienols and being … These are myristic acid, lauric acid, palmitic acid, stearic acid, oleic acid, linolic acid, and linolenic acid. All rights reserved. HISTORY OF PALM OIL. NOTE – Fatty Acid Nomenclature An industrial oil palm mill produces about 2.5 t of effluent per tonne of palm oil, or 0.5 tonne of effluent per tonne of fresh fruit (Ho et al., 1984; Pérez, 1997). Squalene is reported to have anti-carcinogenic activity against skin, colon, and lung cancer. ( Log Out /  Both access 16/12/2019. Unlike other vegetable oil, palm oil also contains almost equal quantities of saturated (palmitic 45% and stearic acid 4%) and unsaturated acids (oleic 40% and linoleic … It’s odourless, high in unsaturated fats (and without trans-fats), incredibly resistant to spoilage, and has a high smoking point. Bailey’s Industrial Oil and Fat Products, Wiley, 2005 Fatty acids hydrocarbon chain consist mainly of even number of carbons (from 4 to 28). Registered in England No. 7. These qualities make it perfect for a range of applications. Sources: McCance and Widdowson's The Composition of Foods Integrated Data Set 2019. Carotenoids have long been known for their pro-vitamin A activity, as they can be transformed into vitamin A in vivo. 12c      – Since this fatty acids has 2 double bond, the 2nd double bond is indicated on Fat Composition Analysis Available data suggests that 100 g of palm oil contains: 37% of monounsaturated fat, 9.3% of polyunsaturated fat, and 49.3% of saturated fat out of a total lipid of 100 g. The amount of trans fat is not available. During harvesting, hydrolysis of triglycerides does not occur in undamaged fruit, presumably because the lipase is compartmentalised within the cell and only comes into contact with the oil if cell membranes are damaged. The common commercial source of natural vitamin E (soy, corn, cottonseed, sunflower, and canola oil) contained little or no tocotrienols. In addition, squalene is a powerful antioxidant which can scavenge free radicals from the body and thus reduce free radical oxidative damage to the skin. It is used as a food oil, and in industrial applications. linoleic (18:2, 34%), Palm kernel oil, which is semi-solid at room temperature, is more saturated than palm oil and comparable to coconut oil. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Commonly recognized as the tall, towering, ornamental garden tree that grows along streets and walking paths, the Palm tree has become one of the world’s most cultivated botanicals due to the flesh of its fruits and the fruits’ kernels, which yield the versatile Palm Carrier Oil and Palm Kernel Carrier Oil. (3) Position of the double bonds in the chain. The fatty acids are labelled according to the number of carbon in the molecule as indicated in the column ‘chain’. Phytosterols have been the subject of many nutritionists because of their bioactivities such as cholesterol-lowering actions and anti-cancer effects. Good oils having lower amount of mono and diglycerides is said to be of great importance in the fractionation process because they act as emulsifying agents inhibiting crystal formation and making filtration difficult. Cooking oil is purified fat of plant/animal origin, which is usually liquid at room temperature (saturated oils such as coconut and palm are more solid at room temperature than other oils). Phytosterols are important structural components of plant membranes. Crude palm oil contains approximately 1% of minor constituents including carotenoids, tocopherols, tocotrienols, sterols, phospholipids, triterpene alcohols, squalene, aliphatic alcohols and aliphatic hydrocarbons.

Vitamin A is necessary for vision, growth, cellular differentiation, morphogenesis, and several other cellular and physiologic functions. During refining, the bleaching and steam deodorisation processes partially remove some of these valuable components. Triacylglycerol means there are three (tri) molecules from the acyl group (carboxylic acids) attached to a glycerol molecule. The practical method to extract vitamin E is from palm fatty acid distillate (PFAD), in which the total tocopherols and tocotrienols are concentrated to 0.4–0.5% (w/w). 8. Crude palm oil, extracted commercially by sterilisation and press, contains 500–700 ppm of carotenoids, the variation being due to process conditions, species of oil palm and level of oxidation. Industrially, mono and diacylglycerols are produced by partial hydrolysis or glycerolysis of triacylglycerols for use as food grade emulsifiers. On average, palm oil has almost equal amounts of saturated and unsaturated fatty acids. 2. An example is C18:3 cis configuration has a much lower melting point than C18:3 trans configuration. Change ), You are commenting using your Facebook account. It has high levels of saturated fat, causing some health authorities to recommend limiting consumption of coconut oil as a food. Sterols are high-melting polycyclic alcohols of the general structure: Phytosterols or plant sterols form a major part of the unsaponifiable fraction of palm oil. Certain polyunsaturated fatty acids cannot be made in the body and small amounts need to be supplied in the diet and are called essential fatty acids. Phosphatides darkens the colour of an oil if they become broken down by heat; and can lead to impaired flavour stability. World Conference: Processing of Palm, Palm Kernel and Coconut Oil Proceedings,  AOCS, 1985 Palm Oil Quality Standards for Trading, MPOB, 2013 Most of the saturated fatty acids occurring in nature have unbranched structures with an even number of carbon atoms. Balanced composition. This oil contains 50% of saturated fat, 40% monounsaturated fatty acid, 10 % polyunsaturated fatty acid, carotenoids, sterols, vitamin E, A, antioxidants, flavonoids and phenolic acids. Palm oil is the largest natural source of tocotrienol, part of the vitamin E family. Fatty acids are defined as compounds that are composed of long chains of carbon and hydrogen atoms (referred to as hydrocarbon molecules) containing a carboxylic acid moiety at one end (a carboxylic acid is written –COOH). 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). This has important consequences for the oxidative stability of these two fractions. The Stationery Office. Though the number of triglycerides encountered in nature is great, the triglycerides of these seven acids (see table of formulas below) make up the great bulk of the natural fats and oils. Most naturally occurring unsaturated fatty acids exist in the cis configuration. Reference: Tocotrienols are extracted commercially from palm oil and rice bran oil. At present, some products containing phytosterols are available in the market, especially in several European countries. Ubiquinone is another interesting and valuable minor component present in palm oil. American oil palm is a low-yielding species, but the oil quality and composition is better than that of the African species. Crude palm olein has a higher content of tocopherols and tocotrienols. lauric (12:0, 4%), ( Log Out /  Sources: McCance and Widdowson's The Composition of Foods Integrated Data Set 2019. Those by-products are known as fatty acid distillate (FAD). Palm oil is distinguished from other oil by its high level of palmitic acid (C16:0). McCance and Widdowson's The Composition of Fooods Seventh Summary edition. In palm oil sterols, sitosterol (60%), campesterol (13%) and stigmasterol (24%) are the major constituents while a minor amount of cholesterol (3%) is present. The palm oil and palm kernel oil are composed of fatty acids, esterified with glycerol just like any ordinary fat. The main source of phytosterols in large scale production is the by-products from the process of refining oils. Crude palm oil contains the highest concentration of natural carotenoids, which proves it to be the most promising plants for carotenes sources in nature. There is growing interest in developing functional foods, including vegetable oils, spreadable fats, butter, yogurt, bakery products, juice, and milk, in which different types of phytosterols are intrinsic or just added as novel food ingredients to fortify the health-promoting effect of those products. The main responsibility for this last ill-effect, however, is linked with traces of pro-oxidant iron liable to persist in refined oil along with the gummy material rather than phosphatides themselves. The main source of palm oil is the Elaeis guineensis tree, which is native to West and Southwest Africa. If every carbon atom has its full quota of hydrogen atoms, the fatty acid is saturated. Palm oil is naturally reddish in color because of a high beta-carotene content. Palm kernel oil is similar to coconut oil in terms of composition, and is produced by mechanical extraction of the kernels which are pre-dried in palm oil mills through a partial vacuum process. The terms cis and trans are from Latin, in which cis means “on the same side” and trans means “on the other side”. Unsaturated fatty acids are further divided into those that contain one (monounsaturated) or two or more (polyunsaturated) double bond linkages. Carotenes and tocopherols are antioxidants and stabilise the oil against oxidation. They may also be present as glucosides. Isomers are defined as compounds with the same molecular formula but different molecular structure. Where Ra, Rb, Rc represents the hydrocarbon chain in a fatty acid molecule. Palm oil vs Vegetable oil - In-Depth Nutrition Comparison. Palm oil comes from the fleshy fruit of oil palms. Palm oil has a balanced ratio of unsaturated and saturated fatty acids. Since there are a number of different fatty acids that occur in natural fats, a great many different triglycerides are encountered in nature. 4. Comparison of the vitamin E content of palm oils and other major vegetable oils. The oil palm gives its name to the 16 carbon saturated fatty acid palmitic acid found in palm oil; monounsaturated oleic acid is also a constituent of palm oil while palm kernel oil contains mainly lauric acid. Processing studies have shown that neither solvent extraction nor bleaching affects the pesticide levels in oils; however, it was found that pesticides are removed by volatilization during deodorization. 3. Nutrient Composition. The amounts retained in the refined oils depend on the conditions of refining. Fatty acids consist of chains of carbon atoms linked together rather like a paper chain. Carotenoids are a family of compounds of more than 600 fat-soluble plant pigments that provide much of the colour we see in nature. Mean values Composition based on Codex Standards for Fats and Oils from Vegetable Sources (CODEX-STAN 210 - 1999) Source: McCance and Widdowson's The Composition of Foods Integrated Data Set 2019. Palm oil owes its popularity to its chemical composition. The major components are α-carotene and β-carotene. They produce the beautiful colours of many birds, insects, and marine animals as well as the colours of many flowers and fruits. Frying Oil; 31. Compare Canola to Palm oil by vitamins and minerals using the only readable nutrition comparison tool. Comparison of the proportions of saturated and unsaturated fats in palm oils and other vegetable oils, Comparison of the vitamin E content of palm oils and other major vegetable oils, https://www.gov.uk/government/publications/composition-of-foods-integrated-dataset-cofid, https://food-nutrition.canada.ca/cnf-fce/search-rechercher.do;jsessionid=B71D6F2DDB1BBBFA0516715C001B8095, http://palmoilis.mpob.gov.my/publications/POD/pod12-4.pdf. Because of its nearly equal fatty acids composition - 50% saturated and 50% unsaturated - palm oil can be fractionated for different uses, i.e. Palm oil is used for preventing and treating vitamin A deficiency. 1997 These are either absorbed onto the bleaching earths or destroyed during thermal treatment. Physically refined oils show no trace of the carotenoids. Triacylglycerol is a chemical compound consisting of three elements; carbon, hydrogen and oxygen. α-linolenic (18:3, 5%) 1555042. Therefore, phytosterols are concentrated in the FAD, and this is the common industrial method to obtain phytosterols from vegetable oils since the concentration of phytosterols intrinsic in vegetable oils is low. Residual phosphorus in bleached and deodorized oil caused by poor processing or treatment also is known to correlate well with the free fatty acid escalation during transport. Iron impurities are derived from the wear and tear of oil mill machinery and can be minimised by using stainless steel at strategic points in the milling process. The picture above shows cis-trans isomerism where the molecule has two possible orientations. Vegetable Oil in Food Technology, Blackwell Publishing, 2002 the 12th carbon with a cis configuration. Change ), You are commenting using your Twitter account. It May Have Health Benefits. 1. Fatty Acid Composition of Palm Oil, Palm Oil Fractions and Palm Kernel Oil, Increase in Demand for Heart Health Supplements | Natural Health Information, Molecular Weight Of Palm Oil - Chemical Literature, Follow Oil Palm Knowledge Base on WordPress.com, Medium-chain fatty acids (MCFA) are fatty acids with, Long-chain fatty acids (LCFA) are fatty acids with. 5. 6. High FFA in crude oil will cause greater refining loss. Products that don’t contain palm oil . Physical refining invariably causes some loss (15-57%) of the tocopherols; therefore, over vigorous conditions need to be avoided. African oil palm is commercially cultivated and a high-yielding species. In addition to anticancer effects, tocotrienol-rich fractions of palm oil have hypocholesterolaemic effects in humans and offer protection against heart diseases. Introduction to Oils & Fats Technology, AOCS Press, 2000 Canola vs Palm oil - In-Depth Nutrition Comparison. The quality of the oil is excellent, with free fatty acids of the crude oil generally below 2%. Translocation to oil-bearing plant seeds has also been demonstrated. Glycolipids, although present in larger amounts than phospholipids, do not appear to contribute much to the quality of crude palm oil. The ratio depends on the type of oil or fat. Inorganic phosphorus and phospholipids are two forms of phosphorus compounds in CPO, with inorganic phosphorus being the most predominant. Saturated and monounsaturated fatty acids can be made in the body and are also widely present in both vegetable and animal fats. Palm Oil: Good or Bad? It contains 40% oleic acid (monounsaturated fatty acid), 10% linoleic acid (polyunsaturated fatty acid), 45% palmitic acid and 5% stearic acid (saturated fatty acid).
