( Log Out / 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). 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 acid 10%). 8%. The ratio depends on the type of oil or fat. 8. World Conference: Processing of Palm, Palm Kernel and Coconut Oil Proceedings, AOCS, 1985 Loaded With Antioxidants. 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 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). 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. Both these essential fatty acids are present in palm oil. palmitic (16:0, 11%), 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 mesocarp comprises about 70 – 80% by weight of the fruit and about 45 -50% of this mesocarp is oil. Though I listed its benefits and nutrients, here you can go through the composition of palm oil. Palm oil has a balanced ratio of unsaturated and saturated fatty acids. These elements make up molecules of fatty acids and glycerol, which combine to form fat molecules known as triacylglycerols. 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. Reference: 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. While a large variety of fatty acids is found in natural fats and oils, only a few of them are of outstanding commercial importance. 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. It is used as a food oil, and in industrial applications. Therefore, great efforts are undertaken to separate certain triacylglycerols or to change their distribution in the glycerol molecule. 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 … Complex esters which contain phosphorus, nitrogen bases, sugars, and long-chain fatty acids are classed as phospholipids. The Stationery Office. If every carbon atom has its full quota of hydrogen atoms, the fatty acid is saturated. Tocotrienols are extracted commercially from palm oil and rice bran oil. 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 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 … PKO Palm Kernel Olein Palm Kernel Stearin PO POO POS Palm mid Fract 6:0 0.3 0.4 0.2 8:0 4.4 5.4 1.2 -3.5 ... •Cost saving as JGQ palm oil/olein can be used directly without re-refining on arrival at the destination point. 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. The most widely used chelating agents are citric and phosphoric acids. They are similar to oil molecules (Triglycerides) except that they are phospholipids products where one of the three fatty acid chains is substituted by a phosphatide. The palm oil and palm kernel oil are composed of fatty acids, esterified with glycerol just like any ordinary fat. Fatty acids hydrocarbon chain consist mainly of even number of carbons (from 4 to 28). 1997 cis configuration. Physically refined oils show no trace of the carotenoids. α-linolenic (18:3, 5%) 6. Palm oil owes its popularity to its chemical composition. Note that from the table above, the longer the carbon chain (i.e C16 and C17) , the higher the melting point. Phytosterols have been the subject of many nutritionists because of their bioactivities such as cholesterol-lowering actions and anti-cancer effects. The terms cis and trans are from Latin, in which cis means “on the same side” and trans means “on the other side”. Saturated and monounsaturated fatty acids can be made in the body and are also widely present in both vegetable and animal fats. Crude palm oil contains the highest concentration of natural carotenoids, which proves it to be the most promising plants for carotenes sources in nature. Introduction to Oils & Fats Technology, AOCS Press, 2000 or Elaeis melanococca auct.). stearic (18:0, 4%), Most naturally occurring unsaturated fatty acids exist in the cis configuration. Tocols, natural antioxidants found in plant-based oils, include four tocopherol and four tocotrienol isomers, each designated as alpha (α), beta (β), gamma (γ), and delta (δ) depending on the number and position of methyl groups on a chromane ring; they also possess vitamin E activity. The picture above shows cis-trans isomerism where the molecule has two possible orientations. The distribution of the 10-12 main fatty acids over the three different positions of the glycerol molecule determines the properties of the oils/fats. Since there are a number of different fatty acids that occur in natural fats, a great many different triglycerides are encountered in nature. On average, palm oil has almost equal amounts of saturated and unsaturated fatty acids. The main source of phytosterols in large scale production is the by-products from the process of refining oils. At present, some products containing phytosterols are available in the market, especially in several European countries. Translocation to oil-bearing plant seeds has also been demonstrated. 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. Squalene is reported to have anti-carcinogenic activity against skin, colon, and lung cancer. The fatty acids are labelled according to the number of carbon in the molecule as indicated in the column ‘chain’. (3) Position of the double bonds in the chain. The reaction can be autocatalytic, or catalysed by some metals or by the enzyme lipase, which is widely found in living organisms and is also present in oil palm mesocarp. Both accessed 16/12/201916 Dec 2019. Both species of oil palm are diploid (2 n =2 x =32) and are crossable. oleic (18:1, 34%), The quality of the oil is excellent, with free fatty acids of the crude oil generally below 2%. Potential Health Risks. But once there is a double bond (i.e C18 and C18:1), the melting point drops significantly. 28% global deforestation by agriculture. 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. International Union of Pure and Applied Chemistry. 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. Other components are free fatty acids (FFA), moisture, dirt and minor components of non-oil fatty matter referred to collectively as unsaponifiable matter. Palm oil is naturally reddish in color because of a high beta-carotene content. Palm kernel oil forms a eutectic with palm oil in a mixture containing about 30% palm kernel oil. Coenzyme Q10 (CoQ10) is the most common ubiquinone in palm oil. 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. Product Specification . 9c – indicates the location of double bond from the carboxyl end and c indicates The CoQ10 were report to be about 10–80 ppm in CPO. 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. Registered office: 3 Clanricarde Gardens, Tunbridge Wells, Kent TN1 1HQ, United Kingdom.© 2021 M.P. Its use in this region dates back more than 5,000 years. Palm Oil: Production, Processing, Characterization and Uses, AOCS Press, 2012 Besides the role of providing a source of vitamin, carotenoids are considered to have anti-carcinogenic properties. Triacylglycerols (Triglycerides) CPO produced in Malaysia in the average will contain about 3.5% FFA, 4.7% diacylglycerols, 0.2% monoacylglycerols, 0.25% moisture and impurities, 1% minor components and balance 90.35% of triacylglycerols. They may occur in the free form, or the hydroxyl group may be esterified by a fatty acid such as linoleic acid, yielding a wax-like arrangement. Although most mills have treatment areas, leaks of effluent can have significant negative impacts on water quality. The extracted oil is known as crude palm oil (CPO). It is therefore essential to minimise bruising or damaging of the fresh fruit before it reaches the mill, where the enzyme, together with any microbial lipases, is inactivated by sterilisation. Phosphatides, as the principal constituent of gums in the crude oil, severely interfere with the efficiency of subsequent process steps if allowed to remain. These are either absorbed onto the bleaching earths or destroyed during thermal treatment. This feature is used to improve the mouth feel (rapid melting) in the following formula: 2. Isomers are defined as compounds with the same molecular formula but different molecular structure. 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. In palm oil sterols, sitosterol (60%), campesterol (13%) and stigmasterol (24%) are the major constituents while a minor amount of cholesterol (3%) is present. McCance and Widdowson's The Composition of Fooods Seventh Summary edition. 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. Phytosterols are important structural components of plant membranes. The major components of interest are the carotenes, tocopherols, tocotrienols, sterols and squalene. 5. 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. α-Carotene and β-carotene are also demonstrated for their provitamin A activity, with β-carotene being the most potential provitamin carotenoids. It May Have Health Benefits. Palm oil is also high in vitamin K and dietary magnesi… 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. The Stationery Office. NOTE – Fatty Acid Nomenclature Hydrolysis can take place in the pre-harvest and post-harvest handling and storage, during oil extraction, crude oil storage, and shipping. Phosphatides darkens the colour of an oil if they become broken down by heat; and can lead to impaired flavour stability. 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. Vitamin A is necessary for vision, growth, cellular differentiation, morphogenesis, and several other cellular and physiologic functions. Palm Oil Development (1990) No 12, 25-27 (http://palmoilis.mpob.gov.my/publications/POD/pod12-4.pdf)Abbreviations: FFA = free fatty acids, ND = not detected, M.P. Alkyl group refers to the carbon-hydrogen chain of the fatty acids. This chart shows fat composition in different Cooking Oils. IUPAC Compendium of Chemical Terminology (2nd ed.). 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. During refining, the bleaching and steam deodorisation processes partially remove some of these valuable components. The Stationery Office. Meanwhile, Iceland has said, ‘By the end of 2018, 100 per cent of our own brand food will contain no palm oil. Palm Olein 1.0 39.8 42.5 11.2 21.6 8.8 C14:O = mysterine acid C16:O palmitic acid C18:O = stearic acid C18:I oleic acid Data for palm kernel oil taken from the Canadian Food Composition Data Base. Crude palm olein has a higher content of tocopherols and tocotrienols. Inorganic phosphate is observed to increase with the content of free fatty acid and pro-oxidant metals, especially in poor quality oils. 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. It is sometimes referred to as red palm oil because of its reddish-orange color. Palm oil mill effluent is a highly polluting material and much research has been dedicated to means of alleviating its threat to the environment. These are named according to the fatty acid or acids they contain. Registered in England No. 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. Just as Van Duijn had discovered at Unilever, the composition of palm oil and palm kernel oil made them the perfect substitute. Both glycolipids and phospholipids are almost completely removed in refining processes; therefore, their content in commercial palm oil is very low. 12c – Since this fatty acids has 2 double bond, the 2nd double bond is indicated on In the case of oils & fats, the carboxylic acids consist of fatty. Ubiquinone is another interesting and valuable minor component present in palm oil. Effect of carbon chain length and unsaturation on melting points of fatty acids. Fatty Acid Composition of PO and PKO Products. An unsaturated fatty acid with a double bond can have two possible configurations, either cis or trans, depending on the 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. ( Log Out / This has important consequences for the oxidative stability of these two fractions. 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. Nutrient Composition. An article on Ethical Consumer stated that the best supermarkets for not using palm oil, or that only used sustainable or organic palm oil, are Marks & Spencer, Sainsbury’s and Waitrose. 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. Studies have shown that a majority of the pesticides applied eventually reach the soil surface, where they gradually spread, translocate to other environments, or eventually degrade. 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). relative positions of the alkyl groups. Carotenes and tocopherols are antioxidants and stabilise the oil against oxidation. Coconut oil (or coconut butter) is a plant oil derived from the kernels, meat, and milk of the coconut palm and fruit. Both are high in saturated fatty acids, about 50% resp 80%. The amounts retained in the refined oils depend on the conditions of refining. 2. (tocopherol equivalents/100g) The major components are α-carotene and β-carotene. This is a result of mainly milling practice. An example is C18:3 cis configuration has a much lower melting point than C18:3 trans configuration. 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. Change ), You are commenting using your Google account. Balanced composition. Frying Oil; 31. Palm-oil mill effluent is a colloidal suspension of water, oil, grease, and solids: it is fairly acidic (pH 4–5) and is typically discharged hot (80–90 °C) (Ahmad et al., 2005). Unsaturated fatty acids are further divided into those that contain one (monounsaturated) or two or more (polyunsaturated) double bond linkages. This composition results in an edible oil that is suitable for use in a variety of food applications. The first stage is a partial hydrolysis, the products being FFA and diglycerides (glycerol with two fatty acids attached). Palm oil like all natural fats and oils comprises mainly triacylglycerols, mono and diacylglycerols. Products that don’t contain palm oil . Where all of the linkages consist of single bonds they are called saturated but if they contain a double bond linkage they are referred to as unsaturated. FATTY ACID COMPOSITION OF PALM OIL AND FRACTIONS Palm Oil Palm Ole ne Palm Stearine 20% Fatty Acid C14:o C16:o C18:o C18:1 C18:2 C18:3 Iodine Value Melting Pt. One of the main parameters influencing the characteristics of fats and oils is the degree of unsaturation of their fatty acids. Compare Canola to Palm oil by vitamins and minerals using the only readable nutrition comparison tool. Compare Palm oil to Vegetable oil by vitamins and minerals using the only readable nutrition comparison tool. 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). It contains 40% oleic acid (monounsaturated fatty acid), 10% linoleic acid (polyunsaturated fatty acid), 45% palmitic acid and 5% stearic acid (saturated fatty acid). Where Ra, Rb, Rc represents the hydrocarbon chain in a fatty acid molecule. Accessed 16 Dec 2019 (https://www.gov.uk/government/publications/composition-of-foods-integrated-dataset-cofid)Finglas PM, Roe MA, Pinchen HM, Berry R, Church SM, Dodhia KK, Farron Wilson M, Swan G. (2015). Data for palm kernel oil taken from the Canadian Food Composition Data Base. Pesticides are used to increase agriculture production throughout the world.
