It does not contain any cholesterol. Moisture,Impurities, Unsap (%) 2 Max. Consequently, the improvement of palm oil quality for a higher degree of fatty acid unsaturation is one of the goals of oil palm breeders. Palm kernel oil is an edible plant oil derived from the kernel of the oil palm Elaeis guineensis. [clarification needed] B. C. Shekhar was appointed founder and chairman. Palmitic acid, C16 (44–45%) and oleic acid, C18:1 (39–40%) are the major component acids along with linoleic acid, C18:2 (10–11%) and only a trace amount of linolenic acid, C18:3. Advances in crystalliser designs, cooling programs and filtration technology have enabled a wider range of stearins to be produced. In palm kernel oil, the saturated fatty acid content accounts for almost 90% of the total fatty acids and the remaining 10% of the fatty acids are mono-unsaturated and poly-unsaturated fatty acids. The differences in TAG composition between olein with iodine value not exceeding 60 and those above 60 are detailed in Table 3.3. 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. Palm kernel oil, similarly to coconut oil, is high in saturated fats and is more saturated than palm oil. Acid Value (mg KOH/g) 254-260. Palm oil contains nonglyceridic contents including carotenes, tocopherols, tocotrienols, sterols, and squalene, which diminish after refinement. Your email address will not be published. [13][14], Resembling coconut oil, palm kernel oil is packed with myristic and lauric fatty acids and therefore suitable for the manufacture of soaps, washing powders and personal care products. Hartley, C. W. S. (1988). Further fractionation of the olein produces a more unsaturated fraction, often called super-olein or double fractionated olein. The use of high-pressure membrane filtration has helped to improve the quality of palm mid-fractions. By judging the amount of hydrogenation of the stearin carefully, an almost identical melting behaviour can be obtained, with applications in confectionery and other food uses. Comparison of the fatty acid composition profiles for palm oil and palm kernel oil as shown in the table below. The majority fatty acid found in palm kernel stearin is C12 which can be found in range of 54.8 to 64.0 wt%. Author information: Download Full Issue. This olein can satisfy the cold test in which the oil must remain clear after 5.5 h at 0°C. This oil contains high C50 (POP) TAG (Table 3.6) and is utilised in manufacture of a cocoa butter equivalent. The same oil palm tree therefore produces 2 different types of oil with different properties and fatty acid compositions, but with the same botanical origin. Fatty acid composition of palm oil and palm kernel oil. Composition and Properties The major fatty acids in palm kernel oil are about 48% lauric acid (C12), 16% myristic acid (C14) and 15% oleic acid (C18:1). Oil palm (Elaeis guineensis) produces two oils of major economic importance, commonly referred to as palm oil and palm kernel oil, extracted from the mesocarp and the endosperm, respectively. The ratio of POP/POO influences the crystallisation of palm oil as shown in Table 3.5. Every fat and oil possesses a natural FA distribution among the glycerides, which affects a product’s consistency as either a solid or a liquid. Triacylglycerol (TAG) Composition of Palm Kernel Oil. SSS TAGs provide structure, SSU TAGs provide both structure and lubricity, and the lower-melting unsaturated TAGs provide lubricity only. Another stearin, produced from a second fractionation of the olein, is called palm mid-fraction (Figure 3.2). Palm oil has a balanced fatty acid composition between SFAs (approximately 50%) and unsaturated fatty acids (MUFA 39% and PUFA 10% mostly as LA). The oil can also be stored longer than other vegetable oils. The quality of the oil is excellent, with free fatty acids of the crude oil generally below 2%. Kernel: Palm Kernel Oil (PKO) Basic Facts • Kernel per fruit: 5-8% • Mesocarp per Fruit: 85-92% • Oil per mesocarp: 20-50% • Oil per bunch: 23-25% Depending on customer requirements, they are available as broad cuts or purer fatty acids by simple or fractional distillation. A wide range of fractions with different properties to suit requirements of the food industry is available through dry fractionation. Products of iodine value around 33–35, previously only available through solvent fractionation, can now be produced from dry fractionation processes. The fatty acid compositions of palm oil are shown below. [7] Palm kernel oil is high in lauric acid, which has been shown to raise blood cholesterol levels, both as LDL-C (cholesterol contained in low-density lipoprotein) and HDL-C (cholesterol contained in high-density lipoprotein). The main type of saturated fat found in palm oil is palmitic acid… Palm Kernel Fatty Acid Distillate or commonly known as PKFAD, is a processing residue from crude palm kernel oil (CPKO) refineries with a high amount of free fatty acids. It is also distinguished from other oils by a very high level of palmitic fatty acid (44%). R Tambun, D G Ferani, A Afrina, J A A Tambun, I A A Tarigan. palm oil in deep-fat frying methods has already been established [15]. The kernel oil is characterised by its high level of shorter and medium fatty acid chain lengths (C6–C14). Palm oil had a fatty acid profile including palmitic, linoleic, oleic, and stearic. It should not be confused with the other two edible oils derived from palm fruits: palm oil, extracted from the pulp of the oil palm fruit, and coconut oil, extracted from the kernel of the coconut. Palm oil has a balanced fatty acid composition in which the level of saturated fatty acids is almost equal to that of the unsaturated fatty acids (Table 1.1). 1. Fatty Acid Direct Production from Palm Kernel Oil . However, palm kernel oil has a lower content of short-chain FA (C6:0−C10:0) and a slightly higher oleic (C18:1) acid content than coconut oil. It contains 40% oleic acid (monounsaturated fatty acid), 10% linoleic acid (polyunsaturated fatty acid), 45% palmitic acid and 5% stearic acid (saturated fatty acid). European merchants trading with West Africa occasionally purchased palm oil for use in Europe, but palm kernel oil remained rare outside West Africa. [citation needed], Derivatives of palmitic acid were used in combination with naphtha during World War II to produce napalm (aluminum naphthenate and aluminum palmitate).[15]. Wilfarin fatty acids are derived from both Palm Oil and Palm Kernel Oil and are produced from the splitting of fats at high temperature and pressure.

Longman Scientific and Technical, Harlow, U.K. Ang, Catharina Y. W., KeShun Liu, and Yao-Wen Huang, eds. In addition to POO and PPO, palm stearin also predominantly contains PPP, a completely saturated TAG. These carbon numbers represent the number of carbon atoms in the three acyl chains and exclude the glycerol carbon atoms. Fat Composition Analysis. Palm Oil : Production, Processing, Characterization and Uses, AOCS Press, 2012 (1999). Palm fatty acid distillate or PFAD is one of the many waste and residue raw materials that we have in our portfolio.. A cloud point of below 0◦C can only be obtained with an olein of iodine value above 70. This stearin has a tripalmitoylglycerol (PPP) content of 60% and is used as hard stock for soft margarines and in infant fat formulas. Saturated TAGs such as PPP, MPP and PPS are the seeds of crystallisation. In contrast PO has gradual melting characteristics. Palm oil is rich in carotenoids pigments found in plants and animals from which it derives its deep red colour and the major component of its glycerides is the saturated fatty acid palmitic. [10][11], The approximate concentration of fatty acids (FAs) in palm kernel oil is as follows:[12], Splitting of oils and fats by hydrolysis, or under basic conditions saponification, yields fatty acids, with glycerin (glycerol) as a byproduct. The major fraction of SFA consists of palmitic acid (44%). Palm oil, like all fats, is composed of fatty acids, esterified with glycerol.Palm oil has an especially high concentration of saturated fat, specifically the 16-carbon saturated fatty acid, palmitic acid, to which it gives its name.Monounsaturated oleic acid is also a major constituent of palm oil. Properties of Palm Oil. Its fatty acid breakdown is 50% saturated fatty acids, 40% monounsaturated fatty acids and 10% polyunsaturated fatty acids. The Chemistry of Oils and Fats, CRC Press, 2004 Palm oil has high contents of disaturated (POP and PPO) and monosaturated (POO and OPO) TAGs. 5. Welding technology for good milling practice. We searched for quantitative trait loci (QTL) associated with the palm oil fatty acid composition of mature fruits of the oil palm E. guineensis Jacq. The TAG (triacylglyceride) profile of palm oil has been characterised by carbon-number gas. PKS – Palm Kernel Stearin In contrast, oleins with IV of less than 60 have cloud point of 6–10°C. Thus, in palm stearin, SSS and SSU constitute more than 75% of the total TAG. Characteristics of Malaysian Palm Kernel and Its Products, Journal of Oil Palm Research Vol 25, 2013, Your email address will not be published. Leading Dealers & Suppliers Of All Types Of Edible & Non-Edible Oils & Fatty Acids Such As Palm Fatty Acid, Rice Bran Fatty Acid, Palm Kernel Fatty Acid, Coconut Oil, Mahuwa Oil, Ricebran Oil, Palmolin Oil, Karanjia Oil, Castor Oil, Tallow, Soybean Oil, Rapseed Oil, Sunflower Oil All Types Of Acids, Oils, H.C.O., Imported Soap Noodles, Stearic Acid, Turkey Red Oil (T.R.O.) A much harder stearin is also available with as much as 79% palmitic acid. Palm oil has a balanced fatty acid composition in which the level of saturated fatty acids is almost equal to that of the unsaturated fatty acids. Palm olein remains clear at ambient temperature of 25°C. Palm kernel oil, which is semi-solid at room temperature, is more saturated than palm oil and comparable to coconut oil. 98 Min. Palm oil gradually increases in liquid oil content until it melts at about 36°C. Figure 3.2 shows the products obtained from multiple fractionations of palm oil. PO – Palm Oil Abstract. The TAG of palm oil consists of C46 to C56 molecules in a near normal distribution, the major TAGs being of C50 and C52. Fractions with iodine above 70 and a cloud point of −4◦C are described as top-oleins. Coconut oil is the highest natural source of lauric acid. Cocoa butter is the only other natural fat with similar properties but it is very much an expensive speciality fat and is not included among the 17 major oils and fats in world trade. Palm oil, a semi-solid at ambient temperature (25–30°C), may be fractionated into a liquid fraction (olein) and a more solid fraction (stearin). Oleic and linoleic acids from PKO goes into the liquid fraction (PKL) during fractionation while the more saturated fatty acids (lauric and myristic acids) go to the solid fraction (PKS).
