Comparison of the vitamin E content of palm oils and other major vegetable oils. 18        – indicates the number of carbon in the molecule, The omega-3 linolenic acid is called alpha-linolenic acid which has three double bonds at 9,12,15 positions, whereas gamma-linolenic acid, omega-6 linolenic acid, 6,9,12 positions. Data for palm kernel oil taken from Canadian Food Composition Data Base (https://food-nutrition.canada.ca/cnf-fce/search-rechercher.do;jsessionid=B71D6F2DDB1BBBFA0516715C001B8095)Abbreviations: FFA = free fatty acids, TE = tocopherol equivalents, Mean values with ranges Composition based on Codex Standards for Fats and Oils from Vegetable Sources (CODEX-STAN 210 - 1999) (http://www.fao.org/3/y2774e/y2774e04.htm)Tocopherol and tocotriencol content based on ABDUL GAPOR Mohd Top. Carotenes preferentially segregate into the more unsaturated olein fraction, leaving little in the stearin fraction. Palm kernel oil, which is semi-solid at room temperature, is more saturated than palm oil and comparable to coconut oil. The palmitic acid content ranges from 49 to 68% and oleic content from 24 to 34% (Sue, 2009).A much harder stearin containing 79% palmitic acid and a tripalmitoylglycerol (PPP) content of 60% is also available. Carotenes and tocopherols are antioxidants and stabilise the oil against oxidation. 8%. High FFA in crude oil will cause greater refining loss. In the case of oils & fats, the carboxylic acids consist of fatty. ( Log Out /  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. Data for palm kernel oil taken from the Canadian Food Composition Data Base. 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. The CoQ10 were report to be about 10–80 ppm in CPO. Effect of carbon chain length and unsaturation on melting points of fatty acids. Both access 16/12/2019. 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. Inorganic phosphate is observed to increase with the content of free fatty acid and pro-oxidant metals, especially in poor quality 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. In terms of fatty acid composition, a typical soft palm stearin might contain almost 50% palmitic acid and 35% oleic acid. 2          – indicates the number of double bonds, The main source of palm oil is the Elaeis guineensis tree, which is native to West and Southwest Africa. 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. 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). 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. Registered in England No. Besides the role of providing a source of vitamin, carotenoids are considered to have anti-carcinogenic properties. 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 Most of the saturated fatty acids occurring in nature have unbranched structures with an even number of carbon atoms.
