coconut oil composition

A 1981 study of populations on several Polynesian atolls, where coconut oil was the chief source of calories, reported both groups exhibited positive vascular health. But, little do we know about its composition. Coconut oil is 100% fat, 80-90% of which is saturated fat. The full utilization and conversion of this material into high-value products will not only provide greater returns, but also minimize contamination due to biological and solvent residues. Coconut oil (Figure 8) constitutes the major commercial product of coconut. Coconut oil is the preferred source of octanoic and decanoic acids. Jacqueline B. Marcus MS, RDN, LDN, CNS, FADA, FAND, in Aging, Nutrition and Taste, 2019. Both have high levels of medium-chain saturated acids, especially lauric acid (12:0), hence the term lauric oils. Compared to long chain fatty acids (LCFA) common to virtually all vegetable oils, coconut oil contains about two-thirds medium chain fatty acids (MCFA), are smaller, and permeate cell membranes easily. 4.10, which shows the visual appearance of the coconut meat/water mixture with or without the application of megasonics. The coconut endosperm is removed and dried to produce the dried coconut meat, also known as copra, and subsequently, solvents are applied to maximize oil extractability. When we talk about them, people remember summer. World coconut oil production has been increasing over the past decade mainly because of greater global demand for the important characteristics of coconut oil. Moreover, coconut oil is a rich source of medium chain triglycerides with carbon numbers falling mostly in the C32 to C44 range. Coconut oil is 99% fat, composed mainly of saturated fats (82% of total; table). Coconut oil is a fat consisting of about 90% saturated fat. Figure 4.10. The coconut oil produced was white with a pleasant odor, with a PV < 1 meq/kg and acid values < 0.6 mg KOH/g oil (McCormick, 2012). The two oils have been reviewed by Pantzaris and Yusof Basiron (2002). It is also used in the manufacture of methyl esters, fatty acids and fatty alcohols, which are raw materials for detergents, surfactants, emulsifiers and pesticides. The adhesive composition includes a 2-ethylhexyl ester compound of a fatty acid originated from linseed oil, sunflower oil, soy bean oil, corn oil, peanut oil, cotton seed oil, sesame oil, rape seed oil, olive oil, palm oil, coconut oil, castor oil or the like, as a diluent for a urethane resin adhesive containing a urethane prepolymer, a filler or the like. SFAs in coconut oil increase serum HDL cholesterol more than LDL cholesterol to give a more favorable lipid profile relative to dietary carbohydrates. Coconut oil is a source of many oleo chemicals such as fatty acids, methyl esters, and fatty alcohol. “Red palm oil in its crude … It is synthesized in babies from the lauric acid of mother's milk. This shows that the amount of oil contained in the raw material is Coconut oil is mostly produced by a solvent extraction process. of.Coconut oil is 99% fat, composed mainly of saturated fats (82% of total; table). (1986) and Tano-Debrah & Ohta (1997) have investigated aqueous extraction of coconut oil with added exogenous enzymes (proteases, amylases, polygalacturonases, cellulases, pectinases or combinations of enzymes) achieving oil yields ranging from 12–80% from fresh or dried coconut meat. There is no prior drying (e.g., use of copra), refining or chemical reactions before the oil is extracted from coconut meal by mechanical means (expelling, pressing, heating, washing, settling, filtration, and centrifugation). Laura J. Pham, in Industrial Oil Crops, 2016. S.C. Savva, A. Kafatos, in Encyclopedia of Food and Health, 2016. The copra is crushed into a fine powder and heated to 104–160 °C (Thieme, 1968; Food Market Exchange, 2000). P. Juliano, K. Knoerzer, in Innovative Food Processing Technologies, 2016. The production of coconut oil has generally exceeded that of palmkernel oil, but the latter has increased along with the production of palm oil. Coconut oil is very different from most other cooking oils and contains a unique composition of fatty acids. Coconut oil may not be too rich in micronutrients. Coconut water is the “juice” that flows from a newly cracked coconut. Chemical composition: Among the chief constituents, coconut oil also has: The caustic soda solution used was 27% w/w in water. After heating, the oil is extracted using either an expeller or a hydraulic press. In this article we’ll cover the following: What is a Sore Throat? After VCO extraction, the resulting residual material obtained, termed as virgin coconut meal (VCM), has been used to make different traditional Indian sweets (ladoo & burfi) as well as baked goods (biscuit & cake). You may think badly about fats, but our body needs it. However, in the presence of moisture and lipase, the short chain trigylcerides may undergo hydrolysis, giving rise to soapy flavors. A simplified example of an aqueous-based extraction process is shown in Fig. The table showing the types of fatty acid in it is displayed below. As a consequence they have only low levels of unsaturated C18 acids and low iodine values. In pigs, replacement of standard diet with coconut oil modulates the adipose tissue gene expression and fatty acid composition, with minimal effect on serum lipid profile. Worldwide production of coconut oil amounts to 3.5 million metric tons. Coconut oil is an edible oil obtained from the kernel of harvested mature coconuts of the coconut palm .In recent years this oil has attained superstardom in the health food world. Copra, which is obtained by drying coconuts, is the source of coconut oil. The wet process of coconut oil extraction has been gaining in popularity, and studies have been carried out to compare oils extracted by dry and wet processes (Rajamohan and Nevin, 2009). Lauric acid is known to possess antiviral, antibacterial, and antiprotozoal qualities. Some coconut oil products are referred to as "virgin" coconut oil. Hydrogenated coconut oil is widely used as a spray oil for crackers and serves as a moisture barrier and preserves shelf life. The health benefits attributed to coconut oil are controversial. Coconut oil is used as a cooking fat, hair oil, body oil, and industrial oil. Recent studies have shown that the presence of natural coconut fat in the diet leads to a normalization of body lipids, protects alcohol damage to the liver, and improves the immune system's antiinflammatory response. These medium-chain triglycerides or medium-chain fatty acids have different chemical constituents from other saturated fats. Others are actually importing fresh nuts to satisfy their demand while it has become unprofitable for other countries to produce coconut oil. Standards of coconut oil are included in the Codex standard for named vegetable oils CX-STAN 210–1999 (Codex Alimentarius Commission, 2009). The use of solvents is expensive and carries safety risks and environmental concerns; however, it achieves higher oil yield than the aqueous-based extraction methods. The calories in coconut oil come from fat. Virgin Coconut Oil Composition Since virgin coconut oil came from the fresh coconut meat and didn’t undergo intense heat, its flavor and scent are preserved. Both oils may be subject to fractionation, hydrogenation and interesterification (often in a blend with a conventional C16/18 oil) to extend their range of use. It is mostly composed of lauric acid (C12), a saturated fat that can provide energy as well as contribute to weight gain. Marie Wong, ... Leandro Ravetti, in Green Vegetable Oil Processing, 2014. 4.10B shows the enhancement of oil content in the free oil and emulsified oil layer. It is the oil with a higher content of caprylic fatty acid, up to 10%. Coconut oil and palmkernel oil are similar to one another in their fatty acid composition and differ so much from other commodity oils that they can be considered together. I guess we all know how we can use coconut oil to maximize its benefits. Figure 4.8. Figure 4.9. The clear oil may be further processed to remove undesirable colors, flavors and aromas (Foale, 2003). Coconut oil is a common edible oil in certain countries, and there is a controversy regarding its effects on lipid profiles and cardiovascular disease risk. Coconut oil obtained from the nuts of Cocos nucifera was formulated into creams in order to standardize its use and present it in an elegant form. Coconut oil may also be useful for sautéing aromatics (combinations of herbs, vegetables and sometimes meats that are heated in a fat or oil in the beginning of a dish, such as butter, oil) or coconut milk and vegetables In turn, the aromatics may serve to absorb some of the sweetness of the coconut and imbue the entire dish with its fragrance. Coconut oil composes of more than 85% of saturated fats. A third centrifuge separates the fat from the coconut milk to obtain coconut oil and skimmed coconut milk. Sant’Anna et al. Fig. When compared to copra coconut oil (CCO), marginal differences exist with respect to iodine value, saponification value, refractive index, fatty acid profile, specific gravity, and moisture content. J. Siriphanich, ... S. Tongchitpakdee, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Cocona to Mango, 2011. F. Gunstone, in Modifying Lipids for Use in Food, 2006. Fresh coconut meat was ground to particle sizes ranging from 1–4 mm. Another frequently used method of extraction to obtain high oil yield is double pressing with either a hydraulic press or expellers (Gopala et al., 2010). A temperature range of 40–50°C and a malaxing time of 60 minutes was optimum. Thus, the increase in lipogenesis observed in earlier studies was due to the faulty design of the experiments. The consumption of saturated oil could hasten the onset of cardiac problems, as suggested by certain research studies. They are used extensively both as food and as non-food oils and serve as the major source of C8 (caprylic or octanoic) acid and C10 (capric or decanoic) acid. These short-chain acids are concentrated by distillation of the hydrolyzed oils. 2). Not only will coconut oil help root vegetables caramelize, it will lend its essence to ordinary white or yellow potatoes, or bring sweet potatoes to a new pinnacle of taste. Monounsaturated fats are 6% of total composition, and polyunsaturated fats are 2% (table). It’s because the majority of saturated fats found in coconut oil are medium-chain triglycerides. As expected of such saturated oils, the content of tocopherols in the crude oils is low (coconut: a range 0–44 and mean of 10 mg/kg of oil, palmkernel: a range of 0–257 and a mean of 34 mg/kg of oil). Monolaurin is antiviral, antibacterial, and antiprotozoal. Dry milling is a conventional method used in the coconut oil extraction industry. So, a tablespoon of coconut oil contains about 120 calories. The sample treated with megasonics had a dense cream layer that was clearly separated from the sediment when compared to the control (without megasonics), where separation was less evident. Other potential outcomes have also been described with use of coconut oil. Coconut “milk” is produced when the “meat” of a coconut is cooked, and then the meat is strained. More recent research has been carried out to optimize the aqueous extraction process for virgin coconut oil from fresh coconut meat. This accounts for 2.5% of world vegetable oil production. Coconut oil is mainly made up of 85% saturated fat. Virgin coconut oil has retained all the nutrients in coconut oil which includes a high content of vitamin E and minerals. This makes up nearly 60 percent of your daily recommended saturated fat intake. Epidemiological studies also support this. By continuing you agree to the use of cookies. This result is supported by the data shown in Fig. Historically, coconut oil has been used in the vegetable oil imitation dairy food sector for many years. Effect of megasonic treatments (10 min) on oil yield: (A) shredded coconut meat:water mixture (1:3 ratio) using 600 or 2 MHz transducers (230 W, 60°C–different letters indicate significant difference (P < 0.05) between average values); and (B) extracted coconut milk treated at 2 MHz (230 W, 45°C–asterisks indicate a significant difference (P < 0.05) by paired comparisons) (Juliano and Augustin, 2015). Of the saturated fatty acids, coconut oil is primarily 44.6% lauric acid, 16.8% myristic acid and 8.2% palmitic acid, although it contains seven different saturated fatty acids in total. Note that each gram of fat is equivalent to 9 calories. Coconut “meat” is the interior of the coconut that is often shredded and sweetened; however, unsweetened varieties may be available. In a 100 gram reference amount Sterols are around 1000 ppm in both oils. McGlone et al. Coconuts and coconut oil may provide a mellow flavor and creamy texture to some formulations and recipes. Coconut oil is extracted from a coconut kernel. For cooking and toiletry purposes, it is commonly used in the form of filtered coconut oil. There was no significant difference in lauric acid content (46.64–48.03%) among VCO samples. 4.1.2 The colour shall be characteristic of coconut oil 4.1.3 Chemical High-frequency standing waves can be applied either to the coconut meat during digestion or to coconut milk. Coconut oil is considered a lauric oil whose fatty acid composition is high in lauric acid (45–50%). It isn’t just a great tasting oil that you can use anywhere. Virgin coconut oil has a deep coconut flavor that may persist after cooking or baking. Nevertheless, aqueous extraction provides the opportunity to fully utilize food and nonfood materials in the coconut toward the production of value-added bioproducts. Because of the unique qualities of lauric acid (C:12) present, coconut oil is widely used in soaps and cosmetic manufacturing industries. Also present in trace amounts are monounsaturated and polyunsaturated fats. The oil contains close to 12 g of saturated fat per tablespoon. This has changed however, as it was noted that countries with high intake of tropical oils had some of the lowest rates of cardiovascular heart disease, and recently, the use of coconut oil has become more popular because of the potential cardiovascular benefits. Yashi Srivastava, ... Gopal K. Sharma, in Therapeutic, Probiotic, and Unconventional Foods, 2018. Ther Recently, it has been shown that replacing high-PUFA vegetable oils by 75% with coconut oil in the diet of broilers is associated with a reduced fat deposition and increases lipoprotein lipase, hepatic lipase, and total lipase activities, thus affecting favorably lipid profile. It now exceeds that of coconut oil and is likely to continue to do so. Refined coconut oil that has been processed to increase the smoke point may not be as intense in flavor, and it may be useful in deep fat frying and in stir-frying. Sequential filters and/or centrifuges can then be used to obtain the coconut milk. Details of fatty acid and triacylglycerol composition are presented in Table 2.6. It’s because the majority of saturated fats found in coconut oil are medium-chain triglycerides. Positive health benefits are reported to include heart health, promotion of weight loss, support of immune system health, a quick source of energy, healthy skin, and thyroid function. Start with a little cinnamon and … Virgin coconut oil is defined by Codex alimentarius as oil extracted from fresh coconut meat and processed using physical and natural processes (Codex alimentarius, 1999). Chemical Properties. Coconut oil produced by crushing copra is edible and has been consumed in tropical countries for thousands of years. Coconut oil, being a saturated oil, caused concern that adversely affected the prospects of the coconut industry. Ketones are derived from the microbiological dissociation of fatty acids. You can shrug off the worry since experts have already claimed that these saturated fats aren’t as harmful as you think. They don’t stay long in our body and contain a lot of beneficial properties. The next steps will include the testing of this system in combination with small-scale centrifugal separators to understand its direct scalability. Coconut oil comes from the nut (fruit) of the coconut palm. The highly resistant nature of coconut oil to oxidative rancidity is attributed to its high concentration of saturated fat and low unsaturated fatty acids. This oil extraction is immediately followed by the separation of cake residue and mucilage by filtering or by settling. Most households keep a jar of coconut oil as it can be beneficial on numerous occasions. It is this lauric acid which gives coconut oil its white cream color in its stable (solid) state. Some formerly high-oil-producing countries have significantly reduced their production of oil because of the higher price that can be obtained for fresh nuts. The two lauric oils differ in that coconut oil contains slightly higher proportions of the C8 and C10 acids while palmkernel oil has higher levels of oleic acid. Coconut oil contains no chole… Reports indicate that monolaurin is capable of destroying lipid-coated viruses such as HIV, herpes, cytomegalovirus, influenza, various pathological bacteria, including Listeria monocytogenes and Helicobactor pylori, and protozoa such as Giardia lamblia. It has a low content of unsaturated fatty acids with a negligible content of both n:6 and n:3 polyunsaturated fatty acids and a low n:6/n:3 ratio (< 4). The temperature of the oil should be kept at 93–102 °C during oil extraction to obtain a high yield and a light color oil. Coconuts. In wet milling, coconut kernel is disintegrated using a colloidal mill and mixed with a small amount of water before being pressed through the expeller. Consider using coconut oil to impart blander-tasting vegetables with more tropical notes, such as green beans or other legumes, or zucchini and other squashes. Coconut oil is unique in its fatty acid composition, containing more than 65% medium-chain fatty acids (MCFAs)—commonly defined as fatty acids with chains of 6 to 12 carbon atoms (C6–C12) (Fig. The oil remains solid at 20 °C, yet melts very sharply and is completely liquid at 30 °C. It’s important in the transportation of oxygen in the body. After oil extraction, the oil is screened and filtered to obtain clear oil (Chavan and Jadhav, 1995; Food Market Exchange, 2000). The body converts lauric acid into monolaurin, which has antiviral, antibacterial, and antiprotozoa properties. Fig. Coconut cream is coconut “milk” with more fat, less water and generally a greater coconut taste. Canned coconut milk (light and nonlight, with and without added emulsifiers) may be the basis of some savory sauces, especially those that are Asian-based. Interestingly, in mice with stress-induced injury, coconut oil was recently shown to improve lipid profile and restore oxidative stress. You can shrug off the worry since experts have already claimed that these saturated fats aren’t as harmful as you think. US consumption has held steady at about 1 billion pounds over the past decade. This mixture was then malaxed with and without Alcalase 2.4L FG (Novozyme) protease enzyme. What are the components of coconut oil that make it so amazing? The chemical composition of coconut oil makes it possible to use in a wide range of edible and non-edible purposes. A study on the commercial virgin coconut oil (VCO) available in the Malaysian and Indonesian market was conducted. Causes of Sore... @2020 CoconutOils.com All rights reserved. Tocopherols are the natural antioxidants present in coconut oil. Copyright © 2021 Elsevier B.V. or its licensors or contributors. The digestibility coefficient of coconut oil is higher (with 91.0% assimilable glycerides) than any other fat, including butter, and so it is digested more rapidly than any other fats. Blends of VCO were found to be stable for up to 12 months of storage in various flexible and rigid packaging systems, at varying temperatures. They are easily digested and sent directly to the liver, where they are converted to energy rather than stored as fat. Coconut oil is predominantly composed of saturated fatty acids (about 94%), with a good percentage (above 62%) of medium-chain fatty acids among them. Coconut oil is also obtained from extraction of coconut kernel (fresh or copra) using wet milling or dry milling. A shorter chain length allows fatty acids to be metabolized without the use of a carnitine transport system. Coconut oil contains a high concentration of lauric acid (about 50%), a fatty acid with a strong affinity for proteins found in the hair. In a 100 gram reference amount, coconut oil supplies 890 Calories. (2003) and Che Man et al. Visit ChemicalBook To find more Coconut oil(8001-31-8) information like chemical properties,Structure,melting point,boiling point,density,molecular formula,molecular weight, physical properties,toxicity information,customs codes. In its natural, unprocessed state, palm oil is dark red in color due to a high content of carotenoids, including β-carotene (a vitamin A precursor that gives carrots their color) and lycopene.
