Washington, DC: U.S. Patent and Trademark Office; 1990. The third phase is most critical phase in the destabilization of coconut milk, coalescence in this stage the interfacial areas is ruptured and reduce that help to joined oil globules together.12 This method appears more desirable due to elimination of solvent and refining, bleaching and deodorizing process, which reportedly may lower the investment cost and energy requirements, thus more environmentally friendly than the solvent extraction. Hot extraction processes has been provide better yield than cold extraction processes. An expeller coconut extraction method uses a mechanized cylindrical barrel to create a pulverized version of coconut meat known as coconut cake. This process helps to breakdown the constituents of the meat to prepare the meat for oil extraction. However, the main disadvantages of fermentation based wet process are time consuming (24-48 h) and poor quality of oil characterized by yellow in color and fermented odour, which can mask the characteristic coconut flavor of the oil due to the presence of unwanted microorganisms and uncontrolled conditions. Coconut oil is a rich source of lauric acid (saturated fat) vitamin E, vitamin K, and iron. Industrial oil processing for the edible oil generally involves the solvent extraction step which may or may not be preceded by pressing. Pour in enough hot water to completely cover the coconut with an extra 1 inch (2.5 cm) or so of water on top. ©2017 Agarwal, et al .

The emulsion was centrifuged and the separated cream was heated at 92°C to obtain oil. The results showed that the yield of VCO was 13.53% at 12000 rpm, at 120 minutes.1 The highest yield of VCO was 13.80% at centrifugation temperature of 40°C. Heated coconut is placed into the barrel where a rotating metal rod is used to crush the coconut. The copra can be obtained by separating the coconut meat from the whole coconut shell followed by sundrying and smoke drying for about 6 to 8 days. Copra is the processed, dried kernel of coconut utilized in the extraction of coconut oil. Olive oil extraction is the process of extracting the oil present in olive drupes, known as olive oil.Olive oil is produced in the mesocarp cells, and stored in a particular type of vacuole called a lipo vacuole, i.e., every cell contains a tiny olive oil droplet. MOJ Food Process Technol. A portion of the oil extracted from copra is lost to the process of extraction. One method of extracting coconut oil is the expeller technique, in which the dried copra passes through a special screw press that compresses the coconut copra, squeezing about 75 percent of the oil from the coconut meat. proposes draft amendments related to Fats, Oils and Fat Emulsions; 2016. In the first stage cream is separated by the action of gravitational force resulting in two phases, the top phase with the creamy layer and the down phase with aqueous layer. During the RBD process, heat is applied to deodorization, which is carried out at high temperatures between 204-245°C. Dry processing requires the meat to be extracted from the shell and dried using fire, sunlight, or kilns to create copra.The copra is pressed or dissolved with solvents, producing the coconut oil and a high-protein, high-fiber mash.
