The coconut is a large seed that grows on tropical palm trees. However, VCO separated from coconut milk with three different maturity stages had a similar fatty acid composition (Patil et al., 2016). Number of times cited according to CrossRef: Development of novel plant-based milk based on chickpea and coconut. The FFA, peroxide, iodine, and saponification values reported for commercial VCO samples were in accordance with the specification guided by Codex standard (2003) for refined coconut oil. Protein powders from milk cake showed higher oil and water absorption capacities. To obtain VCO from the wet extraction process, destabilization of coconut milk emulsion has been implemented via several processes such as physical extraction, fermentation, and enzymatic extraction (Raghavendra & Raghavarao, 2010). Chilling and thawing techniques have been used to destabilize oil‐in‐water emulsion. This environment can promote the growth of microorganisms (Tansakul & Chaisawang, 2006). Water, sodium chloride, isopropanol, acetic acid, and sodium hydroxide soluble fractions are designated as albumin, globulin, prolamin, glutelin‐1, and glutelin‐2 fractions, respectively. Oat milk may have eclipsed all other alts on store shelves, but that doesn't mean that other options aren't worth having in your rotation. Basically, coconut milk is an oil‐in‐water emulsion, stabilized by some proteins existing in the aqueous phase. Sucrose ester had a moderately good capacity to minimize the interfacial tension between the oil‐water interface of coconut milk. VCO, without bile, can easily digest and goes directly to the liver for conversion into energy (DebMandal & Mandal, 2011). Diets rich in VCO decrease WC and increase HDL‐cholesterol concentrations, thus supporting the secondary prevention for CAD patients. High protein content can lead to efficient localization of protein films at the oil–water interphase. Coconut (Cocos nucifera L.) is economically important and generally used in many traditional foods of Pacific and Asian regions (DebMandal & Mandal, 2011). It is a very popular product that is in great demand the world over in the confectionery and allied food industries. The coconut tree is a monocot. VCO is rapidly gaining popularity because of high stability and various health advantages (Carandang, 2008). In coconut milk, cream separates from the aqueous phase within 5 to 10 hr of production (Seow & Gwee, 1997). A hammer can be used on a coconut to create a half coconut , which can be used on an empty vial to gain coconut milk and a coconut shell . Overview Information Coconut is the fruit of the coconut palm. This cavity is filled with liquid. (2016) studied characteristics as well as the quality of VCO as influenced by maturity stages. Maximization of protein functionality as an emulsifier can enhance the coconut milk stability. However, no drastic differences in overall VCO quality were observed. (2017) carried out a comparative study to evaluate the physicochemical properties and emulsion stability of coconut milk obtained from the coconut at three different maturity stages. Learn more. Proteins were extracted using alkaline extraction process from coconut milk press cake using saturated Na3PO4 and the yield of 47% was obtained (Chambal, Bergenståhl, & Dejmek, 2012). VCO or coconut oil consists of medium chain fatty acids (MCFAs), mainly lauric acid. The shells and parings are removed and the white meat is sterilized and milled for extraction of milk. The process resulted in high extraction yields (76.4%) of oil, as compared with a nonenzymatic process, in which the yield was less than 20% (Barrios, Olmos, Noyola, & Lopez, 1990). Neutrase 1.5 MG (0.3%, w/w) and Viscozyme L (0.6%, w/w) at pH of 7, the temperature of 60 °C and total incubation time of 30 min were used to achieve the maximum extraction yield of oil (Sant'Anna, Freitas, & Coelho, 2003). Processing operations, which tend to produce smaller globules, are expected to yield more stable emulsion (Onsaard et al., 2005). Coconut milk is generally extracted from grated coconut meat after pressing or squeezing with or without the addition of water. The coconut globulin contains a high amount of essential amino acids including valine and phenylalanine but has less glutamic acid, lysine, and arginine than the albumin (Kwon et al., 1996). Coconut globulin consist of two major types, named 11S and 7S globulin. Moreover, the maximum yield of VCO could be attained Senphan and Benjakul (2015). We pick the best Indian coconuts, ripe brown and mature. Stability of coconut milk emulsion depended on intrinsic factors, mainly pH and protein content. Desiccated coconut is crisp, snow white in colour and has a sweet, pleasant and fresh taste of the nut. This first layer is thin and gelatinous. Globulin fraction was more competent as an emulsifier in the oil‐in‐water emulsion as compared to albumin. MCT is known to help decrease body fat and fight against some of the unhealthy metabolic changes that happen in conjunction with weight gain. The separation of VCO can be further enhanced by several methods. In this process, clean ground copra is pressed by screw press, wedge press, or hydraulic press to release the coconut oil, which is subsequently subjected to refining processes, namely degumming, bleaching, and deodorizing. In general, centrifugation is used to accelerate this creaming process, in which higher rotation frequencies are allowed to separate the cream effectively. The separated oil can be collected. The differences in maturation stage, fertilizer, climate, starting material, and so on, also result in varying proportion of various proteins in coconut meat (Patil & Benjakul, 2017). (2012) characterized VCO obtained from different methods including chilling, fermentation, fresh‐drying, and enzyme treatment. The coconut 7S globulin is unglycosylated and lack of sulfur‐containing amino acids (Carr, Plumb, Parker, & Lambert, 1990). The oil droplets in coconut milk emulsion are surrounded by a film of interfacial active protein and emulsion stability is depending on these proteins (Dendy & Timmins, 1973). When repulsive forces are dominant, the oil droplets have a tendency to persist as individual entities, thus forming a stable emulsion. Similarly, VCO was obtained from the chilling method by centrifugation of coconut milk at 3600 x g for 10 min and the cream was removed from the upper layer. The effect of consumption of VCO on HDL cholesterol and waist circumference (WC) in coronary artery disease (CAD) patients was studied by Cardoso, Moreira, de Oliveira, Raggio Luiz, and Rosa (2015). The shells and parings are removed and the white meat is sterilized and milled for extraction of milk. (1996) and Sringam (1997). Nevertheless, the fat content of the coconut milk extracted at 55 °C was the highest, while those of coconut milk extracted at 30 °C and 80 °C were not significantly different. The freshly prepared coconut milk appears stable and homogenous. About eight months later, the soft white endocarp becomes hard and dark brown. Those include isoelectric (pI) precipitation, heat coagulation, combined isoelectric precipitation as well as heat coagulation, and co‐precipitation with a calcium salt. Hydrophobic domains or nonpolar side chains of the proteins were able to interact with hydrocarbon chains on fatty acids. Furthermore, protein denaturation was observed in coconut milk when heated at a higher temperature. Coconut milk fat structure affected by homogenizing pressure was investigated by Chiewchan, Phungamngoen, and Siriwattanayothin (2006). After about four months, the husk and shell become thicker. Protective effect of VCO against liver damage in albino rats challenged with the anti‐folate combination, trimethoprim–sulfamethoxazole (TMP–SMX), was studied by Otuechere, Madarikan, Simisola, Bankole, and Osho (2014).

Solubility and emulsification properties of APE increased at pH above and below 3 to 4. The main coconut producing countries are the Philippines, Indonesia, India, Papua New Guinea and the Pacific Islands. of Food Technology, Faculty of Agro‐Industry, Prince of Songkla Univ., Hat Yai, Songkhla, 90112 Thailand. It is then granulated into the various sizes. Coconut Palm Sugar. Enthusiastic go getters who are interested in a fast track career can contact us at careers@palmoindia.in. Distribution of proteins in defatted coconut meal, classified based on solubility, is shown in Table 2. Gravitational separation is mostly related to the slow creaming process of an oil‐in‐water emulsion. Protease efficiency in enhancing extraction yield of oil was found in descending order as follows: alkaline protease > neutral protease > acid protease. The predominant proteins in coconut endosperm or kernel are classified as globulin (salt‐soluble) and albumin (water‐soluble), which account for 40% and 21% of total protein, respectively (Balachandran, Arumughan, & Mathew, 1985; Kwon et al., 1996). First, the husk and shell grow and cavity of embryosac enlarges considerably. Clinical and Experimental Neuroimmunology. The 73.8% of oil recovery with fine quality of oil were gained. Variation in the distribution of amino acids and the proportion of nonpolar and polar amino acids, mainly on the surface of the protein, determine emulsifying property. The combined methods should be developed to enhance destabilization of coconut milk, in which the shorter processing time and lower cost can be achieved to manufacture VCO. Thungkao (1988) also documented that protein contents were not affected by temperatures (30 °C, 55 °C, and 80 °C) used for coconut milk extraction when the grated coconut meat and water ratio of 1:1 was employed. Coconut, a palm with multiple uses and known by the producing communities as the "tree of life", has been supporting the livelihoods of approximately 20 million workers around the globe. Thermal denaturation of coconut proteins influences the surface charge of oil droplets and causes droplets aggregation in coconut milk. The microstructure of sodium caseinate stabilized coconut milk emulsion was not changed by heating (70 °C, 90 °C, or 120 °C) for 1 hr. Because coconut milk comes from the meat of a coconut — not an animal — it’s not a dairy product. No marked change was observed in droplet size of the emulsion heated at a temperature of 70 °C. Because proteins have polar groups, their intra‐ and intermolecular interaction are directly affected by changes in pH of the emulsion. Recently, wet process has become very popular to produce coconut oil or VCO and does not need the refining process. Threonine, cysteine, and methionine seemed to be the limiting amino acids for coconut proteins (Kwon et al., 1996). Moreover, coconut meat is grated, mixed with or without water and pressed to extract the coconut milk (Grisingha, 1991). This results in unstable coconut milk emulsion. The exposure to heat at high temperatures for a long time, results in denaturation and precipitation of proteins in the coconut milk. Creaming is due to differences in density between the two phases, which leads to phase separation (Beydoun, Guang, Chhabra, & Raper, 1998). Flocculation is the aggregation of oil droplets due to weak repulsive forces and strong attractive forces between oil droplets (Verwey, 1947). In this case, the breakdown of emulsion is crucial for the effective recovery of both protein and oil. Effects of sonication (120 W, 20 kHz and 250 W, 20 kHz) on the stability of sunflower oil‐in‐water emulsions prepared by coconut milk protein was studied by Lad and Murthy (2012).
