Determination of Physicochemical Properties, Fatty Acid Profile and Storage Stability of Virgin Coconut Oil| Chapter 4 | Current Perspectives in Agriculture and Food Science Vol. 2

 The objective concerning this work was to judge the physicochemical characteristics and storage support of virgin coconut lubricate (VCO) extracted using cold press and new press processes. Virgin coconut lubricate (VCO) was extracted from mature crazy of Cocos nucifera, using the cold and the hot process. Hot process present significantly (P0.05) various. Iodine value was 5.72 g/100 g and 6.09 g/100 g for cold pressed and passionate pressed VCO, individually. Lauric acid was the predominant oily acid in the coconut oil samples, record 49.30% in hot rushed coconut oil and 48.76% in cold rushed coconut lubricate. The melting point was erect to increase while the smoke point decreased considerably (P <0.05) for both cold rushed and hot pressed VCO later three months of storage at range temperature (28±20C). Percentage free greasy acid and peroxide values raised significantly from 0.054% to 0.742% and 1.173 mEq/kg to 2.274mEq/kg, individually, after 3 months of storage at range temperature (28±20C). The overall result accompanied that coconut is a good beginning of vegetable oil, with good consistency quality. More also, skilled isn’t much difference in the physicochemical quality of two together hot press and cold press means of extraction.

Conceptual Design of the Production of Virgin Coconut Oil (VCO) Using Low-Pressure Oil Extraction That Employs Centrifugation Method | Chapter 3 | Challenges and Advances in Chemical Science Vol. 9

Virgin Coconut Oil (VCO) is a product made from fresh coconut that is well-known in the market for its numerous applications. The goal of the study is to look into VCO production technologies that use low-pressure oil extraction and centrifugation, determine the percent recovery by weight of all recovered materials and wastes in the processing of VCO, and develop a conceptual design for VCO production that applies to a village-scale coconut community or farm in San Pablo, Laguna, Philippines. Splitting and shredding coconut meat are part of the raw material preparation process. The oil may be recovered from the dried grated coconut meat with 11 percent moisture content at a low pressure of 460 psi. However, the unrefined coconut oil will take at least two weeks to settle using this approach alone. The centrifugation process can significantly reduce the settling time. Based on the investigation of VCO processing technologies, a conceptual design for the combined method that is applicable to a village-scale setting was developed by applying the shortest drying time for the comminuted coconut meat to reach the desired moisture content in a tray dryer at 29.07 minutes at a drying temperature of 70°C as predicted by the Laplace Transform Model in a tray dryer. Low pressure, 2700 RPM, and 60 minutes of centrifugation can be used to extract oil from dried meat, yielding the purest oil with a yield of 92.84 percent v/v and a recovery of 18.43 percent. The VCO generated is supposed to meet the VCO Standards of the Asian and Pacific Coconut Community (APCC). The mass balance method was used to account for the weight of all recovered materials and wastes in the VCO processing technology.

Determination of Atrazine/Streptozotocin-Induced Oxidative Stress and Mitigating Effect of Virgin Coconut Oil in Male Wistar Rats | Chapter 08 | Current Aspects in Pharmaceutical Research and Development Vol. 7

 The goal of this study is to see if Virgin Coconut Oil (VCO) can help rats recover from atrazine-induced metabolic disruption. Adult male albino wistar rats weighing 180-200g were used in the study. They were randomly assigned to one of two primary experimental groups (The test and recovery groups). In the test group, 35 rats were randomly divided into five sub-groups of seven rats each (n=7) and treated as follows: Subgroup (SG) 1 was the normal control, receiving 10 ml/kg of distilled water, SG 2 received 10 ml/kg of VCO, SG 3 received 123 mg/kg of Atrazine (ATZ), SG 4 was the diabetes control that was left untreated, and SG 5 was the diabetic group that received 10 ml/kg of VCO. The animals in the test group were given medication for two weeks before being slaughtered and blood taken for examination. Thirty-five rats from the recovery group were divided into five sub-groups of seven rats each (n=7) and treated as follows for these two weeks: The control group received 10 ml/kg of distilled water, while SG 2 received 10 ml/kg of VCO and SG 3, 4, and 5 received 123 mg/kg of ATZ. The animals were re-treated for recovery after 2 weeks as follows: SG 1 received 10ml/kg distilled water, SG 2 received 10ml/kg VCO, SG 3 received 123mg/kg ATZ, SG 4 received 10ml/kg VCO, and SG 5 received 10ml/kg of distilled water. The animals were slaughtered after two weeks, and their blood was collected for study. Gluthatione (GSH), Superoxide Dismutase (SOD), and Catalase (CAT) levels were considerably lower (p0.05) in the atrazine and diabetes groups as compared to the normal control. GSH levels in the VCO recovery group were substantially higher (p0.05) than in the ATZ group after recovery. Finally, ATZ poisoning generated oxidative stress, but its withdrawal lowered stress considerably, with a stronger impact after VCO delivery.
