AbstractEssential oils play a prominent role as flavouring agents and fragrances in the food and perfume industries. Carvacrol is a major component of various essential oils, such as oregano and thyme oils, and is responsible for their antimicrobial activity. Lauric acid is a medium-chain fatty acid (MCFA) with a high antibacterial potential. Both carvacrol and MCFAs have been used empirically as antimicrobial agents. Here, we tested the inhibitory properties of carvacrol and coconut (Cocos nuciferaL.) oil containing a high percentage of MCFAs against 5 harmful bacterial pathogens:Escherichia coli, SalmonellaEnteritidis,Staphylococcus aureus, Listeria monocytogenes, andEnterococcus cecorum. Gas chromatography (GC-FID) analysis of coconut oil showed a high concentration of lauric acid (41%). Microdilution antimicrobial assays showed that the combination of carvacrol and coconut oil had a stronger antibacterial effect against all tested bacteria than both agents separately. We conclude that carvacrol could significantly improve the antibacterial effect of coconut oil.

Today, the need for human care and beauty is increasing. The use of personal care products, especially those from nature, has been given special attention by consumers. With diverse features and good effects on the human body, especially the skin, coconut oil is being cared for by many manufacturers. With the aim of diversifying personal care products from coconut oil, this research has initially achieved positive results. Soap saponified as raw soap is considered to have good cleaning effect (better than sodium lauryl sulfate solution (SLS) when diluted to the same concentration). The combination of 10% crude soap and 4% sodium lauryl ether sulfate (SLES) surfactants formulate cleansing products with effective cleansing properties. Ingredients auxiliary cleaners, moisturizing, and softening, antioxidants are added with the appropriate content to improve the disadvantages of raw soap. The personal care products that have been studied have the potential to enter the cosmetic market and attract many consumers.

Fatty Acid Accumulation

Coconut palm (Cocos nucifera L) is an economically important monocot plant grown in tropical and subtropical regions. Coconut oil is stored in a solid endosperm and has 47.48–50.5% fatty acid component as lauric acid (C12:0). Present research showed that acyl-acyl carrier protein thioesterases (FatA/B) and lysophosphatidic acid acyltransferase (LAAPT) are key enzymes determining medium-chain fatty acid accumulation in coconut oil. Among five CnFatB genes, CnFatB3 expressed specifically in endosperm and in vitro experiment showed that this gene made mainly lauric acid (C12:0) and tetradecenoic acid (C14:1). Overexpression of CnFatB3 in Arabidopsis increased the amounts of C12:0 and C14:0 in transgenic plant. CnLPAAT gene that is expressed specifically in coconut endosperm showed a preference for using acyl-CoAs containing C10:0, C12:0, and C14:0 acyl groups as acyl-donor substrates. Coconut and oil palm are closely related species with approximately 50% lauric acid (C12:0) in their endosperm. The two species have a close evolutionary relationship between predominant gene isoforms and high conservation of gene expression bias in the lipid metabolism pathways. Moreover, since no stable transformation system has been constructed in coconut palm, gene function validations have been done in vitro, or genes transformed into a heterologous system.

Virgin coconut oil (VCO) is a superior edible oil extracted from fresh coconut (Cocos nucifera L) kernel using mixed coconut varieties without considering the varietal effect. Therefore, this research focuses on the quality evaluation of VCO extracted from four types of coconut varieties, namely Sri lanka Tall×Tall (TT), a tall variety of Gon Thambili (GT), a tall variety of Ran Thambili (RT) and Philippines tall variety of San Ramon (SR). Mature coconuts from each variety were collected from the Bandirippuwa Estate of the Coconut Research Institute, Sri Lanka to extract VCO by cold press oil extraction method. The extractability of VCO from different varieties was investigated. Moisture, free fatty acid (FFA), fatty acid profile (gas chromatography), peroxide value (PV), color (Lovibond scale), total phenolic substances (Galic acid equivalent), antioxidant capacity (α,α-diphenyl-β-picrylhydrazyl, 0.1mM – DPPH method) and sun protection factor (SPF) of VCO extracted from each variety were analyzed. The experiment was conducted as a completely randomized design with three replicates. Data were analyzed using ANOVA using Tukey’s test by MINITAB 17. Oil extractability (58%-59%), FFA (0.04%-0.12%), color (0.43–0.93) and fatty acid profile of VCO did not show variation among varieties. A higher concentration of total phenolic substances was observed in GT (0.24±0.03mg GAE/100g) while antioxidant capacity (857.19±14.99mg/ml) and SPF (8.99±1.26) was rich in RT.

Soap is a cleanser made by chemical reactions between sodium hydroxide or potassium hydroxide with fatty acids from vegetable oils or animal fats. Soaps can be made by several methods, namely saponification and neutralization methods, in this study carried out by saponification method. In the saponification method there are several problems namely operating conditions which include reaction temperature, stirring speed and stirring time. Therefore, need to do research to determine the best conditions of saponification reaction, namely reaction speed, operating temperature and reaction time using an impeller type multiple pitch blade turbine with research variables reaction temperature 60 oC, 70 oC, and 80 oC, stirring speed 300 rpm,400 rpm and 500 rpm and reaction time of 45minutes, 60 minutes, and 75 minutes. Saponification reaction is carried out by heating coconut oil and inserting 30% NaOH slowly and then stirring with a multiple pitch blade stirrer. The product will be analyzed by testing alkaline levels, moisture content and pH of the soap. The best operating conditions obtained from this study were at a temperature of 70 oC, reaction time of 60 minutes, stirring speed of 400 rpm with a pH value of 9.4 and an alkaline level of 0.073 and a moisture content of 9.8.

Background: Despite the health benefits of coconut oil and its potential for economic development, the availability remain scarce and the cost very high. This is mainly due to poor extraction methods that in turn affect the yield and quality. Aims: To produce coconut oil using different extraction protocols and to compare the quality of the different oil samples. Study Design: The experimental set-up was of a completely randomized design. Place and Duration of Study: Department of Food Science and Technology, Michael Okpara University of Agriculture, Umudike, Nigeria, between August and October 2018. Methodology: Coconut oils produced by natural fermentation, centrifugation, freeze-thaw and solvent extraction protocols were analyzed for physical, chemical, sensory, microbial sensory properties. Results: The solvent extracted oil had the highest oil yield (23.12%) whereas fermentation oil, the lowest (14.19%). The smoke and fire points had 173.75 -176.60°C and 262.45 - 266.65°C respectively. Solvent oil had the highest saponification (261.33 mgKOH/g) and acid values (0.77 mgKOH/g). The oils generally contained more lauric (46.22-48.16%) and myristic (18.03-19.83%) acids. They were also richer in vitamins A (6.22-18.65 ug/g) and E (2.92-4.28 mg/100 g) than D and K. Fermentation oil had the highest microbial count (12.93×02 cfu/ml) whereas solvent oil had the lowest (5.05×02 cfu/ml). Conclusion: The methods used for the coconut oil extraction had significant impact on the quality of the oils. The highest oil yield was the centrifugation oil obtained from Centrifugation Method. The physico-chemical properties and fatty acid compositions of the coconut oils were comparable to international standards. Coconut oil extracted by freezing and thawing was the most preferred in sensory attributes.
