Virgin coconut oil (VCO) is a processed coconut product that contains high acid which proved to have a health beneficial effect. Fermentation is one of the means to produce VCO. Factors that affect fermentation can be optimized to increase VCO recovery. The objective of the present study was to determine factors that significantly affecting VCO recovery using Plackett-Burman design (PBD), optimization of a fermentation process using Response Surface Methodology-Central Composite Design (RSM-CCD), and determine characteristics of a product. The experiment was performed by growing Neurospora and , isolation, and activity determination of from papaya sap. Nine factors were screened using PBD and the three most significant factors were further optimized using RSM-CCD. The optimum condition was applied to produce VCO and the product was characterized for its properties and fatty acid content. The results indicate that activity, incubation temperature, and pH were the most significant factors that affect VCO recovery. Further investigation using RSM-CCD indicates that optimum condition for VCO production was 1042.4 U, 46.4°C, and 5.07 for activity, incubation temperature, and pH, respectively. The recovery of VCO was 45.06 ± 0.42% and the properties of VCO comply to APCC quality standard of coconut oil requirement with 56.7% acid content.

Virgin coconut oil (VCO) is pure coconut oil with low free fatty acid content and high lauric acid content. VCO has been produced in many home industries where the yield obtained is still very small. So, the researchers tried to find a more efficient production process so that they could obtain high process yields. Researchers made VCO using the aeration method with a diffuser type aerator. The experimental variables were air flow rate (L / min): 0.6; 1.8; 4.0; 4,5 and the duration of the aeration process (hours): 2; 3; 4; 5, by using coconut milk from 1 kg of grated coconut in 1 liter of water, the maximum yield is 33.5% at an air flow rate of 4.0 L / min with an aeration time of 4 hours. The quality of VCO obtained were: water content of 0.02%; iodine number 5,54%; peroxidation number 1.36 g.iod / 100 g; 0.19% free fatty acids; saturated fatty acid content of 93.71% and unsaturated fatty acid 6.24% and the color is very clear. The quality test results obtained are in accordance with the quality standards required by SNI 7381-2008.

Fatty acid content from virgin coconut oil (VCO) is a medium-chain triglyceride (MCT) group. MCT is stable at very low and high temperatures, and the color does not turn black due to the addition of heat so that it can be developed into beneficial cooking oil for health. Therefore, a study was conducted on the content of fatty acids in VCO after being heated at temperatures of 150, 200, and 250°C for 60 minutes. Analysis of fatty acid content in control VCO(T0), VCO with heating temperatures of 150oC(T1), 200oC(T2), and 250oC(T3) was performed with GCMS QP-2010 Ultra.The results showed that there were differences in levels and types of fatty acids in VCO by treating T0, T1, T2, and T3. At these three temperatures still produce medium-chain saturated fatty acids and trans fatty acids are not produced, so that VCO can be utilized as cooking oil that has better stability and benefits for health.

ABSTRACT Virgin Coconut Oil (VCO) is coconut oil that is processed by controlled heating or can be produced without heating (fermentation) so that it does not change the composition or aracteristics of the oil. The purpose of this study was to determine the effect of fermentation time on the physical and chemical properties of VCO. This research includes two stages. The first stage is producing VCO based on fermentation time with raw materials such as coconut and tempeh yeast. The second stage performs physical and chemical analysis which includes yield, water content, free fatty acid content and density. This study used a Simple Completely Randomized Design with 1 fermentation time factor (L). There are 4 fermentation times used, namely L1 = 24 hours, L2 = 36 hours, L3 = 48 hours, L4 = 60 hours with 4 replications to obtain 16 experimental units. Further test using DMRT. The results showed that all yields were above 16%. Fermentation time significantly affected the yield, water content, free fatty acid content but had no effect on density. The best results were shown in VCO with 48 hours of fermentation time, namely yield of 21,843%, water content of 0,238%, free fatty acid content of 0,149% and density of 0,892 g/ml.

Virgin Coconut Oil (VCO) and olive oil have been widely applied in the field of health. Saturated fatty acid content of VCO dominates the total fatty acid content of about 85%. Olive oil contains a lot of oleic acid, which is one type of unsaturated fatty acid (mono-unsaturated fatty acid). This study aimed to analyze the kidney microanatomy rat (Rattus norvegicus) after supplementation with VCO and olive oil in the feed. This study used 25 rats were divided into five treatment groups, P1 was the control group, P2 was a group with VCO 5 mL / kg feed, P3 was a group with VCO 10 mL / kg of feed, P4 was a group with olive oil 5 mL / kg feed and was a group with olive oil 10 mL / kg of feed. The results of ren weight and diameter rat glomerular analyzed using analysis of variance (ANOVA). Research design used was completely randomized design with five treatments and five replication. Results of studies on weight ren showed no significant difference between treatments P2, P3, P4 and P5 to the control (P1). The results of the glomerular diameter  shows there is significantly difference between the diameter of the glomerulous treatment P2 and P3 with control (P1), while in treatment P4 and P5 are not significantly different from the control so that it can be concluded that the administration of the VCO and olive oil at various concentrations do not give rise to different responses to weight ren. Olive oil does not increases glomerular diameter white mice, while VCO at a dose of 5 mL / kg feed and 10 mL / kg of feed can increased glomerular diameter mice. Keywords: ren weight, glomerular diameter, Virgin Coconut Oil (VCO), olive oil.

In the present paper we have determined the fatty acid content of some edible insects of Mexico. A comparative analysis of the insect species studied in this research showed that caproic acid was present in a minimal proportion which ranged between 0.01 for Periplaneta americana (nymphs) and 0.06 (g/100 g, dry basis) for Euschistus strenuus. The highest proportion of caprilic acid (0.09) was found in Tenebrio molitor (adults). Atta sp. had the highest amount of capric acid (0.26). Polistes sp. was found to be rich in lauric acid (0.77) and for myristic acid it had the highest content (5.64). Dactylopius sp. and E. strenuus were rich in palmitic acid (14.89). Euschistus taxcoensis had the highest quantity of palmitoleic acid (12.06). Llaveia axin exhibited the highest quantity of stearic acid (22.75). Polistes sp. was found to be rich in oleic acid (38.28). The highest quantity of linoleic acid was observed in T. molitor (larvae) (10.89), and in L. axin the highest content of linolenic acid (7.82) was obtained. A comparison between the species under the present investigation revealed that, in general, the insects are poor in caproic, caprilic, capric, lauric, myristic, palmitoleic and linolenic acids, because the quantities were either minimal or could not be detected at all. They had moderate quantities of stearic, palmitic and linoleic acids and had high quantities of oleic acid. Finally it was concluded that although a particular insect species is unable to fulfil the total fatty acid need for a human, if consumed in combination they could definitely be able to supply a good amount of this highly valued nutrient.
