| Abstract: | Virgin coconut oil has been reported to provide many health benefits such as increasing the fat metabolite, having high antioxidant, being anti-cancer and decreasing the chance of having cardiovascular disease. As a result, the consumption of virgin coconut oil has increased. In the process of virgin coconut oil production, the coconut testa is removed from the coconut kernel and only the kernel is used to extract the oil. This leads to a large amount of coconut testa being discarded as waste. In general, the testa, which has a high oil content, is either used as low-value feed ingredient or simply discarded. Although, in the coconut testa there is oil as a component, this research aimed to study the triglyceride compositions, crystallization and melting behavior and total phenolic content of testa oil in comparison with virgin coconut oil that produced from coconut kernel only (CKO), coconut kernel with testa (VCO) and coconut refined oil (CNO). It was found that the main triglyceride components in CTO were CaCaLa, CaLaLa, LaMO and LaLaM. The content of these triglycerides in CTO were different than in the samples, resulting different crystallization and melting behavior. CTO crystallized and reached equilibrium rapidly and had a melting peak temperature (21.80 °C) lower than other samples. It melted more slowly than the other samples with lower solid fat content at 10-20 °C but higher solid fat content at 25-26 °C. More importantly, its showed phenolic content of 1.52 mg GAE/100g, highest among all samples. Therefore, the utilization of CTO extracted from coconut testa should be encouraged.
