Bioactive compound is an important component in health care to a majority of the world’s population.  Virgin Coconut (Cocos nucifera) oil is used in Southeast Asia for treating various diseases and is well-known of its rich nutrients.  In this study, supercritical fluid extraction (SFE), an environmental friendly technique was used to extract the interest compounds from crude virgin coconut. The extracted virgin coconut oil is free from organic solvent and safe to be consumed. This is because the solvent used in the extraction process is carbon dioxide which is inert and no solvent residue inside the extracted oil. The layout of the experiment was developed via Statistica 8.0 using the Box-Behnken experimental design model. The oil yield, antioxidant activity and total phenolic content were calculated while the comparison of the experimental results and the statistical data was done using response surface methodology (RSM). Therefore, the optimum conditions of temperature and pressure for the extraction of virgin coconut oil was obtained through the statistical study which is 47°C and 20MPa respectively.

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.

Kelapa (Cocos nucifera) adalah tanaman yang sangat banyak ditemukan di daerah tropis. VCO merupakanminyak kelapa murni yang terbuat dari daging kelapa segar yang diolah dalam suhu rendah atau tanpa pemanasan, sehingga kandungan yang penting seperti Asam Laurat dalam minyak tetap dapat dipertahankan. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan garam dapur dan NaCl terhadap rendemen VCO. Krim santan 400 gram ditambahkan garam dapur dan NaCl masing-masing sebanyak 0 gram, 2 gram, 4 gram dan 6 gram lalu didiamkan selama 3 hari dan 6 hari. VCO yang dihasilkan kemudian dianalisa dengan metode titrasi menggunakan KOH 0,1N untuk mendapatkan bilangan asam yang digunakan untuk mengetahui kualitas VCO yang dihasilkan.Dari penelitian yang telah dilakukan menunjukkan bahwa konsentrasi NaCl dan Garam Dapur yang dapat menghasilkan rendemen optimum yaitu sebanyak 6 gram dengan hasil 49%. Semakin tinggi konsentrasi garam dan semakin lama waktu pendiaman, maka semakin banyak rendemen VCO yang dihasilkan akan tetapi, semakin tinggi juga bilangan asamnya yang menyebabakan rendahnya kualitas dari VCO yang dihasilkan.Kata Kunci: Garam Dapur, NaCl, Penggaraman, VCO.
