Application of  supercritical carbon dioxide (SC-CO2) to vegetable oil extraction became an attractive technique due to its high solubility, short extraction time and simple purification. The method is considered as earth friendly technology due to the absence of chemical usage. Solubility of solute-SC-CO2 is an important data for application of the SC-CO2 extraction. In this work, the equilibrium solubility of the palm kernel oil (PKO) in SC-CO2 has been examined using extraction curve analysis. The examinations were performed at temperature and pressure ranges of  323.15 K to 353.15 K and 20.7 to 34.5 MPa respectively. It was obtained that the experimental solubility were from 0.0160 to 0.0503 g oil/g CO2 depend on the extraction condition. The experimental solubility data was well correlated with a solvent density based model with absolute percent deviation of 0.96. PENENTUAN KELARUTAN MINYAK INTI KELAPA SAWIT DAN PEMODELAN EKSTRAKSI DENGAN KARBON DIOKSIDA SUPERKRITIK. Sehubungan dengan kelarutan yang tinggi, waktu ekstraksi yang pendek dan pemurnian hasil yang mudah, aplikasi karbon dioksida superkritis (SC-CO2) pada ekstraksi minyak nabati menjadi sebuah teknik ekstraksi yang menarik. Karena tanpa penggunaan bahan kimia, metode ekstraksi ini dianggap sebagai teknologi yang ramah lingkungan. Kelarutan zat terlarut pada SC-CO2 merupakan data yang penting dalam aplikasi SC-CO2 pada proses ekstraksi.  Pada penelitian ini,  kelarutan kesetimbangan dari minyak biji sawit (PKO) dalam SC-CO2 telah diuji dengan mengunakan analisa kurva proses ekstraksi. Pengujian kelarutan tersebut dilakukan pada rentang suhu 323,15 K sampai 353,15 K dan rentang tekanan 20,7 MPa sampai 34,5 MPa. Hasil analisa menunjukkan bahwa kelarutan kesetimbangan hasil percobaan  PKO pada SC-CO2 adalah 0.0160 g minyak/g CO2 sampai 0,0503 g minyak/g CO2 tergantung pada kondisi ekstraksi. Data kelarutan kesetimbangan hasil percobaan  telah dikorelasaikan dengan baik menggunakan sebuah model kelarutan yang didasarkan pada densiti pelarut. Pemodelan tersebut mempunyai persen deviasi mutlak  0,96.

Pithecellobium Jiringan (Jack) Prain (P.Jiringan) merupakan salah satu daripada sumber tumbuhtumbuhan yang mengandungi komponen antioksidan. Tujuan kajian ini dijalankan adalah untuk mengkaji kesan-kesan parameter kaedah penyarian bendalir lampau genting dengan menggunkan karbon dioksida sebagai pelarut (SC-CO2) ke atas hasil minyak dan untuk mengukur kebolehlarutan minyak P.Jiringan didalam (SC-CO2) dan mengkorelasi data kebolehlarutan minyak P.Jiringan dengan model Chrastil dan del Valle & Aguilera. Kajian ini telah dijalankan pada suhu antara 40oC sehingga 70oC dan pada tekanan antara 27.58 MPa sehingga 44.82 MPa. Tempoh pengekstrakan adalah 60 minit. Penemuan hasil kajian ini menunjukkan bahawa hasil minyak meningkat dengan peningkatan tekanan dan peningkatan suhu. Pada keadaan suhu malar, kebolehlarutan minyak meningkat dengan peningkatan kepadatan CO2. Analisis keputusan menunjukkan bahawa data keterlarutan minyak P.Jiringan telah berjaya dipadankan dengan model Chrastil. Di samping itu, SC-CO2 memberikan hasil minyak tertinggi berbanding dengan ASE dan proses pengekstrakan Soxhlet. Kata kunci: Kebolehlarutan; Model Chrastil; penyarian bendalir lampau genting; Pithecellobium Jiringan (Jack) Prain Pithecellobium Jiringan (Jack) Prain (P.Jiringan) is one of the medicinal plant sources that consist of antioxidant compounds. The aim of this study was to investigate the effects of supercritical carbon dioxide (SC-CO2) extraction parameters on oil yields and to measure the solubility of P.Jiringan oil in SC-CO2 and correlated the data with Chrastil and del Valle & Aguilera models. The experimental were conducted at temperatures ranging from 40oC to 70oC and pressure from 27.58 MPa to 44.82 MPa. The extraction duration was 60 minutes. The result shows that the oil yields increase as the pressure and temperature increase. The solubility of oil increased as the density of CO2 increased at constant temperature. An analysis of the results show that the solubility experimental data correlated with the Chrastil’s model was successfully matched. In addition, SC-CO2 give the highest oil yields compared to accelerated solvent extraction (ASE) and soxhlet extraction process.

Peanut skin is a waste of peanut industries especially peanut butter industries. Peanut skin contain high antioxidant and high nutritional values. The objective of this study was to optimize the effect of parameters to obtain high extract yield and high antioxidant activity by using supercritical carbon dioxide and co-solvent ethanol. A Box-Behnken design (BBD) was used to optimize the extraction process at the condition temperature (40, 55 and 70 ºC), rate of co-solvent ethanol (2.5, 5, and 7.5 % Vethanol/Vtotal), and extraction pressure (10, 20 and 30 MPa). The extraction time was 3 hours. The optimum condition to obtain yield of extraction and antioxidant activity 22.05 MPa, 62.76 °C and 6.03 %(Vethanol/Vsolvent) with 15.404 % yield extract and 94.040 % antioxidant activity.

A significant quantity of tocochromanols and carotenoids remains in the residual from palm oil production by traditional screw pressing. Supercritical carbon dioxide extraction was used as alternative method with the purpose to recover better these valuable minor compounds. Total oil yield and co-extracted water were investigated in the course of extraction. Tocochromanols and carotenoids were evaluated, not only in the extraction oil, but also in the oil of residual fibre. Modelling of extraction process was also performed for a further up-scaling. The results showed that oil yield up to 90% could be observed within 120 min. Supercritical carbon dioxide (SCCO2) could extract tocochromanols and carotenoids with concentration in the same range of normal commercial processing palm oil, while co-extracted water remained rather low at a level of 2–4%. Moreover, recovery efficiencies of these minor compounds were much higher in case of extraction processed with supercritical carbon dioxide than those with screw pressing method.
