Extraction of Phytochemical Compounds from Pressed-Palm Fiber Using Water and Pressurize Carbon Dioxide
Sub-critical extraction of palm oil from pressed palm fiber using water and preassured carbon dioxide solvent
was conducted via the dynamic mode to investigate the ability of water and CO2 to extract α-tocopherol, β-
carotene, and phenolic compounds. The yield of palm oil and the solubility of α-tocopherol, β-carotene, and
phenolic compounds were investigated at 120; 140; 160; and 180oC and pressure range from 30–100 bar. The
extracted oil was analysed α-tocopherol, β-carotene, and phenolic compounds content using UV–Vis
spectrophotometry. The results The temperature increase on the process of extracting hydrothermal on the
temperature (120-180oC) increase yield α-tocopherol .The steady to extract α-tocopherol , an acid palmitate
and β-carotene on the temperature 180oc with pressure 10 MPa .From the experiment done get the best result
on the temperature 180oC to pressure 10 MPa with yield α-tocopherol 271,28 mg/g sample (% recovery is
73,06%), yield pamitate acid 2,066 mg/g sample (% recovery is 0,55% ), and yield β-carotene 0,008 mg/g
sample (% recovery is 0,0021 %) as compared to that achieved through conventional palm oil processing
indicates that extraction of α-tocopherol, β-carotene, and phenolic compounds using this methode is viable.
