Abstract

Hot compressed water extraction (HCWE) is a promising green alternative for palm oil milling. The kinetic characteristic of HCWE for palm oil and it β-carotene concentration was experimentally investigated in this study at the different temperature and pressure. Semi-batch HCW extractor from 120 to 180 oC and 30 to 50 bar was used to evaluated the process for 60 mins of extraction in 10 mins interval. The results obtain using the HCWE process was compared with other extraction method. The oil extraction achieved the maximum extraction rate within 20 mins of extraction in most of the condition and starting to decrease until 60 mins of extraction time. The extraction rate for β-carotene was achieved the maximum rate in 10 mins and starting to decrease until 30 mins. None of β-carotene concentration had been extracted out from the palm oil mesocarp after 30 mins of extraction in all condition. The oil recovery of using HCWE was relatively low compare with the mechanical screw press, subcritical R134b, supercritical carbon dioxide and hexane extraction due to the oil loses in the oil-water emulsion. However, the β-carotene concentration in extracted oil using HCWE was improved compare with commercial crude palm oil (CPO) and subcritical R134a extraction.
