Abstract

Crude palm oil (CPO) was extracted from palm mesocarp by use of hot compressed water (HCW). The extraction time was set to 60 mins, the temperature from 393 to 435 K, and the pressure 3, 4, and 5 MPa. The maximum CPO yields 0.5410 ± 0.0046 g-oil/ g-dried mesocarp with free fatty acid (FFA) of 0.8072 ± 0.0764 %. Simultaneous hydrolysis reaction of mesocarp fiber was occured during the extraction process, and glucose and alcohol were also obtained. Thermal characteristic of solid residue was observed at the different temperature through its structural group analysis. The result suggested that a zero waste processes can be developed by use of HCW.
