Lab scale hydraulic pressing experiments were conducted to investigate the effect of process parameters on oil recovery from Jatropha kernel. The ranges of pressing parameters investigated were: compression speed, 0.05-2.5. MPa/s; applied pressure, 5-25. MPa; moisture content, 1-6%; pressing temperature, 25-105. °C; pressing time, 1-30. min; shell removal, 0-100%; preheating time, 0-30. min; and particle size, fine, coarse and whole kernel. Chemical analyses such as acid value, phosphorus content, oxidative stability index and water content were carried out to determine the quality of the oil. Moisture content was found to influence oil recovery at any applied pressure and pressure rates. Oil recovery increased to some extent with an increase in temperature or pressing time. The preferred moisture content was found to be about 4% (w.b.). The presence of Jatropha shell and size reduction of the kernel reduce oil recovery.The optimum oil recovery with respect to time of pressing and oil quality was obtained when Jatropha kernel was pressed at 15. MPa, 90. °C, 4% (w.b.) moisture content for 10. min of pressing. The oil recovery obtained at these processing conditions was 86.1%.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Hydraulic press,Jatropha curcas l,Oil quality,Oil recoveries,Process parameters[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Hydraulic press,Jatropha curcas L.,Oil quality,Oil recovery,Oilseed extraction,Process parameters[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors gratefully acknowledge to the Koninklijke Nederlandse Akademie van Wetenschappen , Scientific Programme Indonesia – Netherlands (SPIN-KNAW), The Netherlands for the financial support.
