The first step in the oil extraction was scooped out all the aril from the
fruit into a large container. Separation of seeds from the wet aril was done manually.
The wet aril was spread on a stainless-steel drying tray. The tray was then placed in
the hot air oven for about 1 hr under 60C until the surface of the aril was no longer
sticky. The seeds were removed. Aril was dried again in drying oven under 60°C
until moisture content was reduced to about 10%. The aril oil was separated by using
a mechanical screw press with a boiler under 60°C. The oil was settled in a centrifuge
decanter and filtered by Buchner funnel. It was transferred to a sealed amber container
and kept in refrigerator.
