Abstract

This research was conducted to determine the effects of some factors on oil extraction
from seeds of passion fruit such as: solvent, the ratio of material/solvent, temperature, extration time, etc. The results showed that n-hexane was an appropriate solvent to extract
oil from these seeds. Some proper factors for oil extraction were as follows: material size
(≤ 0.2 mm), twice extraction (1st: 1/6 and 2nd: 1/5), the ratio of material/solvent (v/w =
1/11), at 600C in 8 h (1st time: 5h and 2nd time: 3h). Oil yield obtained 93.4%. The study
also evaluated the quality of the oil obtained and analyzed the fatty acid composition in
the passion fruit oil. The contents of omega 6 and omega 3 fatty acids were 70.8 - 72.7%
and 0.2 - 0.3%, respectively (% dry matter). This is considered to be a good source of
omega 6 and omega 3 fatty acids that can be used in the production of functional foods
and pharmaceuticals.
