Fatty acid profiles in the pressed-cakes were determined by gas
chromatography according to the AOAC method number 996.06
(AOAC,2012). For the present analyses, the samples were extracted with ether by Soxhelet extractor.The obtained oil was
stored in Eppendorf tubes,and the air was removed and replaced
with nitrogen. Fatty acid was identified by comparing the retention times to the known standards. The results were expressed as g fatty acid/100 g sample.
