Journal of Oleo Science, 67(7), 823-828.1345-89571347-3352https://dx.doi.org/10.5650/jos.ess17281https://hdl.handle.net/20.500.12395/37010In this study, physico-chemical properties of raw and roasted tigernut oils extracted by two different solvents were determined. Peroxide values of raw and roasted tigernut oils extracted by petroleum ether and n-hexane solvents changed between 0.83 and 0.91 meqO(2)/100g to 1.57 and 1.63 meqO(2)/100g, respectively. While oleic acid contents of raw tigernut oils extracted by petroleum ether and n-hexane are determined as 66.83 and 67.47%, oleic acid contents of roasted tigernut oils extracted by petroleum ether and n-hexane were determined as 67.08 and 68.16%, respectively. The highest delta-tocopherol content was found in raw tigernut oil extracted by petroleum ether (54.91 mg/100g), while the lowest level is determined in roasted tigernut oil by n-hexane (50.77 mg/100g). As a result, the fatty acid profiles of roasted tigernut oil extracted by n-hexane were higher compared to results of raw tigernut oils extracted by petroleum ether (p < 0.05).en10.5650/jos.ess17281info:eu-repo/semantics/openAccesstigernutCyperus esculentus L.oilsolvent typesroastingphysico-chemical propertiesfatty acidtocopherolArticle67782382829877229Q3WOS:000437769300004Q3
