2.2.2. Chemical analysis
Acidity value (Oleic acid%) in term of mg KOH g1 oil, peroxide value in term of mEqO2 kg1 oil, iodine value in g I2 100 g1 and specification number in term of mg KOH g1 oil sample were determined according to standard methods (AOAC, 2010). TBA number(Thiobarbituric acid) in mg MDA kg1 sample was measured according to IUPAC direct method (IUPAC, 1992).
