2.3.1 Chemical analysis of oils
The fatty acid compositions of CSO and SFO were determined using gas
chromatography.24 The main difference between the
fatty acid composition of used CSO and SFO in this study was the
percentage of LA (15.2% in CSO versus 62.1% in SFO), oleic acid
(14.20% in CSO versus 27.80% in SFO) and ALA (38.4% in CSO versus
0.16% in SFO). The percentage of other fatty acids has been compared in
Table 1.
