Table 4 presents the results of the esters of fatty acids identified by means of gas chromatography. When analyzing the data, it is evident that the treatments directly interfered in the concentration of the three main fatty acids belonging to the C18 group, with reductions of approximately 1.5% in steriac acid, 4% in linoleic acid and increase of approximately 6% in oleic acid. Fig. 3 depicts the relation between the acidity reduction and increase in concentration of oleic acid according to type of treatment. Production of this acid was favored by the reduction of the two other acids belonging to the same grouย
