The variations of fatty acids proportion during storage and between
treatments with and without nitrogen blanket were slight.
Among the unsaturated fatty acids, it was not observed any change
in the proportions of linoleic acid, contrary to the expected from the
greater susceptibility to oxidation brought about in linoleic acid by
the presence of the two double bonds. However, significant
decrease was observed in gadoleic acid at 120 days of BO storage
without nitrogen blanket. This decrease may result in positive
variations in the proportion of the other fatty acids, as observed for
oleic acid. Slight changes in the proportions of unsaturated fatty
acids reported can be related to the presence in the oil of natural
antioxidants from baru almonds
