Resumo
Baru seeds are commonly found in the Brazilian savanna and present potential to be used
by the food industry due to their high content of fat. In this sense, this study aimed to determine
the physicochemical properties, and chemical composition of baru seed oil. The thermal and
oxidative stability, as well as the interfacial properties of the oil were also evaluated. The free
fatty acid, peroxide, moisture, density, viscosity and the refractive index of the oil extracted from
baru seeds were 0.08% oleic acid, 6.69 meq O2 kg–1 of oil, 0.03%, 0.92 g cm–3, 32.9 mPa s and
1.47, respectively. Since linoleic acid (L), oleic acid (O), palmitic acid (P) and linolenic acid (Ln)
are the main fatty acids present in the oil, the most common predominant triacylglycerols in the
oil are POO, POL, OOO, OOL, OLL and LLL. The oil extracted from baru seeds presented good
thermal and oxidative stability. Moreover, the oil contains high contents of total phenolics and
carotenoids. The reduction of oil-water dynamic interfacial tension was promoted by the presence
of small molecules. Therefore, the oil extracted from baru seeds presents promising properties for
processing in the food industry.
