Resumo
Aiming to broaden the knowledge about the nutritional content of baru fruits, a tree species
from the Brazilian Savannah, in order to subsidize its economic management, it was determined the chemical
characteristics of baru almonds from different geographical regions. In the state of Goiás eleven sites were
chosen for their abundance of baru trees, and at each site twelve trees in full production were randomly
selected. Approximately sixty fruits were collected and, after selection, twenty fruits per tree were sampled.
The almonds were extracted from the fruits and crushed, constituting a composite sample. Moisture content,
protein, ether extract, minerals and fatty acid profiles were determined and submitted to analysis of variance
and the means were compared by the Tukey test at 5% of probability. The almonds average moisture
contents varied from 2.93 to 5.07g (100g) -1 from 25.16 to 27.69 (100g) -1 for proteins and from 32.42 to 37.36g
(100) -1 for ether extract. The average content of saturated fatty acids varied from 19.93 to 25.74g (100 g) -1 , and
the unsaturated fatty acids varied from 73.47 to 79.19g (100g) -1 . The most common fatty acids were oleic and
linoleic, followed by palmitic, lignoceric, estearic, behenic gadoleic and araquitic. The most common mineral
macronutrients were potassium, phosphorus and sulfur. Among the mineral micronutrients, iron had the
highest concentration.
