We characterized the partially defatted baru flour (PDBF), a byproduct of the extraction of baru oil, and
evaluated its use to produce cookies. Analyzes of composition, total phenolics (TP), total flavonoids (TF),
condensed tannins (CT) and antioxidant activity (AA) were performed. Cookies were prepared with 5
levels of replacement of wheat flour (WF) by PDBF, and compared for antioxidants, texture and acceptance.
PDBF presented more proteins (29.46 g/100 g), lipids (11.84 g/100 g), fibers (38.80 g/100 g), but
fewer carbohydrates (11.57 g/100 g) than WF. PDBF can be labeled as rich in iron, zinc and cooper. TP
(121.34 mg/100 g) were intermediate to levels found in baru almonds and other nuts. TF (85.41 mg/
100 g) was higher than in nuts. CT (64.39 mg/100 g) were close to values known for wines and walnuts
but lower than in other nuts. AA was comparable to many tropical fruits. Hardness and fracturability of
cookies increased starting from 75 g/100 g PDBF. Acceptance of cookies with 25 g/100 g PDBF was
comparable to WF cookies, for some attributes and one group of consumers. Besides the impact on
acceptance, the replacement of WF for PDBF influenced positively on nutritional and antioxidant characteristics
of cookies
