| Abstract The aim of this study was to evaluate the effect of freezing and atomization on bioactive compounds in cagaita fruit. The levels of total phenolics, total flavonoids, condensed tannins, vitamin C, β-carotene, the antioxidant potential assessed by DPPH and ABTS, sugar profile, and mineral profile were all evaluated. High levels of total polyphenols (881.95 mg/100 g), total flavonoids (42.93 mg/100 g) and condensed tannins (67.00 mg/100 g) were detected in atomized cagaita pulp. A higher content of vitamin C was found in fresh cagaita pulp (29.75 mg/100 g), compared to frozen pulp, or atomized pulp, which had levels of 24.64 mg/100 g and 20.38 mg/100 g, respectively. Atomized pulp had the highest antioxidant activity as assessed using the ABTS... |

| Abstract Brazilian Savannah native fruits have been investigated as potential sources of antioxidant substances. Cagaita, cerrado cashew and gabiroba were characterized with regard to the ascorbic acid and phenolic contents, antioxidant capacity and flavonoids composition. Gabiroba presented higher contents of ascorbic acid (61.5 mg.100 g–1), total phenolic compounds (1,222.59 mg GAE.100 g–1), and antioxidant capacity (DPPH, FRAP and ORAC assays) than cagaita and cerrado cashew. The correlation coefficients between total ascorbic acid or total phenolic contents and antioxidant capacity were strong and significant (0.970 ≤ r ≤ 0.998). Quercetin derivatives were found in cagaita (1.94 mg.100 g–1) and myricetin derivatives in cerrado cashew (1.2 mg.100 g–1).... |
