BACKGROUND: There are more than 30 peanut cultivars registered in Brazil. However, there is no published data about the content of nutrients and anti-nutrients even in the most commercially important ones. Therefore, our objective was to characterize commercial peanut cultivars harvested in Brazil by determining proximate and fatty acid compositions and contents of selected minerals and phytates, saponins and condensed tannins. RESULTS: Significant variations were found among the cultivars for almost all studied nutrients, except Mg. Granoleico and IAC 505 were identified as high oleic. Results were compared with data from the Brazilian Food Composition Table (TACO) and for this, percentage differences (D%) were calculated. Appreciable D% were found for proteins, lipids, ash, dietary fiber, almost all fatty acids (except 20:0), and almost all studied minerals (except zinc). Moreover, remarkable variations on contents of anti-nutrients were observed. IAC Red Tatu had the highest contents of saponins; IAC OL3 and IAC 886 had the highest amounts of phytates; and IAC 886 had the highest amounts of condensed tannins. CONCLUSION: Results confirm the relevance of differentiating cultivars in the market and in national food composition tables and databases. Furthermore, some of these cultivars may be indicated for new use trends.
