Chemical composition of three cultivars of Brazilian beans

Abstract

Brazil is one of the largest producers and consumers of beans. The grains of beans fill the main dietary recommendations for good health because it provides essential nutrients. In this study, we selected different varieties of beans as IPR88 Uirapuru (Uirapuru), BRS Jalo (Jalo) and BRS Radiante (Cavalo), and compared the chemical composition of raw beans. The samples (10 Kg of each cultivar) were collected in 2012, February (Jalo and Cavalo: latitude -26° 8' 46.78''; longitude -52° 41' 44.78'') and March (Uirapuru: latitude -26° 7' 30.79''; longitude -52° 38' 57.31'') at Pato Branco, Paraná state, Brazil. The physicochemical parameters (lipids, crude protein, fixed mineral residue, humidity, carbohydrates), and minerals content followed the methods described by AOAC. All the analysis was made in triplicate. The mineral composition of the three cultivars studied presented values closed to each other, but IPR88 Uirapuru was distinguished by a greater protein value and a higher amount of calcium and phosphorus. The centesimal composition of the three varieties presented values closed to each other, distinguished BRS Jalo with higher content of fiber. The physical chemical composition showed that they become an excellent raw material for bakery industry and could be used for the development of specific food products.
