Chemical composition and minerals content of leguminous and cereals produced in the Argentinean Northwest

Different varieties of bean (Phaseolus vulgaris), corn (Zea mayz), lentil ( Lens sp), soya (Glicine max) and wheat (Tricticum sp) were analyzed in orde r to obtaining data of chemical composition and content of minerals to cont ribute to the International Food Data System INFOODS in the elaboration of Regional Food Composition Tables and to evaluate the quality of grains. The selected varieties were the ones produce d in the northwestern region of A rgentina. The beans were divided in five groups, according to their statist ical similarity. The pallares variety is the one that presents bigger conte nt of Cu (2,42 mg/100 g), Fe (76,03mg/100g) and Zn (6,08 mg/100g). The samp les of corn were divided in three groups, according to their statistical si milarity. The leales yellow corn has bigger content of Zn (3,16 mg/100g) th at the other varieties of the region. The 8 rayas white corn is the one tha t presents bigger content of Fe (11,48 mg/100 g), while the pisingallo yell ow corn is that of bigger content of Cu (1,21 mg/100g).
