Abstract
Five improved varieties of Glycine max (TGX 1987-62F, TGX 1485-1D, TGX 1448-2E, TGX 1987-10F and TGX 1835-10E) consumed in Samaru community, Zaria-Nigeria were analyzed for their proximate composition and mineral contents using standard methods. The results show that TGX 1835-10E has significantly (p<0.05) higher protein compared to the other varieties. Carbohydrates and ash contents did not differ significantly (p>0.05) between the varieties. The lipid and crude fiber content were significantly (p<0.05) high in TGX 1987-62F and TGX 1448-2E varieties respectively. Moisture content was significantly (p<0.05) high in TGX 1448-2E and TGX 1485-1D varieties. The mineral analysis showed no significant (p>0.05) difference in the Copper (Cu) content of all the varieties. Potassium (K) and Iron (Fe) contents were significantly high in TGX 1485-1D variety while Calcium (Ca), Magnesium (Mg) and Zinc (Zn) contents were significantly (p<0.05) high in TGX 1987-62F, TGX 1835-10E and TGX 1987-10F, respectively. The results show that none of the test varieties is outstandingly different.
