Comparative Studies of some Chemical and Micronutrient Contents in three Sprouted Samples of Bambaranut (Vinga subterranean [l] verdc.) Landraces

Abstract

The research was carried out to evaluate the effect of sprouting on chemical and micronutrient contents of Bambaranut (Vigna subterranea [l] verdc.) grown in Kano, Nigeria. Three landraces of Bambaranut (cream, black and zebra) were used for the study. The proximate and mineral contents were analyzed in accordance with the standard methods of analysis. The result of the proximate analysis showed that the moisture and carbohydrate contents reduced significantly (P<0.05) after sprouting while ash, crude protein, crude fat, and crude fiber significantly increased, there was no significant (P<0.05) difference in moisture, crude fiber, and carbohydrate contents between the landraces. The landraces differ in crude protein and fat contents. The results of minerals analysis shows that the landraces differ significantly in Na, Fe, Ca, K, Mg, and Se. However, the amount of Zn, Mn did not significantly differ between the landraces irrespective of sprouting or not. All the three landraces did not differ (P<0.05) in Cu contents. Sprouting leads to decrease in Na, Fe, K, Zn, Mg and Se and increase in Ca and Mn. This study showed that sprouting improves the nutritional quality of Bambaranut irrespective of the landrace.
