Proximate Analysis¸ Minerals, Tannin and Phytate Content of Some Local and Imported Legume Seeds

Abstract

The present study was designed to determine the nutrient composition of some Local and Imported Legume seeds. Seeds of ten legume crops, namely local and imported faba bean (Vicia faba), field pea (Pisum sativum), chickpea (Cicer arietnum),lupin (Lupinus termis.) and local seeds of cowpea (Vigna unguiculata L.),and common haricot bean (Phaseolus vulgaris) were investigated for determination of proximate composition, minerals, tannin and phytate. The results indicated that the imported lupin seeds contained the highest protein (39%) content, while the lowest was recorded for the local cowpea seeds (17%) content. The ten legumes had high crude fiber content ranging between 5.0% and 19.8%. Ether extract ranged between 0.07% and 9%,a local faba bean have the highest phosphorous content(1.3%),imported lupin was the highest in calcium (0.7%),and local chickpea was the highest in magnesium (0.3%) and sodium range between 0.04% and 0.1%.Regarding micro elements, selenium range was between (0.1and 0.6 ppm) ,zinc range between (0.04 and 0.1 ppm),cooper range between (0.01 and 0.03 ppm). High manganese was found in local chickpea (7.7ppm), and the highest cobalt was found in imported faba bean(1.6ppm) . High phytate was recorded in imported faba bean seeds 1.7% content, and in imported lupin seeds 1.0 % content. The highest tannin was found in local field pea seeds 0.8% and local faba bean seeds 0. 4%.
