Aco. Santos et al., CHEMICAL-COMPOSITION AND NUTRITIONAL POTENTIAL OF YAM BEAN-SEEDS (PACHYRHIZUS-EROSUS L URBAN), Plant foods for human nutrition, 49(1), 1996, pp. 35-41
Pachyrhizus erosus seeds were analysed for proximate composition, mine
rals, protein fractions, antinutritional factors, and rotenoids. The s
eeds showed a high content of proteins, lipids, Fe and Ca, in comparis
on to other legumes. Glutelins constitute the highest protein fraction
, followed by globulins. Antinutritional substances detected as tannin
s, hemagglutinating activity and trypsin inhibitory activity, were in
low concentrations. Seeds were also processed to obtain a flour which
showed proper characteristics, good in vitro digestibility, significan
t rotenoid reduction level and amino acid composition rich in essentia
l amino acids, except methionine.
