Variability in the physicochemical, nutritional and antinutritional attributes of six Mucuna species

The antinutritional factors estimated in the seeds included total polyphenolic substances, protease inhibitor, saponins, phytic acid, l-dopa and flatulence sugars. The concentration of phenolic substances ranged from 4.34% to 7.75%, while the concentration of protease inhibitor, TIA, ranged from 18.5 to 23.1 mg g−1 sample. Saponin concentration ranged from 0.52% to 3.01% while the phytic acid concentration in the seeds was between 1.23% and 2.56%. l-dopa concentration ranged from 3.87% to 7.12%. Out of the three flatulence sugars estimated in the seeds, verbascose showed the highest value.
