Nutritional and antinutritional attributes of faba bean (Vicia faba L.) germplasms growing in Bihar, India

Eleven germplasms of faba bean seeds from four agroclimatic regions of Bihar, India, have been investigated to estimate their nutritional (soluble protein, free amino acids, starch, reducing and non reducing sugar, total soluble sugar) and antinutritional (total extractable phenol and condensed tannin/proanthocyanidin) parameters. These parameters were found in varying concentration in all genotypes studied. The highest concentration of total extractable phenol and proanthocyanidin (condensed tannin) (2.56 and 1.59 % leucocyanidin equivalents respectively on dry matter basis) were found in Samastipur while the lowest from Patna (0.95 and 0.426 % leucocyanidin equivalent on dry matter basis). The different nutritional parameters were also found to be in variable concentration among different germplasms viz. total soluble protein a parts per thousand aEuro parts per thousand 20-32 %, free amino acids a parts per thousand aEuro parts per thousand 188-348 mg/100 g, starch a parts per thousand aEuro parts per thousand 27-33 %, reducing sugars a parts per thousand aEuro parts per thousand 85-188 mg/100 g, non reducing sugars a parts per thousand aEuro parts per thousand 0.7-1.7 % and total soluble sugars a parts per thousand aEuro parts per thousand 0.8-1.9 %.
