effect of reconstitution and na2co3 on tannin content and in vitro protein digestibility of faba bean cultivars. | two faba bean cultivars (317/99/81 and giza/402) obtained from shambat research station in northern sudan, were used for this study. investigation showed that the tannin contents of untreated seeds were 0.077% and 0.067% for cultivars 317/99/81 and giza/402. in vitro protein digestibility values were 80.68% and 81.48% for the two cultivars, respectively. the extractable tannin content of the faba bean cultivars was markedly reduced by imbibing water or na2co3 solution into whole seeds and incuba ... | 1993 | 8378270 |
