The Effect of Germination on Chemical Constituents of Broad Beans and Chickpeas Seeds

Abstract

This study was carried out to find out the effect of germination of broad beans and chickpeas seeds for different periods on their antinutritional factors content ( Trypsin inhibitor and Phytic acid ) and the chemical constituents of germination seeds compared with the control samples (ungerminated seeds) . The results indicated asignificant increase (P<0.05) in crude protein content as germination period proceeded.The highest values of 28.0% and 24.0% were reached on the sixth and fourth day for germinated broad beans and chickpeas respectively, The intial values were 25.6% and 23.5% for control samples, respectively.
The content of raffinose,stachyose and verbascose were reduced as germination period proceeded, Stachyose and verbascose were depleted on the fourth and sixth day of germination for broad beans and chickpeas,respectivley, while both raffinose and stachyosewere completely depleted on the fourth day and verbascose on the sixth day of germination for chickpeas,respectively.
Both trypsin inhibitor activity and phytic acid content of germinated seeds were reduced as germination period proceeded.The highest loss of inhibition activity was on the tenth and sixth day for broad beans and chickpeas and amounted to 13.95% and 26.09%, respectively. The drop in phytic acid reached a peck value of 31.6% and 32.0% on the sixth and fourth day for germinated broad beans and chickpeas, respectively.
