Combination of soaking and cooking was found to be the best method for decreasing the phytic acid content, that is. 48 89±0.152 mg/ IOOg the control and significantly (p< 005) increasing the non-phytate phosphorus and HCI- extractable phosphorus. Some mineral losses were noticed when the legume was subjected to soaking, cooking, and germination but the maximum losses, occurred when the seeds were dehulled. However, HCl-extractability of Ca, P, 2n and Fe improved to a significant extent when the chickpea seeds were soaked, soaked- del7Ulled, cooked and :,prouted which may have been due to decrease in the phytate content followed by processing. Moisture content, crude protein, crude fat, crude fiber and total ash ranges were 5.04-6.88 %, 14.21- 23.86 %, 3.71-6.21%, 1.25-3.97% andI.01- 2.78% respectively. The range of iron, zinc, calcium and phosphorous were 1.34- 4.76, 1.72- 2.94, 69.29 -162.3 7and 20. 75-30.66 mg/ IOOg respectively. Key words.'
