Reduction in phytate levels and HCl-extractability of divalent cations in soybean (Glycine max L.) during soaking and germination

The poor mineral bioavailability due to high phytic acid content in soybean (Glycine max) reduces its nutraceutical significance. Thus, in the present study effect of soaking and germination was investigated in two Indian soybean cultivars, viz., Pusa 9712 and Kalitur for their phytate and total and HCl-extractable iron, zinc and calcium content.

Abstract

The poor mineral bioavailability due to high phytic acid content in soybean (Glycine max) reduces its nutraceutical significance. Thus, in the present study effect of soaking and germination was investigated in two Indian soybean cultivars, viz., Pusa 9712 and Kalitur for their phytate and total and HCl-extractable iron, zinc and calcium content. Soaking for 12 h reduced the phytate content by 10–13 %, while soaking, followed by germination for 72 h reduced the phytate levels further by 46–65 % and increased the extractability of iron, zinc and calcium by 25–36 %. A negative correlation (P < 0.05) was thus observed with the antinutrient phytic acid and the HCl-extractability of iron, zinc and calcium in the sprouted soybean seeds.
