  The study was conducted to evaluate changes during germination in chemical composition, phytic acid, phytase activity and total and extractable minerals of lentil cultivars. Three Sudanese lentil cultivars (Rubatab, Nadi and Selaim) were germinated for 3 and 6 days. The germinated seeds were dried and milled. Proximate composition, phytic acid content, phytase activity and hydrochloric acid (HCl) extractability of minerals were determined. During germination crude fat and fiber increased, whereas nitrogen free extract (NFE) and food energy decreased. Phytic acid content decreased significantly (p≤0.05) with an increase in germination time. Germination resulted in a decrease in total phytate phosphorous with correspondingly marked increase in non-phytate phosphorus. Total and extractible minerals (P, Ca, Fe, Mg, Cu and Zn) were positively correlated with duration of germination except Cu and Zn. Germination for 3 days increased phytase activity significantly (p≤0.05) for all cultivars. Phytase activity of Rubatab cultivar continued to increase up to 6 days of germination, however, for Nadi and Selaim cultivar it slightly decreased. In order to obtain lentil seeds with high phytase activity, low phytic acid and high mineral extractibility, germination process for more than 3 days is recommended.

  Two pearl millet cultivars (Gazira and Gadarif) were processed (grinding, soaking, autoclaving, germinating and debranning). The processed grains were fermented for 12 and 24hrs. Phytic acid, polyphenols and tannin contents were determined. Results obtained showed that phytic acid content was 987.19 and 952.51 mg/100g for Gazira and Gadarif cultivars, respectively. Processing treatments were observed to decrease phytate content significantly (P = 0.05) for both cultivars with a maximum reduction observed when the grains of the cultivars were germinated. Polyphenols and tannin were also decreased significantly after processing of both cultivars. Further reduction in antinutritional factors was obtained when the processed grains were fermented for 12 and 24 hrs. The rate of reduction differs between the cultivars and the processing treatments.
