  The effect of autoclaving on the functional properties of defatted chickpea flour as a function of NaCl concentration (M) was investigated. The protein solubility of both treated and untreated flour showed minimum solubility at 0.2 M and maximum solubility at 0.4 M. Higher emulsion capacity was observed at 0.6 M and then decreased. Maximum foaming capacity of the flour was obtained at 0.2 M and thereafter started to decrease. Foam stability of the flour was minimum at 0.2M and increased with increase in concentration of NaCl. The Emulsion Capacity (EC) of the flour was higher at 0.6M of NaCl. On either side of this concentration, EC gradually decreased. The emulsifying activity decreased slightly when NaCl was added. For both samples the emulsion stability was significantly decreased by addition of NaCl. Autoclaving had no significant effect on the functional properties of untreated chickpea flour.

  Two pearl millet cultivars namely Gadarif and Gazeera were used in this study. The effect of soaking, debranning, dry heating and germination of the grains before and after fermentation on protein content and digestibility was investigated. The effect of processing treatments on the protein content was fluctuated and varied between the cultivars. For both cultivars germination of the grains increased the protein content and digestibility (except course ground grains). For both cultivars fermentation of the germinated and course ground grains increased the protein content while fermentation of other treated grains fluctuated between the cultivars. The protein digestibility of the treated grains after fermentation was greatly improved. For both cultivars fermentation of the germinated grains gave higher protein digestibility (> 90%) compared to all other treatments.
