The effect of mechanical kneading and Absit preparation on tefinjera quality

The present study was to investigate the effect of mechanical kneading and ‘absit’ preparation difference on tef injera (the common and staple Ethiopian foods) quality. Standard methods were adopted to determine the starch fraction, total phenol, flavonoid, phytate and tannins. Sensory injera quality was assessed using 9-point-hedonic scale. Change in kneading conditions (time/speed) did not significantly affected the free...
