This study investigated quality characteristics and sensory properties of gluten-free bread using teff flour and various gums. The five samples used in this study were control (wheat flour), T (teff flour), TG (teff flour, guar gum), TX (teff flour, xanthan gum), and TGX (teff flour, guar gum, xanthan gum). Baking loss, moisture content, pH, salinity, brix, dough expansion, color value, texture property, and sensory property were measured for each sample. As a result, pH was the highest in TX at 6.11 and the lowest in the control at 5.77. Salinity was the highest in the control at 0.80% and lowest in TG at 0.04%. Brix was the lowest in TX at 1.10 °Bx. While moisture content was the highest in the control at 43.58%, gluten-free breads using teff flour had no significant difference (p<0.05). Baking loss rate of bread was no significant difference among samples (p<0.05). Dough expansion rate by fermentation was the highest in the control at 108.89% and the lowest in T at 17.84%. L-value of crust had no significant difference (p<0.05). For L-value of crumb, the control was the highest at 64.34 and T was the lowest at 33.84. In texture properties analysis, hardness was the highest in TGX at 16.00 N and the lowest in the control at 2.87 N. There was no significant difference in springiness (p<0.05). Chewiness was the highest in TX and TGX. The result of sensory properties was that while there were no significant differences in color, salty taste, flavor, and overall acceptability, there was a significant difference in softness and sweetness (p<0.05). These results showed that use of teff flour and gums rather than using only teff flour for bread manufacturing can improve quality characteristics in dough expansion and texture properties. It is considered that xanthan gum or guar gum are appropriate on bread using teff for quality characteristics.
