Some selected functional properties of Tef (Eragostics tef) protein concentrate (ETPC) were examined under different chemical environment (NaCl, CaCO3 NaHCO3 and CH3COOH). The least gelation concentration (LGC) was 6%. Increasing the concentration of NaCl from 0.05 to 1.0 M, lowered the LGC to 2%. It was improved to 4% in saturated NaHCO3 but saturated solution of CaCO3 and CH3COOH in the concentration range of 0.05–1.5 M had no effect on LGC. The ETPC foaming capacity (FC) improved at least by two fold in NaCl within the concentration range of 0.05–0.5 M and in saturated solution of NaHCO3. Saturated solution of CaCO3 improved the FC only slightly while 0.05–1.5 M CH3COOH decreased the FC. The water hydration capacity (WHC) was 185.3% which decreased to 149.3% in NaCl as the solution concentration increased from 0.05 to 1.0 M. WHC in 0.05–1.5 M CH3COOH was in the range of 150.0–163.3%. In saturated solutions of CaCO3 and NaHCO3, WHC were 175 and 148% respectively.
