  • To investigate the effect of sourdough on the characteristics of quality of barley bread, sourdough starter with Lactobacillus plantarum, Lactobacillus sanfrancisco and Enterococcus sp. were added to baking after 48 hours incubation at $37^{\circ}C$. 1. The pH of bread using Lactobacillus sanfrancisco starter was the lowest among tested starters. while the titratable acidity(TTA) of the strain was the highest, followed by Enterococcus sp.. 2. In bread, moisture contents of control were 38%. It was decreased during 6 days. The moisture contents of bread using Lactobacillus sanfrancisco starter were the highest among tested starters, followed by Enterococcus sp.. 3. Oneset temperature$(T_o)$, peak temperature$(T_p)$ and enthalphy $({\Delta}H)$ were increased during storage of 6 days. The enthalphy of bread using Lactobacillus sanfrancisco starter was the lowest among tested starters, followed by Enterococcus sp..
