摘要:In this research, we aimed to investigate the production of Turkish type bread better in quality, production cost and its nature by using modified Liquid ferment system. So, the standardization and mechanization of this method was studied. As a natural nitrogen source, wheat germ, active soy flour and high yield wheat flour (type 850) were used instead of yeast food (DAHP + MgSO4). In the both production sizes, with 1 liter at lab, 1000 liter at commercial size fermenter, the liquid ferment breads produced by 1 % yeast inoculations, gave similar results to the control breads produced with 3 % compressed yeast by the direct method, being superior in crumb properties than that of the control. As natural nitrogen source, instead of yeast food (DAHP + MgSO4), 5 % wheat germ or active soy flour were substituted in ferment flour especially at laboratory case, the results were similar to the bread quality produced by yeast food addition. Wheat germ addition gave higher volume and symmetry with better crumb texture and brightness, while soy flour addition shows more volume and yield with whiter crumb. At the commercial condition, the performance was decreased in bread volume and this could be removed by the yeast nutrients additions in addition to wheat germ or active soy flour substitutions.
