Quality Characteristics of Bread Using Sour Dough

Abstract

In this study, we examined the changes in loaf weight, loaf volume and specific volume, moisture content and water absorption, pH and titrable acidity, shape, texture profile and sensory evaluation using sour dough instead of dough conditioner in bread making. The weight and volume of bread tended to increase in the sour dough bread, compared to the control. The pH of bread tended to be lower in the sour dough bread. The control bread had large irregular pores that were fewer in number, while the sour dough bread had small spots and was very dense and even throughout the whole surface. The texture profile of bread such as hardness, cohesiveness, chewiness and brittleness was lower in the sour dough bread. There were no significant differences in the sensory characteristics of the breads, except for the shape of bread. However, the sour dough A bread was better in color, texture, flavor, touch, moistness, taste and overall acceptability, and the sour dough B bread was better in flavor, touch and taste than the control.
