Quick bread leavening process, agents (one or more food-grade chemicals—usually a weak acid and a weak base) are added into the dough during mixing. These agents undergo a chemical reaction to produce carbon dioxide, which increases the baked good's volume and produces a porous structure and lighter texture. Yeast breads often take hours to rise, and the resulting baked good's texture can vary greatly based on external factors such as temperature and humidity. By contrast, breads made with chemical leavening agents are relatively uniform, reliable, and quick. Usually, the resulting baked good is softer and lighter than a traditional yeast bread. Chemical
Tandoor bread infused smoky flavor, which makes it a special delicacy in Southern Asia. Production of tandoor bread is based on seven different phases: survey of current practice, design and installation of a tandoor, and development of standardized procedure for tandoori bread production, development of an evaluation scheme for tandoori breads, development of a reference set of grain and flour samples, investigation of the significance of parameters, and investigation of the relationship between wheat and flour parameters and tandoori bread quality. Aroma, smell, appearance, color, and size, and overall texture are the general characteristics that are optimized by producers of tandoor bread.
