摘要： Coarse cereals have been promoted for their health benefits, and sourdough is used to improve their steamed bread sensory acceptance. However, grains vary in dough physiochemical properties and steamed bread-making performance. This study investigated the effects of yeast and sourdough fermentation on the biochemical, textural, and flavor properties of dough and steamed bread of eight grain types. Results indicated that sourdough dough had a lower pH and higher total titrable acidity compared with yeast group. The texture of sourdough-steamed bread was significantly improved with reduced hardness and enhanced springiness. Microstructure revealed that sourdough resulted in starch surface corrosion and less amylopectin recrystallization. Aldehydes, alcohols, and esters are more dominant in sourdough group than yeast group. Foxtail millet and sorghum steamed breads exhibited the highest performances in texture, flavor, and sensory evaluation. This could provide a theoretical basis for producing coarse cereal products with desirable quality.
