The objective of the present study was to investigate the ability of albumin (which has a high capacity for thermal coagulation among dietary proteins) to improve gas cell stability and increase the leavening ability of the bread by preventing the breakdown and merging of gas cells formed by soy globulin during baking. Three types of albumin with different thermal denaturation temperatures were used: ovalbumin, bovine serum albumin, and lactalbumin. The effect of albumin addition on the quality of gluten-free rice flour bread made with soymilk also was determined.
