PROBLEM TO BE SOLVED: To provide protein-enriched bread and a manufacturing method of soybean protein for use in the application.SOLUTION: A pasted soybean protein which contains 10 to 50 wt.% of soybean protein material is heated and dried to have a water content of 15 wt.% or less by hot blast at 100 to 250°C. The thus prepared insoluble soybean protein material having a water absorption of 150% or less is used in a bread dough to make bread. The baking quality depends on the degree of water absorption of insoluble particles in a bread dough. The better baking quality (no reduction in the volume of bread) is obtained, as the water absorption decreases. Accordingly, the insoluble soybean protein with reduced water absorption also results in excellent baking quality. |
