Fifteen commercial soy protein products chosen to represent variations in chemical characteristics were used to fortify wheat flour. While such fortification affected bread characteristics adversely, high-protein soy products, namely, concentrates and isolates, had a more pronounced effect even at a low level (10%) of fortification. Most soy flours, especially full-fat and high-fat products, however, permitted fortification at the 15 to 20% level, and produced breads of acceptable volume, flavor, and overall quality, with resultant substantial increases in protein content and greatly improved amino acid balance.
