The performance of a soy polysaccharide blend in soft wheat products was evaluated; AACC soft white wheat bran was used as a reference fiber source. In Chinese steamed breadmaking, up to 10% soy polysaccharides (wheat flour basis) had less effect than bran on color and surface smoothness but exerted a more detrimental effect on volume and texture. In the cookie-baking test, reduction of cookie diameter and top grain characteristics were more pronounced when up to 15% bran was incorporated. Addition of up to 4% of the two fiber sources to a Japanese sponge cake formulation showed that soy polysaccharides were superior regarding volume,color, and crumb grain. Japanese udon noodles enriched with 8% soy polysaccharides were slightly yellowish and not gritty, whereas 8% bran imparted a brown color and a slightly gritty mouthfeel. The five original soy polysaccharides that constituted the blend were characterized in terms of their analytical and functional properties. They could be ranked according to their color L values. The darkest soy polysaccharide sample differed significantly in particle size distribution from the others. Functional differences among the samples were found in steamed breadmaking and the cookie- baking test.
