By incorporating approximately 1/3 of the soy
ingredient as soy milk powder in this study, textural detriments
were partly circumvented while maintaining high protein
content. This is likely due to the higher ratio of soluble fiber :
insoluble fiber in the soy milk powder compared to defatted soy
flour.In addition, a chewy texture and darker brown color
(imparted by the lye bath), while generally not acceptable in
bread, is regarded as a positive quality in soft pretzels by
consumers.
