The soybean dregs were rich in protein, dietary fiber and other nutrients. Therefore, addition of the bean dregs into flour would improve both the biscuit nutrition and flavor. In this paper, the formula material was tested by single factor and orthogonal experiments comprehensive the analysis of sensory and nutritional components. The optimum formula was flour 80 g, soybean dregs power 20 g, oil 25 g, granulated sugar 15 g, baking soda 1.0 g, ammonium hydrogen carbonate 0.6 g, δ-gluconic acid lactone 1.2 g, salt 0.4 g and appropriate amount of water. The achieved soybean dregs biscuit with high protein and dietary fiber had golden color and crisp, delicate taste. The products also showed moderate sweet taste and stronger soybean flavor.
