Abstract:To develop a kind of biscuit with high-dietary fiber，lotus root and low-gluten flour were used as the main material to optimize the lotus root biscuit processing technology in this experiment.Sugar，butter，baking soda and arrowroot flour were used in the single factor test and orthogonal design test.The result showed that，the optimum formula of biscuit was as follows low-gluten flour 50 g，arrowroot flour 15 g，sugar 15 g，butter 30 g，baking soda 0.3 g，milk powder 5 g and eggs 5 g.The quality influence of the various factors on lotus biscuit was butter＞soda＞arrowroot flour＞sugar.The biscuit manufactured here had a fine structure，crispy taste，complete shape，uniform color and had a special flavour.
