The invention discloses probiotic fermented germinated acid soybean biscuits and a production process thereof. The probiotic fermented germinated acid soybean biscuits consist of the following components in part by weight: 1.5 to 3 parts of germinated acid soybean dregs, 2.5 to 5 parts of flour, 1 to 1.5 parts of sugar, 1.5 to 3 parts of fermentation liquor, 1 to 1.5 parts of water, 0.5 to 1 partof edible oil, 0.25 to 0.5 part of egg liquid, 0.2 to 0.5 part of milk powder, and 0.05 to 0.1 part of baking soda. The production process comprises the following steps of: 1, soaking for germination; 2, fermenting germinated soybean; 3, obtaining germinated acid soybean dregs and fermentation liquor; 4, blending for the germinated acid soybean biscuits; and 5, molding and baking. By the invention, the content of toxic, harmful or anti-nutrient substances in the soybean can be reduced or removed, the protein digestibility is improved, the content of nutrients such as limiting amino acid and vitamins in the soybean is improved, various amino acids are generated through probiotic fermentation, the digestibility, absorption and nutritional value of the probiotic fermented germinated acid soybean biscuits can be improved, and the probiotic fermented germinated acid soybean biscuits have the effects of regulating the intestines, resisting bacteria, preventing diseases, improving immunity and cancer resistance, and slowing cell aging to prolong life, and have moderate sour and sweet taste, rich bean flavor and mellow fermentation aroma.
