The invention belongs to the field of foods and in particular relates to an infant molar rod biscuit containing soybean dietary fibers and a production method thereof. The infant biscuit disclosed by the invention contains soybean dietary fibers and also contains flour, white granulated sugar, eggs, grease, starch, whole milk powder, soy isolate protein, sodium bicarbonate, water and other raw materials, wherein the content of the soybean dietary fibers accounts for 2.5 to 9.3 percent of the weight of the biscuit. According to the invention, the soybean dietary fibers added into the formula have the characteristics of high protein and high fiber, the protein content of quality is improved, soybean protein and wheat protein can be well combined, and formation and structure of gluten can be improved, so that the product is higher in hardness. The soybean dietary fibers have good water absorption properties and can maintain 7-8 times of water, the viscosity of the product is improved, and the measured water absorption amount is less than 10 percent. Therefore, a quality surface layer is wetted and softened to absorb water, and the aims of guaranteeing long-term sucking of the infant and improving the tooth grinding and oral cavity practicing skills are achieved.
