The invention relates to a composition for preparing drawing protein, the drawing protein and a preparation method of the drawing protein. The composition for preparing the drawing protein comprises low-temperature defatted bean flour, optionally one or two of protein isolate and vital gluten, the granularity of the low-temperature defatted bean flour is smaller than 50 meshes, and the DSC endothermic enthalpy value at 95-115 DEG C is larger than or equal to 3.60 J/g. The drawing protein is prepared from the low-temperature defatted bean flour, so that the cost of the drawing protein can be greatly reduced, meanwhile, the influence of the quality of raw materials on the drawing protein is solved, and the drawing protein product which can be stably produced is developed. 本发明涉及一种用于制备拉丝蛋白的组合物及拉丝蛋白和其制备方法。所述用于制备拉丝蛋白的组合物包括低温脱脂豆粉，任选地包括分离蛋白、谷朊粉中的一种或两种，所述低温脱脂豆粉的颗粒度小于50目，95℃-115℃DSC吸热焓值≥3.60J/g。本发明采用低温脱脂豆粉制备得到拉丝蛋白，可以大幅降低拉丝蛋白的成本，同时本发明解决原料品质对拉丝蛋白的影响，开发出一种可稳定生产的拉丝蛋白产品。
