Process method for preparing soybean protein vegetarian meat by using double-screw extruder

The invention discloses a process method for preparing soybean protein vegetarian meat by using a double-screw extruder, and belongs to the field of food processing. The process method comprises the following steps: (1) preparing defatted bean flour, (2) preparing soy isolate protein, and (3) mixing the soy isolate protein with the defatted bean flour, adding water to obtain mixed bean flour withthe moisture content of 30%, performing extruding by a double-screw extruder, and performing drying in a hot-blast stove for 3 hours to obtain a vegetarian meat product. The soybean protein vegetarianmeat can well simulate texture characteristics of meat products, and has taste similar to that of meat, so that the purpose of replacing meat products is achieved. 本发明公开一种利用双螺杆挤出机制备大豆蛋白素肉的工艺方法，属于食品加工领域，该方法包括以下步骤：(1)制备脱脂豆粉(2)制备大豆分离蛋白(3)将大豆分离蛋白与脱脂豆粉混合，加水得到水分含量30％的混合豆粉，经双螺杆挤出机挤压后在热风炉中干燥3小时，得到素肉成品。大豆蛋白素肉可以很好的模拟肉制品的质构特征，拥有与肉类相似的口感，以实现替代肉制品的目的。
