The invention belongs to the fields of foods and food processing and particularly relates to a soybean filament drawing protein vegetarian ham and a preparation method thereof. The soybean filament drawing protein vegetarian ham is prepared from soybean filament drawing proteins, vegetable oil, konjak particles, modified starch, vital gluten, table salt, white granulated sugar, soy sauce, edible gum, a vegetarian meat essence, glutamine transaminase, a sorghum pigment and ice water through the processes of preparation of the konjak particles, pretreatment of the soybean filament drawing proteins, the raw material mixing and stirring, sausage filling and formation, hot air drying, stewing, freezing and the like. The raw material formula and production process of the soybean filament drawingprotein vegetarian ham are improved and optimized, the soybean filament drawing proteins are preprocessed in the earlier period, and the later-period stirring process is regulated and controlled, sothat the processed vegetarian ham has fine taste, good elasticity, tenacity and chewing feeling and does not have beany flavor, and a section is silky.
