Brassica chinensis bean sprout soup material preparation method

The present invention relates to a brassica chinensis bean sprout soup material preparation method, and belongs to the technical field of food preparation. The brassica chinensis bean sprout soup material preparation method comprises: 1) material preparation; 2) steam explosion; 3) mixing; 4) centrifugal drying; 5) drying by baking; and 6) packaging. According to the invention, steam explosion is adopted to complete a material cooking process so as to substantially reduce a boiling time and reduce energy consumption by about 90%; with steam explosion, heat energy of the material can be converted into mechanical energy during the steam explosion process so as to separate lignin and cellulose and dissolve amylopectin, the expansion cooling physical processes is generated along with the steam explosion process, and the temperature is reduced to a room temperature from the before-explosion temperature of 200-250 DEG C, such that the cooling treatment is not required, a lot of time and energy sources are saved, and material processing continuity is achieved.
