The invention belongs to the technical field of pretreatment of materials. The materials comprise starch materials, oil materials and plant fiber materials. According to the main technical characteristics, a low temperature extrusion-multienzyme synergistic degradation material pretreatment method is provided, a to-be-extruded material added with enzyme preparation and with a certain moisture content is blended before extrusion, the to-be-extruded material is fed into screw extrusion equipment to be subjected to low temperature extrusion process, temperature of an extrusion sleeve is less than or equal to 80 DEG C, material moisture content is less than or equal to 70%, multiple enzyme preparations, comprising one or more of high temperature resistant alpha-amylase, glucose saccharifying enzyme, maltase, pullulanase and protease, are added in the material before extrusion, and substances such as starch and cellulose are always degraded under the synergistic action of the added multiple enzyme preparations in a material extrusion process. Compared with the prior art, the method provided by the invention has the advantages that yield of glucose and maltose converted from starch is improved by 0.5-3%, residual oil rate of oil material meal is reduced to 0.3-1.0%, and soluble substances of the plant fiber materials are increased by 3-30%.
