Taking half of the single-grain peanuts as the research object, the in-situ observation combined texture analyzer was used to carry out the extrusion test to study the mechanics-oil output characteristics of the peanuts under conditions of different extrusion distance, extrusion speed, pressure holding time and temperature, and the relevant curve fitting model was established. The results showed that the peak force of peanuts increased with the increase of extrusion distance. The peanut surface was extruded and began to deform, gradually cracks...
