The invention discloses a food detection and extraction device with size-adjustable sealing performance, and relates to the technical field of food detection. The device comprises an outer box body, a detection box, a detection assembly and a stirring mechanism, an air pump is arranged at the top of the outer box body, and air in the outer box body is pumped out through the air pump; the detection box is fixed on the inner bottom surface of the outer box body, the detection box comprises a U-shaped main box body and movable side plates arranged at the two ends in the U-shaped main box body, and the two movable side plates are driven by a detection space adjusting mechanism to move at the same time. By arranging the U-shaped main box body, the movable side plate and the detection space adjusting mechanism, the internal detection space of the detection box can be freely adjusted, the detection box can adapt to detection of samples with different volumes, by arranging the detection assembly and the stirring mechanism, the detection comprehensiveness is better and more accurate, and the problems that an existing food detection and extraction device is poor in sealing performance and poor in detection accuracy are solved. The food is easy to pollute, and the detection accuracy is influenced.
