The invention discloses a portable type patulin molecular imprinting and silk-screen printing electrochemical transducer, and belongs to the technical field of quick detection. 60-100muL of an electrical conductance liquid containing a to-be-tested sample is dropwise added onto the surface of a patulin molecular imprinting and silk-screen printing electrode, and standing and adsorbing time is 50-210 seconds; then, the patulin molecular imprinting and silk-screen printing electrode is horizontally inserted into a clamping slot of portable type electrochemical detector, a current peak value during scanning is recorded, calculating is performed according to a known standard curve I (muA)=-21.111 log C(mol L<-1>)-125.74 (R2=0.9907) between concentration of patulin and the current peak value; and finally, the tested concentration of patulin in the sample is displayed on an LED screen. The transducer is high in accuracy, is high in stability and is high in repeatability.
