Abstract: The invention discloses a capsaicin molecularly imprinted polymer, which is a polymer prepared by the polymerization of capsaicin monomer as template molecules, functional monomer, cross-linking agent, azo initiator and porogen, and the polymer has high selectivity on the capsaicin monomer. The invention also discloses a preparation method for the capsaicin molecularly imprinted polymer, which includes the following steps: (1) the capsaicin monomer and the functional monomer are dissolved in the porogen, sufficiently mixed and then kept still, so that prepolymer is obtained; (2) the prepolymer is added with the cross-linking agent and the azo initiator, sufficiently mixed and then polymerized, so that bulk polymer is obtained; (3) the bulk polymer is ground into granulates, which are then eluted with methanol-acetic acid solution; and (4) the eluted polymer is washed with methanol to remove residual acetic acid until the eluent is neutral, and after drying, the capsaicin molecularly imprinted polymer is obtained. The capsaicin molecularly imprinted polymer has a specific adsorption effect on the capsaicin monomer.
